4.5 miles per kilowatt hour times 33.33333 kwh ( the hydrogen/energy in 1 kg of hydrogen ) equals 150 miles per kilogram of hydrogen, or 6.6 grams of hydrogen per mile. 5.7 miles per kwh would be 190 miles per kilogram of hydrogen or 5.26 grams of hydrogen per mile and 6.7 miles per kwh would be 223.33 miles per kilogram of hydrogen or 4.48 grams of hydrogen per mile. Dude, that machine is awesome.
I am not too familiar with hydrogen but understand 60 miles per kg is typical. So yeah this car is awesome. Also if you count the energy needed go get to that 1kg of hydrogen (I read 40 to 70kWh?), it would be very hard for a hydrogen car of any sorts to compete in terms of best use of raw energy.
Dude, it's not a comparison it's a conversion ( 4.5 miles per kwh x 33.333 kwh equals 150 miles per kg of hydrogen ). In other words if you put a hydrogen fuel cell in your car 1 kilogram of hydrogen will take you 150 miles ( about the same distance as a 400 pound battery ). Also, why do you care about the production energy for hydrogen, NOBODY cares how much energy is used to produce a gallon of gasoline and 1 kilogram of hydrogen has 7.69 times more energy than 1 kilogram of gasoline.
As usual, very good job. I have the same result on my Ioniq despite its 220000 km. I agree with the fact that 120 km/h it's the best speed on Highway and it's more true today because you can find easily somewhere to charge without plan route that much (in France, I don't know if it's the same in the UK).
Another brilliant video. I can confirm your global efficiency average with my Hyundai Ioniq28, driven for ~4000 miles this year: 4.48 miles/kWh. It’s ridiculous how reproducible the driving data are with this car! 🤩
We re lucky that the ioniq data seems trustworthy and there is a matching app/obd output that allows to get it simply. Sadly dont think that combo exists for many cars.
Great data, thanks. Is is possible to use it to do a comparison with the different consumption scenarios provided on EV database (ie city summer / highway winter etc), rather than the overall figure? I've never been sure how realistic the EVDB consumption figures are, or indeed how they are derived, and this could make an interesting test case.
Regarding the Ioniq28 or Ioniq38, EVdatabase (or even Hyundai themselves) is a bit pessimistic. Probably a good thing to counterbalance some of the unrealistic WLTP figures provided by some manufacturers but also so that people feel pleasantly surprised when they beat the known efficiency 😂.
Valuable information - thanks for sharing. It's good to see where the best efficiency is (around 70 km/h) for cases of emergency/turtle mode.... Your consumption data includes charging losses ? Otherwise 17 kWh/100km with 120 km/h seems a little bit high.
I expected an EV to have low consumption at low speed and higher consumption at higher speed. Now, your curve showed an optimal speed around 70 km/h. Still I notice a nice spread around curve it did show a higher consumption when driving at low speed. Why do you think it so? Because of heating up the cabin om short tips or what might it be?
Yes the ratio energy for heating (which is kind of constant as a function of time say 0.5 to 2kWh per hour) vs driving (which is expressed as a function of distance) means Wh per km have a larger component from heating if the car moves very little@@JorgeniLund
3:16 actually, when you go up, you are accumulating potential energy, which is then used and converted by the regenerative braking of the car into electricity to fill up the battery ☺️ But question: how did you adjust for altitude?
You're right. Bad use of terminology from my part re up vs down. And applying 463Wh/100meters which is taken from the Ep = m*g*h formula and I have measured from my mountain trips that there is very little further adjustment to make for losses on that.
@@evdabblerexcellent, I’ll take that into account for electricity/battery consumption when planning for a potential mountain trip. 👌🏻 unless you think that ABRP does take this into account, i.e calculates it from each EV’s specs?
Bonsoir! thanks for this video :) this next wednesday, I will be in Rouen to pick up my Kona 39kWh and drive it to Portugal. I plan to spend a night in Irun so I need to drive from Paris to there (750km) in one day. What do you recommend? do I drive on the route nationel (mostly the N10 until Bordeaux i think) or should I go highway? since this car charges slow, I think i should go slower speeds... sorry if this sounds dumb but it's my first time with an electric car :)) merci!
Good question. On a kona 64 I'd go highway without running the numbers, it's safer and easier, and if you want to minimise charging you can drive at 110km/h. On the 39 it's more balanced. The choice is between road at say 130Wh/km (check out EVDB), and motorway at c190Wh/km. If you charge at 37kW, you end up saving 2.5h of drive on the highway and losing an extra 1.5h of charging. Timewise highway wins. 1h better. Watch out as I'll post a short on this.
@@evdabbler thank you so much for your quick reply :)) so basically, in this 750km drive, if the national road route would only be an extra of 1h driving, it would be a better option since I'd save tolls, less charging stints and better prices (I'm looking at charging at lidl stations). did you take into account the highway driving at 110km/h? since it wont be as quick on the highway route as it shows in google maps, for example... edit: yes, you did! now i'm trying to figure out what i should do but it's great to know that on a drive of this distance, i can save 1hr even at lower highway speeds than usual. thank you so much, you're a legend :)
Thank you for taking the time to record and compile all this data 👍
Thank you
Someone who can put together a proper graph, love it!
Thank you so much!
That very useful to know and thank you for taking the time getting the data.
Thank you!

Wow, so much data 🤩 :-). Very interesting to see. Now I would need all that for all cars out there... That would be something!

Here you go. here is the answer on video. thank you for asking. th-cam.com/video/6krp6tiHZrM/w-d-xo.html

This is pre losses but on GPS speed. Let's not forget this is also a mix of outside temperatures (say 5C to 30C).
I expected an EV to have low consumption at low speed and higher consumption at higher speed. Now, your curve showed an optimal speed around 70 km/h.

Thanks for the video! Are the speeds in the graph GPS speeds or the speeds reported by the car?
I should have mentioned. GPS speeds. thanks!
Can’t wait to see similar analyses with the Renault Scenic 😉
We'll see ;-)

Thanks! Tools are Python/plotly

such a scatter plot, i wouldnt even use a trendline
Ignore the label, for all practical purposes it's the average of all consumptions for every km recorded in this speed segment.
Nice video, but wish you had also put on miles per kw.
