2017 - 2021 Prius Prime - 8.79kWh Battery Deep Dive

[@jessievaca]

Thank You for your informative videos! I have a 2017 Prius Prime Advance and recently noticed the battery is not charging as much as it did before. I used to charge and it would tell me I had 28 or 29 miles of EV driving range now it only goes from 22 to 24 miles of range. Not bad really but I really love this car and was wondering if anyone out there is doing upgrades of this battery to up the range past the original amount? If so please point me in the proper direction and if you know an estimate on how much it would cost!

[@gangpw924]

great video thank You, my 2018 Prime, 869 miles so far, halfway through my 1st tank , the daily EV commute experience is amazing

Thank you! About 150 lbs (68 kg)

[@jackonthefarm5540]

Wow. Just discovered your channel looks like all great content. I am a retired mechanical engineer that recently self educated to build an electric conversion car. As of this month I am able to drive my 1983 VW Rabbit convertible. I have 144 Li-Ion cells configured as 3P48S. Each cell is 72 Amp-hours. I have an Orion Battery Management system and 6.6 KW charger with CAN bus control. Interesting to see how Toyota does it. My battery weighs 575 pounds. (Had to buy custom made rear springs!)

Professor; After watching the complication and the time element, this is definitely depot repair work; No doubt the dealerships remove and replace the whole unit. I appreciate your detailed explanations and patience in producing this excellent video for those of us interested in the engineering of battery products.

[@WeberAuto]

Thank you. You are probably correct

[@jfbeam]

Yes, the dealers will remove and replace the entire unit. Unless it's damaged, there will be no power outside the casing. Once shipped back to a service center, they'll open it up and replace whatever needs to be repaired. (I was just looking to repurpose some, and toyota lists each subunit as an FRU.)

Hi there! You are really knowledgeable about all this stuff. Thank you for making such great videos. I have watched several of your videos recently regarding the batteries and working with them. I have a suggestion for you... At the beginning of each video, I think it would be a great idea to say "this is how to discharge these batteries"...and demonstrate it. I may have missed that. I think it'd be a good addition because many people without knowledge of the dangers could be helped in that way. Great stuff!!! Best wishes to you! Pat

[@ChargedUp]

Another great video - so max charging amperage would be 30A I'm assuming? What would be max charging wattage on the Prius Prime?

[@WeberAuto]

Thank you! No, I think the Prius prime max charging rate is 3.3kW, so at 240V the current will be 13.75A

[@IACaptainKen]

Thanks for the video John. I just traded my 2012 Prius 2 for a 2018 Prius Prime last April. Just drove from Ames, Iowa to Minneapolis and back this past weekend. Made the round trip of 490 miles on 9.26 gallons of gas. Did not recharge the battery in Minneapolis so only took advantage of the electric mode only on the way there.

[@russellennis7428]

1 generation Prius 46.7 going 60 to 70 it's amazing 177 thousand miles on car I am ready get prime when the price drops

[@stevebollinger3463]

The other two posters are right. Because all the cells are in series, the current is the same everywhere. So every cell, stack or the entire pack is rated at 25Ah. Think of it this way. Each of those stacks is 1.76kWh and the whole pack is 8.8kWh, right? So each stack has 1/5th the capacity in kWh of the entire pack. But each stack also has 1/5th the nominal voltage of the entire pack too. So to have 1/5th the kWh capacity as that of the pack each stack must have the same nominal Ah rating. The same is true of the individual cells too. Only if you have multiple cells in parallel like in the Chevy Bolt do you have varying Ah (or A) values within the pack.

[@WeberAuto]

That makes perfect sense, I had that wrong. Thank you!

[@mikel4879]

Steve B / Yes, you can have different amps ( current ) but the power remains the same ( parallel batteries = less voltage, more amps ; in series = more voltage, less amps ).

Hi Prof, what's your views on Tesla's batteries and their electric vehicles technology. Thanks

[@WeberAuto]

All Tesla models are high tech, but in my opinion, the model 3 is the most advanced inverter, motor, and battery technology available today. The inverter uses super efficient SiC IGBTs. This will allow much higher battery voltages than before. This will also mean greater range in the future.

[@laohantun7404]

Thanks Prof......bless your heart......things that I wanna see now able to see through your teaching.....

[@barryw9473]

Thanks! Did you verify cell manufacturer as Panasonic? What is composition of gas that could exit cells? Are the cells the VDA PHEV2 format? Are you sure lowest SoC is at 3.48 V? I would suspect much closer to 3.25 V? Can you explain why 3.48V? Thanks!

[@WeberAuto]

I did not verify that, but I did see a Toyota press release announcing the partnership with Panasonic showing a prismatic battery cell that looked just like this one. The Lowest SOC in the vehicle was 3.48V on a Toyota scan tool before the ICE started and began charging them. Thanks for watching

[@barryw9473]

@@WeberAuto thank you! It is a shame Toyota did not put 37 Ah or 50 Ah (already a few years old now) cells in this car. Instead it got 25 Ah cells that is tech from about 10 years ago.

[@Trades46]

Despite its small 8.8 kWh rating & less advanced design when compared to the Volt or Bolt, you have to be amazed how Toyota retains its conservative nature when it comes to battery thermal management in terms of cooling & heating to keep it at optimal temperatures. In that same respect, I almost want to shake my head at how cheap Nissan was that even the newer 2018+ Leaf 40 kWh does not even possess a fan to cool off its larger & more stressed battery pack. I just recently brought a Mitsubishi Outlander PHEV. The car is brilliant & I have been learning much through technical papers on forums. Are you interested in taking one apart and doing an analysis on that car anytime professor?

[@WeberAuto]

Thank you for your feedback. The Leaf is a huge disappointment. As for the Mitsubishi, I am interested, but it is unlikely I will ever have access to one. They are not a popular brand around here

[@MaxSachs]

Amazing detailed video and a real pleasure to watch thank you! Some years ago I had some 1st generation Sony Konion VCT1 cells for a high-powered ebike I made--196 cylindrical cells to be exact--and it had a nominal energy density of 19.1kg / kwh. 2007 - 2010 IIRC. I put it through hell and back and after about 400 cycles the custom pack finally dropped to about 90% of original capacity in roughly 2 years, still quite useful but voltage drop and range took a noticeable hit. If I had used actual spot welds and not solder iron and copper strapping it might have lasted longer :) This prius pack has nominal energy density calculated at 21.6 kg / kwh in prismatic form which is fairly impressive, yes it's years and years later but back then prismatic cells could barely scratch 25kg / kwh and you wouldn't dream of applying a warranty anywhere close to 8yrs 160000km. We only ever used prismatics for low power demand stationary banks because they sucked for anything else! Toyota and Ford have done something amazing here: high power density, high energy density AND long life! Could definitely see myself harvesting some of these cells for my son's e-ATV and not worrying about it.

Because all cells are wired in-series, *every* cell in the unit is rated at 25 Ah. Only if the stacks were in parallel, would you multiply Ah by stack count.

[@WeberAuto]

The Prius Prime battery (all 95 cells) is rated at 25Ah and it's voltage is 351.5V, its kWh rating is 25Ah x 351.5V = 8787.5 Wh or 8.7875 kWh.

These videos are great for the people who think EV and Hybrid batteries can't be repaired and must be junked and replaced. Failed modules and cells can be replaced by qualified techs or shops, I would expect businesses who specialize in battery repair to become common in the next 10 years. You wouldn't usually replace an engine for a burned valve or bad fuel injector but some people assume a battery is not repairable. More techs just need proper training on how to deal component repair in EV systems.

Hey John! Thanks for what you do. Do you know if the newer Prius uses the same cells? Have you dived into one?

[@JohnClulow]

I'd guess each heater section has a different wattage, accounting for the design differences, these wattages being chosen to obtain rough equivalence of heating rate with a given ambient. You allude to this. Regarding "safe" DC potentials, these are assuming some typical resistance for human skin, and this _can_ very substantially depending upon moisture and electrolyte levels. Regardless of regulations, always err on the side of caution since it only takes 100 mA across the heart to cause it to go into fibrillation. A cut in the skin can immediately drop resistance. A DC voltage under 50VDC could easily prove fatal if delivered below the skin and across the heart.

[@WeberAuto]

Good points, thanks for sharing

[@beforebefore]

In the heaters, they don't use Copper wire, but Nichrome wire. Copper has too low of resistance, Nichrome is high resistance and is used for heating elements of all kinds.

Love the videos.. glad to see you back doing your great explanations of these cars. Does anyone else get the feeling this battery pack was an afterthought.. it seems the pack is constructed of extruded aluminum, and does not really mold itself into the car well. The previous gen priuses had stamped steel battery containers that were molded shapes... This one seems very square and just bolted into the car. Maybe it was the best they could do with the existing vehicle..

[@WeberAuto]

Thank you, I had the same initial thoughts. The more rigid construction could be for crashworthiness. The previous generation Prius batteries were is the safest part of the vehicle (between the two rear wheels). This model extends the battery into a rear crumple zone.

[@imho7250]

WeberAuto, @10:26 you said the entire (1p95s) battery is 25ah. Then you said one stack (1p19s) is 5 ah. But as nice-Oscar mentioned, each cell is 25ah. Each cell would be 3.7v 25ah, each stack would be 70.3v 25ah, and the whole pack is 351.5v 25ah. I have know doubt this was just a brain fart that you didn’t catch during editing, because you know the only way a battery can flow 25 amps for an hour is if each parallel group (in this case, each cell since it’s 1p) can flow 25 amps for an hour. Thank you for all the hard work. This is hands down the most informative auto repair channel on KZbin.

[@Maltanx]

Thank you again for posting such detailed videos. After seeing all your battery disassemble videos, i have one question: why there is so much difference in energy density with the batteries? This battery is just 8kwh, and the battery of the chevrolet bolt is 60 kwh, however it seems that the size of the chevrolet battery is no more than three times the size of this battery. I noticed that the lower the capacity of the battery, the bigger it gets in proportion to the capacity. I thought that since the electronic takes about the same space in all the batteries, the smallest ones would need much more space in proportion, however the difference still seems too big to explain it this way.

[@WeberAuto]

The larger physical size of the battery cells, the higher it's capacity in Amp hours (Ah) will be. The more cells you wire in series with each other, the higher its voltage will become. The kWh rating is the product of both of those. For example, the Prius Prime battery is rated at 25Ah and it's voltage is 351.5V, so it's kWh rating is 25Ah x 351.5V = 8787.5 Wh or 8.7875 kWh. The Bolt EV battery is rated at 162.7Ah at 350.4V = 57,010 Wh or 57 kWh. I hope that helps.

[@WeberAuto]

Air cooling takes up more space on the Toyota battery verses the liquid cooling on the Bolt EV battery. The Bolt EV battery has very tight and compact electrical connections between battery modules verses the electrical harnesses that a Toyota is using. If you compare mass, the 25Ah Toyota battery modules at 186 lbs to the 161Ah Bolt EV battery modules at 800 lbs, the Bolt EV battery has much higher density.

[@ClockworksOfGL]

Nax FM - Liquid cooled batteries (like on the Bolt) can be tightly packed together, compared to the Prius’s air cooled pack. It’s also possible (and I’m merely speculating here) that Toyota made a trade off energy density - at the chemical level - for better stability at extreme temperatures. IIRC, using more manganese in the cells makes them more tolerant of abuse, at the expense of physical density. The Bolt, Volt, and Tesla cars’ liquid thermal management systems allow them to keep the cells in a tight temperature range.
