- เผยแพร่เมื่อ 27 พ.ค. 2024
- A Toyota Master Diagnostic Technician explains in simple terms how the high voltage battery works in Toyota Hybrids.
In this brand new series I will go over all components of the hybrid system explaining their basic function in a simple way that's easy to understand. The theme of this series is simple but complicated.
The hybrid system in Toyota cars is super complicated and a marvel of engineering. In this series I try to keep things simple and light so Toyota Hybrid owners can see how their cars work.
I believe if you know how your car works you'll be able to utilize all it's features better and better understand your hybrid Toyota.

As a college instructor for 20 years, I know that some people can be a master of subject matter but can't teach it to others. Helping someone else understand complex issues and making it easy to understand is a skill. It comes natural to a few and others never get it as hard as they try. AMD is a natural - I enjoy listening and learning from him. Don't change the recipe.
Thank you!

@@TheCarCareNut I am on the waiting list for a hybrid max grand highlander. The power plant of the new sequoia has been reviewed in full. I’d like to see a hybrid max review. Specifically does the hybrid max eliminate the alternator and starter motor with the parallel motor/ generator? This a great review of the hybrid at the date reviewed.
@@monacoprince398 I wonder why
@@TheCarCareNut G'day
Improper start up times before using a motor...
I've always been mindful of cold starts with cars
Getting them working before they've warmed up is harsh on components
I understand that most engine wear actually happens in the first few minutes
Have you noticed that hybrid motors fail before their dedicated gasoline do, because by design they aren't actually warm before working?
Or have I missed something?
Thank you for your time
He is risen!
This guy is good, clear, honest, knowledgeable and involving! Thank you for passing the knowledge on 👍🏻
He talks way too much. He needs to script his sht because its terrible
And so pleasant to listen to
@@JD-ml7cg I play all this videos at 1.5x speed.
@@JD-ml7cg man get off your high horse. Those of us who want to learn find all his explanation TOP NOTCH! Go troll somewhere else because he is utterly FANTASTIC!!
Just got a 2021 Prime for the same price I paid 20 years ago for a base model BMW 323i. The tech you get for your money is amazing. The latest prime is luxurious and drives very well. You don't feel like you're in an econobox.
I’ve owned a 2010 Prius for about three years. I had to replace the hybrid battery last year. But, it wasn’t the $6000.00 you hear people scream about. It cost me less than $2500;for a brand new Toyota one, installed. It’s not a luxury car, but it’s fun to get 49 mpg. It burns no oil.
I hope to enjoy it for a long time. I hope you do too!
@@MsNickie1001 how many miles did you get out of them?
@@Faisal-sf1gh the hybrid battery died after 115,000 miles. It was about 9 years old.
I am an engineer but you're video series is perfect for an overview introduction to the system. All that electrickery simply explained! Thanks for doing this. We are considering a Toyota Hybrid as our next vehicle.
Anyone that can make the complex simple is one that really understands what they are talking about.
AMD has the knowledge and is very pedagogical whenever he talks about anything related to the maintenance of Toyota vehicles. I think AMD is what TH-cam was missing regarding the maintenance of Toyota vehicles before he started this channel. 😊
Thank you Jonas and Spencer! It’s my pleasure to share everything that I have learned to help people.
Here here! I could not have said it any better.period...
I have owned a 9 Camry Hybrid 2014 and a half Camry Hybrid and a 13 Toyota Avalon hybrid... Needless to say I'm into hybrids...
A slice of history regarding the 55 Chevy. After you installed a "Bermuda Bell" then it became absolutely magnificent. Now back to the very good Hybrid tutorials.
Don't forget the glass pack mufflers.
We just bought a 2022 Highlander hybrid. We were clueless other than what the salesman told us. You are educating me on so many things concerning hybrids. Thank you so much for these videos!
I'm really looking forwards to watching your entire how hybrids work series. I've had 3 Priuses, and now have a 2020 Corolla 1.8 hybrid, and (apart from one blown bulb), never had a single problem with any of them. Amazing reliability for such a complex piece of electro-mechanical machinery.
My wife and I have had a lot of cars over the last 47 years, but for the last 16 years we have owned nothing but Prius. She got one new in 2002, and the reliability was so good we were astounded. I traded in a Nissan 300ZX for a used 2002 Prius in 2002, and we have had only one problem beyond dead 12V batteries in all these years: my 2002 had a bad inverter coolant pump at 196K miles. By far the most reliable cars we have ever had. I have no idea which would come in second place.
@@flagmichael Lexus
@@flagmichael I have 2013 Toyota Prius V and have put 184,000 so far. I had to replace thermostat at 183,000 and break pads. No problems other than that. On top of that I get 50 miles per gallon, saving so much on gas. It's like getting a rebate of $200 to $300 from gas ,for every 5000 miles of oil change .It's like saving $4000 to $5000 on gas for every 100,000 miles. Amazing.
I bought new 2019 rav4 xse Toyota hybrid.. with weather package, moon roof. Magnetic Grey with black trim. I love my car, get over 40 mpg.
AMD is smart and knows his stuff. His Credits are huge. Always good advice
Thanks for making it easier to understand hybrids cars , and how things are better or worse , and how reliable they are
I’ve just started to watch this series. I love how you’ve compartmentalized the video for different topics. Thanks.
From the depth of my heart - thank you for the huge work you made here. And for you sharing the experience with the audience.
Just found your videos while surfing on-line for replacing the 12V battery on my Prius. I am looking forward to the rest of the series - this is great! Thank you for these videos.
I am so glad I found your channel. You are seriously the best teacher about cars and taking care of them. I am considering buying a hybrid and I had no idea how they work or how to take care of them. They just appealed to me because of the mpg for around town driving. Thanks for sharing your knowledge.
Hi, thanks for the comprehensive explanation of the hybrid system my cars use. Coincidentally I replaced the battery filter in my Auris last week.
I'm interested to see your other video's. A lot of people have no clue how a hybrid Toyota/Lexus works. Now I've got something to say about it thanks to you.
I have a 2016 Prius, bought new in February 2017 (I got a great deal!). You mentioned around the 13-minute mark that you don't recommend storing the cars as it might affect battery life. Well, since I live in Nova Scotia (rust capital of the world), I have put my Prius in storage from mid-October to mid-April for the last five years (unheated barn). So far, no problems, so I am hoping my luck will hold! By the way, I now have over 100,000 km on it and my overall fuel economy for that entire time is 3.9 litres/100km--which translates to about 60 miles per U.S. gallon. I love this car! Thanks for having these great videos to help understand such a complex machine!
Dan I'm sure it will be fine, I have an 2008 and it was excellent for work, min. problems.
New subscriber and your new student here. I'm 65 y/o an old school mechanic studied and learned from days of distributors and carburetors. Now, I am learning again to connect my knowledge to the new car technology of Hybrid. Thank you !
I am a fire fighter. Knowing that there is a disconnect switch from the battery to the vehicles systems is VERY important for me to know. Our challenge is that if the battery cell is damaged in an accident how can we perform an extrication without getting shocked, or worse? Obviously we need to remove a viable patient from a vehicle as quickly as possible, but if the vehicle is charged, we are presented with greater danger for emergency crews. Any information in this regard, addressed to emergency response, would be much appreciated by many.
Toyota says any accident that triggers thr airbags also trigers the relays to disconnect the battery.
I think it would be a good idea to have a mechanism to flood the battery with nitrogen or sand, the problem with the battery is two fold, one the energy stored in the battery. Two the the energy of the battery burning
This is good information, but, as some may know, an accident is unpredictabble. Any damage to the battery could result in charging the entire vehicle, making extrication difficult or impossible. I now own a 2024 Sienna and appreciate how good Hybrids are, but many of you can understand the dangers that emergency workers face. Please keep this kind of information coming. A further challenge for us is that every manufacturer builds electric and hybrid vehicles differently.
Unless it's a plug-in hybrids the battery is pretty small and it's under the rear seat.
Thank you for explaining how the Toyota hybrid system works in plain and simple terms. This is a wonderful series showing how the various components work together to form the system. As always, the videos you post are very much appreciated. And you explained some of the strange noises that my Prius Prime makes . . . I'm going to listen for the four clicks from the traction battery relays the next time I press the Start button.
Thank you for the video. Very explicit.Good job. Keep doing this. My 2020 hybrid Corolla has Nickel metal battery.
Just bought a 2021 Corolla Hybrid. I am learning so much by watching your videos. You make learning fun!
Thankyou for doing this. You make it so anyone can understand the components and what they do. My hybrid experience was with the first and second gen Prius. We had an instructor that had us remove the battery packs and inverter/converters from two working Priuses with no problems. We took the covers off the battery packs he explained how to test the individual batteries and how each individual "cell" was 7.2 Volts "at that time." We learned how to clean the corrosion from the straps that connected the cells, what to torque them to after reinstalling them, how the small bolts were special that held the straps to the battery how each cell could be recharged, and even how a little problem came along after a while that caused a fuel mileage problem. Well, cleaning the straps, checking and replacing a bad cell (back then) followed by recharging brought the fuel mileage back to where it was supposed to be. Then the other group with the removed inverter/converter went over that with the instructor and both groups on that Prius reinstalled the inverter/converter, the battery pack and the safety plug. Once that was done, the vehicle had to start and not have any codes! Then we went to lunch. After lunch, we reversed positions and my group got to remove and learn about the inverter/converter by taking it apart, putting it back together and adding the coolant back into the reservoir for that part of the system. The vehicle had to start, not have codes, and we were done for that day. I THOROUGHLY ENJOYED THAT DAY IN THE SHOP WITH THOSE TWO PRIUSES! Several years later, one of our Prius's was in a wreck, I got to change engine coolant hoses, the radiator and other parts. Yes, I removed the inverter/converter, replaced several small coolant hoses under that unit, put it back together and since the Body shop had done their work, I finished the car, got it going and no codes.
I learned two things about that car. How to keep the transmission from going into park so the vehicle could be moved around with the engine off and keyfob removed, by removing a relay in the underhood fuse/relay box thanks to Carolyn who worked on Priuses in a different part of California and was a member of iATN like me. The second item was the early hybrids did not like to sit long especially in the Body Shop and sometimes would not start even with a full tank of gas. Seems the float in the tank would sink. A quick tip was to shake the back of the car from side to side and the float would regain its "floatability!" Then it started! Other than a couple small battery changes, I didn't do much maintenance to the other Priuses that were in our City fleet.
@carcarenut Thank you for all the hard work you put into your videos. I am an owner of a Highlander Hybrid and found your videos when I was trying to learn more about my car. Your videos are a Toyota owner’s dream! Thanks again.
I absolutely love and appreciate the content of your videos ! thank you so much for making them ! you should have like at least 1 million subscribers !
This is the exact corolla hybrid I drive, down to the cooler and all. I've known that the battery is under the seat, but had not had a chance to see what it actually looks like without the seat. I love this video, it was full of information but easy to follow, I really like learning about this system. It truly is quite simple once you lose the fear of the unknown. I also love that you explained the clicks those relays make, I always hear them clicking in and tried to imagine what was going on there, I just thought of it as electricity flowing. I've had the car for about 18 months now, I ordered all 3 filters, ac, intake, and hybrid battery, I figure it's a good time to do them all, I wonder what the hybrid one looks like. I had intended to change the ac filter but had some trouble finding it some months ago.
Thank you for watching! Here’s a video that shows you how to replace the filter and shows you how it looks like. th-cam.com/video/U7mjpvRihVU/w-d-xo.html
Great video, we are getting a new vehicle in a few months and this is the vehicle that I am leaning towards. this is the first video i have found that really showed me just how the car operates. thanks.
Thank you so much for all the work you put into these videos. I just purchased a 2023 Highlander Hybrid bronze edition today. Looking forward to studying more of your videos, including finding out where they're hiding that 12 volt battery in the rear of the vehicle. I need to hook up a 12 volt power supply to handle my amateur radio and I always go straight to the battery for that.
Please tell us how you ended up hooking up for the ham radio
I’m taking delivery of a 2022 Camry Hybrid at the end of this month. This video is a big help in understanding this system. Thank you.
Im looking at an 08 prius with 160k miles as my first car right now for 4500. This video has given me a lot of clarity to how exactly the hybrid system works.
Also loved it what you said about the hybrid computer talking to the battery computer.
"HEY!! LOSENUT BEHIND THE WHEEL WANTS TO GO"
Love this guy. So knowledgeable. Thank you.
Thanks for putting into layman's terms.. U are very interesting & a great instructor!
This is very important knowledge for the owner of hybrid Toyota’s thank you!!!
Thanks for excellent detail explanation of Toyota Prius Hybrid system, waiting for second part soon. Take Care from Toronto Canada
Thanks CCNut! I find your videos not just informative and clearly explained but relaxing.
Thank you very much for sharing your knowledge of hybrid cars.
This guy is honest and straight forward. I like him. None of this youtube smoke screen and mirror. Real content. Love it.
Good site,keeping it simple,just what's needed.
AMD you have evolved yourself over the last few years. I watched the reveal of the new studios/shop and saying goodbye to the old house. Wish i had a Toyota again and lived closer, TCCN would def be my mechanic
Awesome explanation. Very patient and informative. Thank you!
Good simpler version of Prof. Kelly explanations. Thanks AMD.
Very interesting and relevant, thank you. I'm not sure why it took so long for Toyota hybrid (or any hybrid) to take off, in terms of mainstream market demand. The fact that hybrid wasn't available on more of their models is a factor and they have continued to prove and refine their original design. Everything I've seen seems to suggest the battery lasts a long time, unless neglected or abused. The cost to reco or replace battery in 10 to 15 years is not bad, compared to other fairly common failures on other vehicles, considering the fuel and brake savings, etc.
I have a theory.
They should have used a stronger name than Prius.
So much enjoyment. I learned a lot! Thanks for another great video! 👍
Greetings from Australia! Great series on Toyota HSD, had my first hybrid car, 2020 Camry, since April 2020, best car I have ever owned! Would love to see you do some videos on using Hybrid Assistant app and OBDlink.
I havent bought a hybrid yet but i find this subject interesting and certainly convinced me. Thanks for the info
New subscriber here! I was thinking about buying a Toyota RAV4, but after watching him, I'm convinced it is the best decision it absolutely buy one!! Very informative and helpful!
Great video:) looking forward for next one.
After watching him in a number of videos, I am so happy I got the Toyota hybrid.
Excellent video. I have Prius V 2013 with 184,000 miles , no issues just thermostat went bad recently.
Man your insights are the best. Thank you for your contribution
Yes I agree on the Toyota hybrid system is one of the best... I am not a saved planet tree-hugging type of guy but Us hybrid Geeks need to stick together! 😆🤔
Good info and easy to understand. Thanks for sharing.
Thanks for sharing useful info.
Thank you for you contribution and caring contribution for educating us. I really enjoyed my two Prius vehicles, a 2003 which I had a trouble-free 150,000 miles with no hybrid issues even commuting off and on for 15 years over the Rocky Mountains; and a 2009 that went over 120,000 miles with no problems with the battery. Sadly, I had to buy a Subaru Forester in 2017 because at that time Toyota did not have a SUV that had as good highway mileage and a full-blown AWD system for a snowy commute.
I love this guy, I learn a lot with him, God bless you.
I have just bought a RAV4 2021 Hybrid. Man I love your channel, I’m a new subscriber too :)
This man can teach. I love his videos.
Brilliant - first time I'd actually seen these hybrid batteries -- good advice too.
Love the video. So easy to listen too. You sound like Adam Sandler!!!!
Those dislikes are from GM staffs 😝😝
Amazing! Not sure why it has thumbs down. Thank you for all your hard work god bless 🙏🏼
Thank you!
My hybrid battery still running strong at 170k miles original owner my dc inverter went bad at 120,000. Good thing it still had warranty 10 years or 150,000 miles i dont have any warranty no more lol. I replaced my water pump and egr valve good thing for youtube save lots of money.
Well done sir. Thank you very much
Thank you. I'm starting my DIY me mechanic adventure with my 2010 Prius.
Awesome! I’m trying to put more information on 3rd gen prius models. Do your research on each job you tackle and ask any questions you have!
@@TheCarCareNut Can you talk a bit about tools you're using or what's needed for DIY Prius owner? Big thanks from Ireland.
I’ll add this video idea to the list! In the meantime email with any questions specific to jobs you’re tackling and I can help with tools needed
@@TheCarCareNut I have heard a lot about oil consumption in the Gen 3, with lots of fingers pointing to the small drain holes in the oil control ring seats and subsequent coking of the holes and rings. However, coking makes me think the owners are using conventional oil (which can't be 0W-20) and/or neglecting change intervals. Any light you can shed on that in a gen 3 video would be great!
Gen 3 common problems videos coming soon. The oil consumption is a problem with these. There’s a TSB with updated pistons and rings but the issues goes to the 10k oil change.
Thank you for your knowledge!
Thank you for making this video it’s helpful to know how stuff works.
Very nice and informative presentation.
Wow, excellent, I love the way you explained about battery 🔋 pack. Thank you Sir.
Planning on buying a new rav 4 hybrid. Hope you make videos on the new ones XD. Great content
Thanks for sharing all this info. Vey useful
Thank you for helping me understand my car. You are my go to guy when it comes to my Prius😉
Thank you, brother. And may the Lord bless you and keep you and shine the light of His continance upon you and your videos!
Thank you so much for such a well explained video ! It wast most interesting and useful.
Great video, thank you
Just bought one...glad I did👍
Brilliant thanks great video
Very good explanation!
Great video and very informative.
Thank you for your awesome insight and video!
Awesome stuff! I absolutely love this guy and really wish he was my mechanic!
Wish we have this guy here in the Philippines. I learn a lot from you
Great video as usual
Thank you
Great job. Thanks
Very interesting!
Excellent presentation. Thank you. I am a Toyota lover. My 3rd RAV4 is a 2018 Hybrid. I love it. Really cool channel.
Thanks
Fantastic video. Thank you 👍.
I love your videos thank you so much for them and Lord bless you and your family too
very educative. thank you regards,
Thank you my friend !
Interesting video. 👍 There are six 1.2 Volt cells combined in a block = 7.2 Volt. Two of these blocks are connected into one module = 14.4 Volt. Inside the battery are 14 of these modules = 14*14.4 =201.6 Volt. Not something to mess around with. Special attention for firefighters that try to cut the car open in case of a crash! ⚡⚡⚡⚡⚡⚡
Thank you! It’s a very cool setup. Simple when you look at the simple math and electrical theory but complicated of how it’s actually constructed
Great video AMD thanks !
well explained for the average man to understand!
Nicely done. Thank you.
Well explained, thanks You , and sharing your knowledges 👍.
thank you for all the information....
Thank you!
Nice overview
Hi, great video. Do you know what the vents are for on the other side near the floor from the cooling fan intake? I have one of these cars and this is identical to mine inside, I'm very interested in how it works! I enjoy watching your videos. Thanks.
amazing stuff in youtube. thanks friend
as usual i turn to this man for knowledge
When I was 14 years old I helped a friend repair a tube-type console radio. When I got there he had the chassis and the speaker on the counter. It was a field coil speaker (in those days permanent magnets were not good enough to use for speakers so they used electromagnets) and I knew the coil was used as a filter in the high voltage. What I didn't know was that for reasons unknown to Man one side of the coil was fastened to the speaker frame! The next mystery is why I had one hand resting on the grounded chassis and I slapped my hand down on the magnetic structure, making excellent contact with 300 volts DC. I felt like I had been hit in the back of the head with a 2X4, and everything got pretty dim for a few seconds, but I did not fall down. If it had been AC I would not be here to tell you about it; DC is not as lethal, volt for volt, as AC. Later, when I worked as an avionics tech in general aviation - small planes - I got 275 VDC between my fingers at least a dozen times... a quick yelp and a couple seconds of muttering curses. My brother and I also managed (long technical story) to get our bodies in series with each other across the 800 VDC plate supply in an amateur radio transmitter. Quite a jolt, and we were left with sterile pits in our fingers. That said, it is still hazardous. Will contact with battery voltage in one of these hybrid systems kill you? Think of it as being like falling off a roof. The odds are probably in your favor, but you _really_ don't want to find out.
Very well said.
Very nice video 👏👏👏
