    *WATCH PART 2 AFTER!* It includes an efficiency discussion: th-cam.com/video/oJL9MasBFvM/w-d-xo.html
    *IMPORTANT NOTE:* Obviously, I should have discussed efficiency, as I have in almost every video where I discuss EVs. EVs are often 3-4x as energy efficient, meaning you need *less* energy total to move a certain distance (compared to the very best diesels, they're about 2x as efficient). That's why a "3 gallon" tank Tesla can drive 350 miles. Again, as mentioned in the video, the sweet spot right now is EV passenger cars. When you talk about towing, freight trucks, trains, planes, etc, the weight gain is not offset by the efficiency gain. Don't believe me? Here's the math: th-cam.com/video/S4W-P5aCWJs/w-d-xo.html
    *UPDATE TWO:* I hope no one interprets this video as electric cars aren't cleaner/more efficient/better for the environment. They most certainly are: th-cam.com/video/6RhtiPefVzM/w-d-xo.html. Also an important consideration if you're in the market for an EV is buying the range that you need. A smaller battery has a significantly lower impact than larger batteries, and will offset its carbon footprint much faster. Obviously, this will result in lower range (city commuting, multi-car family, etc).

      Engineering Explained Question about towing:
      Why an EV car is efficient in towing the first 2 tons (its own weight), but not efficient in towing the second 2 tons (the trailer). I’m sure I missed something, I just don’t know what.

      Hey Jason, any chance you can do a video on Mazda's recent claim with the MX30 that for total life cycle emissions they chose to go with a shorter range smaller battery pack? They also state that if they were to go with a larger battery pack their life cycle emissions would be greater then an equivalent diesel. I would like to see if you can back out the assumptions that they use.
      On another note, I do not believe current or gradual improvements of Lithium Ion batteries are going to be suited to constant high load applications when there is a weight restriction (i.e towing and vehicle weight class regulations or as you started to get into - aircraft). We have not been seeing the industry get the specific energy high enough, fast enough, to even come close to matching the performance of liquid fuel powered vehicles, even if they are less energy efficient.

    You missed a few points:
    1. Engine efficiency: The electric engine is much more efficient than the combustion engine, that means you need at least twice as much energy from the gasoline than from a battery.
    2. Charging time: Filling a tank with gasoline takes less than 5 minutes wherever you are. Charging the battery takes forever, no reason to stop smoking ;)
    3. Electricity Grid Capacity: Assume you try to replace 50% of the cars by EVs, the grid would break down long before reaching that.
    4. Emissions: Just because you do not see and do not smell the emissions of an EV doesn't mean they are not there. Producing and recycling EVs is much dirtier, and also the electricity needed has to be produced somewhere and causes pollution. Some calculations showed that you have to drive over 100'000km until the emissions are equal, and much more to be more clean.
    5. Safety: If a car with combustion engine is burning the fire is easy to put out. If a battery is burning it will burn for a long time no matter what you do. There are of course battery technologies that are more safe but also heavier.

    As an electrical engineer, I can assure you that as batteries become more compact, the increased energy per volume will simply make the battery that much more dangerous to breakdown, outgassing, and explosive decomposition.

    Another thing about the weight of gasoline and that of ion-lithium batteries: As you drive, gas leaves the car in the form of exhaust. Once you have used the energy in the gas, you aren't carrying the weight of it around. With the batteries, you still are transporting the entire weight of the expended energy source, progressively losing energy but not the load it moves. Probably not a big difference, but a difference never the less.

      And then there's mining costs, the cost to mine the materials for battery consumes a lot more energy and pollution than just burning gasoline or even better, LNG. Then there's no good way of recycling batteries, yet. And then there's battery degradation, there are many countries in Europe and Asia where people don't use cars all that often. They just use public transport, which is more time efficient because of just how dense those cities are. If all of them had electric cars, the batteries would just be sitting around for the most part doing nothing. So if you don't use the electric car as much, on balance, it is more polluting vehicle compared to a gasoline vehicle. Electric cars only realistically have savings in net pollution when they cross a high mileage compared to gasoline vehicle.

      This is a common misconception. People almost always charge at night. Utilities need a ton more power during the day - and have generation capacity to spare at night. Using EV's improves resource utilization of that capacity and utilities **LOVE** that. Evidence of this is that almost every electric company in the USA offers cheap rate nighttime electricity as a deal for higher rate daytime usage. They do this to try to spread the load of dishwashers, washer/driers, etc. They **LOVE** EV's.
      Also if Elon Musk waved a magic wand and turned every car and light truck in the USA into an electric vehicle overnight - the total US electricity consumption would increase by about 15% - well within even our daytime capacity limits. But also, the shipping and refining of oil into gasoline and diesel consumes a MOUNTAIN of electricity...which is saved when people switch to EV's.

      ​@@holdmybeer123 The raw materials production costs for an EV are less than for a gasoline vehicle. Remember - no engine, no radiator, no hoses, no transmission, no oil pump, no fuel tank, no fuel pump, no air filter, no water pump, no starter motor, no generator, no exhaust system, no catalytic converter...EV's are *very* simple machines.
      Also, there are VERY good ways to recycle batteries. Tesla have built a battery recycling plant right next to their battery production system so the materials from old batteries are recycled directly into new batteries...in the same building! Toyota have been efficiently recycling Prius batteries for about the last 15 years. This isn't rocket science.
      Reclaiming old batteries is easy (Tesla actually pays the scrapyards to remove them) - and recycled materials are cheaper than mining new materials - so it's a no-brainer.
      Battery degradation is a S-L-O-W process on a modern EV. A Tesla battery is currently lasts at least 600,000 miles - about three times the life of a gasoline car...and their next-gen battery will last a million miles. Degradation was a problem with the older EV's like the Nissan Leaf - which didn't have battery thermal management - but that lesson has been learned and battery degradation is not a problem anymore.
      You claim that under-used electric cars don't save on pollution isn't based on reality...I don't know where you get that from but it's definitely not true. With a gasoline car, there is a problem that if you don't use it enough, the gasoline will go bad and it'll be hard to start and have terrible MPG. This doesn't happen with an EV.

    For anyone wondering why fuel has so much more energy density than batteries: Fuel requires oxygen, which isnt stored in the car. By being able to take in oxygen along the way without storing it significantly reduces the mass that needs to be transported. In order to burn 1kg of octane it takes over 2kg of oxygen.
    While this doesnt account for everything, it makes it much trickier for any alternative energy storage technology to be taken seriously.

      One day the world will realize that petroleum is the second most abundant liquid on Earth after water, the greenest liquid on Earth after water, and it is Earth's synovial fluid, the lubricant for the massive tectonic plates. I wonder how long before the UN cabal convinces the world that diamonds come from petrified dinosaur kidneys? Petroleum is made with hydrogen and carbon with heat and pressure, then oozes at approximately 30k feet beneath Earth. Fossils CANNOT exist past 15k feet, but Rockefellers paid scientists convinced the Geneva Convention successfully on premature science. Then it is burned to harness its gorgeous energy to gas form where the upper atmospheres of the earth process the gasses for the earth's greens to consume. The carbon then settles from the roots of the trees down to create more black gold. Water cycle anyone? Same ****. Global warming and climate change is NOT caused by humans, but by the Sun's 300 year cycle, confirmed by NASA, and we're right now exiting solar cycle 24 to 25.

    Energy density is a valid point to be considered when comparing gas vs. lithium cells. However, gasoline engines have much lower efficiency ratings than electric motors. So the the gas may have more energy per liter, but only about 25-30% of that energy will be used to take you from point A to point B in the car. The rest of that energy is lost to heat and noise.

  • @nvirostk6354
    @nvirostk6354 2 ปีที่แล้ว +120

    Good video. Love the practical, common item examples. One point that should be made is the gasoline engines have around a maximum 33% efficiency converting the latent energy of gasoline into mechanical energy, while electric motor and their required variable frequency drive partners have efficiencies in the mid-90% range. ICE engine powertrains also have transmissions and axles/differentials that are mid-90% efficiency while the electric powertrain has a single speed gearbox/differential operating in the high-90% zone. Doing algebra with a lot of rounding, we end up with ICE powertrains at 30% and electric powertrains at 75%. This means you need to take more than half the LaCroix cans off the table because it is a 2.5:1 ratio for the energy that actually gets to the road.
    Now, that is only in the car. Electrical energy still has to be made and those processes are incredibly inefficient and usually polluting. Even the best solar panels are only 25-30% efficient when new and are made from “interesting”materials.
    I’m all for electric but it is certainly not an easy slam dunk. It is a difficult problem with 10 lbs to put in a 5 lb bag. All this to say, I agree the ICE is certainly not dead and should not be.

      If you redo the math considering parallel serial hybrids with engines with 40% efficiency (Toyotas that today cost as roughly much as regular cars) and the fact that on the other side of an EV usually sits a GE gas powered 60% efficient turbine (or worst, here in the US), you may conclude hybrids are better deal, at least for the next 20 years or so.

    • @davidwebb2318
      @davidwebb2318 2 ปีที่แล้ว +25

      Don't forget that your power station is only 50% efficient. The grid transmission loses 8-12% of the electricity and then EVs lose another 40% (they are 60% wall to wheel efficient).
      Modern petrol and diesel engines are 37%-43% efficient. Multiply out the EV numbers above and you will see that EVs are actually less efficient at converting fuel to motion than a petrol or diesel car.
      As 60% of electricity in the US comes from fossil fuels it would actually use less fuel resources if people bought new petrol or diesel cars instead of EVs.
      Most people have fallen for the idea that EVs are more fuel efficient but they haven't actually worked out the numbers. EVs are cheaper to run because there is less tax charged on electricity than gasoline. People therefore assume they must be more efficient but it isn't really true.

Though questioning people for purchasing phones, EV's or literally any other Lithium-Ion battery driven piece of technology is the wrong place to put your ire. The truth is that many of the industries behind the development of the electronics and convenient objects that we use in our daily lives have truly corrupt methods to cheaply mine, create and develop these objects. We definitely 100% need to stop taking cheap shortcuts, exploiting human rights and leveling everything that we can in nature to just consume. We also need to put focus into recycling the materials that can be used more than a single time or in some other product that is also useful.
      I am also quite aware of the fact that in 2016, the usage of Cobalt in Lithium-Ion batteries was ~20% globally in early EV batteries, telephone batteries and all other electronic devices using Lithium-Ion technology. In 2020 the use of Cobalt jumped to over 60% globally in no small part due to the increased demand for EV batteries. This will continue to increase as we demand more and more EV's, telephones and digital devices using Lithium-Ion battery technology.
      We need to ensure that the mining and production of these technologies follows proper industry standards and does not continue to exploit cheap labor forces forced into horrible working conditions. This is a problem that needs to be handled, but the our anger needs to be directed to our local government representatives.
      No, I did not buy my PHEV because I thought that it would be a cute idea and make me cooler or better than others around me in some way. I bought a PHEV to reduce my CO2 and Carbon Monoxide footprint when I drive in my city, which is always full of start and stop traffic. Because Carbon monoxide emissions, unburned hydrocarbon emissions, nitrogen oxide emissions and carcinogenic particles from I.C.E. vehicles kill a large amount of people in our cities each year and the air quality in our cities is important to me. I live in a large urban center, and while I drive in EV mode I am not creating any of these toxic emissions. I also live in a country which produces over 60% of its energy using clean energy options, so charging does begin to make sense. I also chose to buy a PHEV vehicle with one of the smallest Lithium-Ion battery units possible while still getting the range that I actually need. My battery is an 8.8 KWh battery and it allows me to drive without using any petrol in the city. Am I right to have made this choice? I cannot really say tbh, but I am trying to promote cleaner approaches and maybe to optimistically hope that the industries behind them will also be held to better standards as we move forward.

You can't just turn a boiler on or off on demand. It takes hours to bring one online, and it takes hours to safely bring them offline. So they're great for __stable__ baseline load needs, assuming you're otherwise in compliance with other environmental regulations.
      But reality is, that natural gas burns more cleanly than most forms of coal. Which makes environmental compliance costs for emission abatement lower, in addition to being much easier to transport as either a liquid or gas rather than in a solid such as is the case with Coal. This also isn't to mention the coal-ash problems, and a slew of other solid and liquid waste issues specific to coal. Meanwhile, the newest Natural Gas Power plants are turbine plants, not boilers, and they can be brought online quickly and easily when the green power sources aren't producing, and can be easily taken offline when the green power sources are producing. Something that cannot be done with a boiler.
      Nuclear Power is experiencing a comparable because it also operates as a boiler plant, they take hours to bring up to full power, and hours to bring offline. It doesn't lend itself well to the "spiky" power grid that large scale Wind and Solar operations often introduce into a power grid.

    Dear EE: just like there's TCO, there's also total environmental impact.
    I'd like to know how much environmental impact there is for gasoline, like drilling, refining, etc. vs lithium batteries mining rare earth metals, polluted water, etc. Then disposal of the used batteries. Not to mention, some (much?) of the electricity comes from fossil fuels anyway, so then it seems like electric cars are just an indirect way to use fuel.

Business "deductions" are better known as business expenses which in tax accounting is negative income. This means anything you buy for your business is essentially deleting money from your yearly/quarterly taxable business income meaning it is as if you never made that money in the first place and don't ever have to pay the ~10-25% income tax on that money.
      If your "business expenses" conveniently align with things you use in your personal life anyway, such as La Croix or your "home office" or your "business vehicle", then you get to buy these things for "your business" and potentially use them in your personal life. Since most business people don't have clear lines between their business and personal lives and their personal lives are usually dominated by their business there is a lot of potential overlap between them.

    3:00 Something he forget to mention is that IC engines have efficiency of 20%-25% while EVs have efficiency of 85%-95%. So, while you can still carry more energy per volume with gasoline, in the real-world value is closer to 4 times rather than 13.
    As for the batteries-only-for-personal-vehicles argument: the mining industry have been electrifying for decades and in EU BEV long haul trucks are on the rise. A BEV semi truck saves €50 000 - €70 000 a year in diesel costs alone (a back-on-the-napkin calculation). BEV trains are also in development in many places as replacement of diesel one on non-electrified tracks.
    While airplanes are indeed not suited for battery power, many if not all other type of transport can be electrified, making it cheaper to run in the process. While R&D in ICE shouldn't stop, it's really annoying to see the old car manufacturers making up excuses just because they already have the people and facilities in place of ICE

    There is some error in your energy density comparison representation - you show that a Tesla battery can only hold the energy equivalent of 3 gallons of gas. If your math & sources are correct (which I expect they are), there must be some additional variables (such as the energy that is wasted into heat, or how completely the fuel is burned) which are relevant to the discussion - how efficient the engine/motor can translate that energy into work matters. (Which is why a Tesla can travel more than ~90 miles even without regenerative braking despite only having ~3 gallons of gas worth in energy in the battery).

      Nobody talks about it because nobody cares. If the American consumer cared about such things we'd have the best public transportation in the world right now or we'd all be driving gas sippers. Green is not what's driving EV sales. EVs will crush gas cars just based on the metrics that do matter to consumers. Style, performance, economy, reliability and utility. EVs can hit all those marks in a single model. That's just today. Five years from now, gas cars will be on their heels.

      Hydrogen is a dead-end. Aside from Japan and a couple of cities in California - there are no filling stations...if there are no filling stations in some particular area, nobody can drive a hydrogen car - and if there are no hydrogen cars, nobody will build a filling station that nobody will ever use. This "chicken and egg" problem is fundamental. Also, hydrogen costs around four times as much per mile as gasoline and twelve times as much as electricity - so it's HIDEOUSLY more expensive. The cars also cost about twice what an electric car costs - and that's with Toyota selling them at a massive loss. Also, current hydrogen production uses fossil fuels and produces considerably more CO2 than a gasoline car. Japan has quite a few hydrogen cars - but it's a VERY tiny country (in terms of square miles) - so it's not hard to build enough filling stations. But Japan buys hydrogen from Australia - which makes it using the nastiest fossil fuel out there ("brown coal"). So (in effect) Japan causes a LOT of CO2 pollution - but can blame it on Australia. Hopefully, Australia will do something about that - and then Japanese hydrogen car owners are screwed.

    I don't remember him saying anything about the generating of the electricity. He sounds American. In the USA, 80% of electricity is generated from combustion of fossil fuels. It's even worse, because so much of the energy is lost in voltage conversion and long distance transmission. Then in the EV it is converted to chemical energy for storage. Then the chemical energy is converted to electrical energy to drive the motor. This doubles the amount of energy required at the generation stage, requiring far more fossil energy than a petrol car that converts that energy directly into shaft power. End result, EVs are likely to increase global warming more than combustion cars.

    when you said that a Tesla model 3 has the equivalent energy of 3 gallons of gas I realized that the comparison to making is nowhere near Fair. if a Tesla model 3 can go around 300 miles on a single charge, then realistically it's fair to compare it to around 13 gallons of gas. The reason for this is because electric cars are FAR more efficient at utilizing energy, plus electricity is far cheaper than Gas. As an example, depending on your state that 300 miles of range cost between $10 to $20 in a Tesla, while the average for a car is around $35 to $50, depending on the type of gas needed and the price in your area.

      solid state batteries will be the future but there still be an other obstacle in the way that need to be fixed.
      first they have to get out of early prototype as they are in now, second is 1000 miles range and 15min charge time will need extreme upgrades of the charging infrastructure, combined with very high voltages, ampere and exotic cooling. even today's fast charging cars need liquid cooling of the charger to not make em burst into flames now think 5 to 20 times that power.
      combine that with that some of the charging station companies take very high premium per kWh for the fast chargers up towards so high that it makes it cheaper to run gasoline even here in Norway where we pay around 2$ per liter of standard 95... (Tesla is going away from the "free" charging and disables it on second-hand cars)
      so if you have the time and can charge at home the slow way with an 10 or 16A line EV's are great.
      though while classic gasoline engine's got low efficiency but there is tech on the way and some "early versions" of it on the road already that makes the "just 20%" look silly.
      Mazda got the HCCI engines to work though with a little cheat in the form of the SPCCI, problem is that they don't like low or high rpm's when running in pure HCCI mode when they can reach as high as close to 70% efficiency atm....
      however atm there is no car yet that then utilise that in what would been the best form, a hybrid system ala Fisker Karma and Opel Ampera as a pure range-extender always running on the most optimal rpm.
      so ICE isn't dead yet, but soon it might be as the pure solution for movement.

    Great video but there is a significant flaw in one of your primary examples - energy density. The point you're making is entirely valid - and is in fact the key challenge BEVs face versus ICEs. But - numerically you've made an error that must be corrected. You state - correctly - that gasoline contains ~33 kWh of energy per gallon. However, this is thermal energy, not mechanical energy. We must use a device - in this case a gasoline IC engine - to convert that heat to mechanical energy. That is done with relatively low efficiency, limited by the laws of thermodynamics. As an example, in typical driving, it might be less than 1/3. (That means about 2/3 of that energy simply is released as heat.) We'll use 28% as a typical figure. As for the electric motor/inverter, it is going to convert the electrical energy in the battery to mechanical energy at something like 90% (and we must account for battery losses of perhaps 0.5%). For those getting giddy about this seemingly greater efficiency of the electric powertrain - remember that this low-efficiency conversion from thermal energy still must still happen in an electric power generation plant somewhere upstream that in most cases was necessary (and will remain necessary for decades) to bring charge to the vehicle's battery. But I digress. In the end, equating the useful mechanical power at the output of the e-motor and the IC engine - we get something like 1 gallon of gasoline as equivalent to about 11 kWh for a Li-ion pack. Diesel fuel has about 14% greater energy density (volumetrically) than gasoline, and Diesel ICE's are also more thermally efficient. Using 33% for a typical Diesel ICE efficiency, the numbers come to 1 gallon of Diesel fuel being about a 15 kWh Li-ion battery pack equivalent. These are still absolutely horrible numbers for the battery packs in comparison to most fuels, to be sure, but it's important to get this right. The chief advantage of the BEV (or a hybrid) is its ability to recover most of the energy otherwise lost to braking in the ICE vehicle, thus squeezing more range out of its small "fuel tank". But - where brakes are used little - such as in highway driving - this advantage disappears and the BEV has a real range problem. Battery weight (versus that of liquid fuel) is also a huge issue as you show, reducing vehicle payload. And that's not to mention all of the issues with high or low ambient temperatures and their effects on batteries..... There is a place for BEVs, surely. But they are no panacea and IC engined vehicles WILL be around for a long time.

    Very well said. The only thing I think you could have also mentioned is that there is a huge efficiency loss with the weight of the fuel source itself being less dense. Same problem rockets have. It takes for example 40% of the energy in the battery just to move the weight of the batteries themselves. Eventually the benefit of adding more batteries for more capacity exceeds the benefits due to their own weight!

      @Molt See if you can spot the oncoming disaster: It takes 84K gallons of fuel to produce EACH EV battery (21 billions gallons per year just to mine the heavy metals required for 250,000 batteries VS 19 billion gallons of fuel for the ENTIRE airline industry WORLDWIDE) - Per the US Dept of Transportation. PS - There is NO CURRENT ability to effectively recycle the used batteries…. The battery in an average Tesla is comprised of 25 pounds of lithium, 60 pounds of nickel, 44 pounds of manganese, 30 pounds of cobalt, 200 pounds of copper and 400 pounds of aluminum, steel and plastic… 1000+ pounds of minerals that had to be mined, transported and processed into a battery that stores electricity…. which was generated by oil, gas, coal or water…

But did you compensate for the fact that most of that gas is wasted though heat and power loss snd not used for propulsion?

    Love your show! I ran 170 ton Euclid, 120 ton Wabco and 170 ton Electrahaul, all were Electric Wheel Motor Haul trucks, in early-mid 80's. Top speed was set at 23 mph, empty they were extremely quick off the line, faster than ANY pick-up on the claim by far. They would hit top speed before pick-up could move 3 pick-up lengths. One more point of shortsightedness (if that's even a word) about environment is the fact that it takes about 500,000 lbs of ore (not including overburden) to produce the contents only of one lithium EV car battery. Nevermind the exponential rise in price and progressive scarcity of Cobalt, Silver, Lithium and others...Absolutely staggering.

      Look at the rare earth magnets in EV motors (like the T3 models): 1000-3000 kgs of radioactive slurry produced as a by-product of processing the Monazite ore get 1kg of neodymium. About 3kgs of neodymium are used per EV, meaning ONE EV is responsible for the production of up to 9 metric tons of radioactive waste. These slurries are usually dumped in open bogs where they dry out. The wind is then picking up the resulting dust containing uranium and thorium compounds and and is distributing them over millions of square miles - and in the lungs of people, significantly increasing the risk of lung cancer and leukemia.

    i agree with what you say but you made a "mistake" the energy density of a fuel should be multiplied by the efficiency of the engine(to see what the "usefull" energy density is), which is prety low for gasoline engines and really high for EV's (gasoline engines is about 20-35% while electric motors are closer to 85-90% so the comparison is off by a factor of 3)
