2017+ Prius Gen4 battery NiMH to Lithium swap - step by step

[@TheJahangirkhattak]

comparison between Range and power, before and after lithium batteries plz?

[@mitchellnissen6466]

Hi jack, If the higher trim comes with Lithium anyway, is the ecu/inverter capable of being altered so it treats these lithium cells as if they wer oem lithium cells? If the charging logic is set up for NiMh then there is a lack of optimisation that might lead to premature degradation of these cells, right? How possible is it to upgrade the charge/discharge logic to help ensure longevity of your batteries?

[@u3b93]

Well while Jack deserves a lot of credit for bringing this solution to the market, which consists of replacing the cell chemistry NiMH with LiFePo4 or Lithium Iron Phosphate, by a drop in replacement of two Toyota modules with one Nexcell module, he does not address the fact that the car has no notion of the new cell chemistry in the battery. NiMH with respect to Lithium Iron Phosphate chemistry have different charge and discharge profile in terms: -> Maximum peak charge and discharge currents as well as for how long -> Maximum sustainable charge and discharge currents without deteriorating the battery health/longevity The Toyota NiMH modules are 6S1P in configuration, since this drop in solution replaces two original modules with one Nexcell module which is 5S1P of LiFePo4 which kind of matches the voltage profile. Thus 12S1P NiMH cells are replaced by 5S1P LiFePo4. Chemistry |Min. Voltage |Nominal Voltage | Max. Voltage --------------------------------------------------------------------------------------------- NiMH 0.8 1.2 1.5 LiFePo4 2.5 3.2 3.65 In terms of modules the voltage are: Chemistry |Min. Voltage |Nominal Voltage | Max. Voltage --------------------------------------------------------------------------------------------- NiMH 9.6 14.4 18.0 LiFePo4 12.5 16.0 18.25 This is why I agree/rejoin your questions/comment.

great! do you notice any difference in performance and MPG increased?

[@sedatnet]

Corolla (E210) with p610 transaxle (same as Prius gen 4) is produced here in Turkey for European markets. I don't know if NiMH structures are also same (but probobly same) and you can sell this upgrade for Corolla users soon. I tried with OBDLink LX to measure the battery performance but it is not competible. Is Dr. Prius competible with Corolla(E210) Europe version?

[@hybridapp7158]

NiMH is the same for Gen4 including Corolla, OBDLink LX is a bit tricky, it doesn't really supports iOS and even with Android I found it harder to pair compare to other cheaper alternative.

[@tonyinfinity]

So thanks for wasting my time watching this. You should take this video down if "the project failed"?!

[@tonyarntz821]

Hi Jack, great job. When you put it to the test, could you drive it down a long falling grade and see if it will run in EV mode, because the NMH's definitely cause havoc as soon as they hit 42 C . hopefully there will fix the problem.

[@hybridapp7158]

Yes, I've driven the NiMH for weeks and notice that it gets hot quite easy and performance degrade big time at around 110F, I actually have to re-shoot the EV range video several times because the NiMH dropping voltage so quickly and throw me off the script, LOL

[@Edward3DFX]

Can you make a swap from base 2016 Prius - to 2021 Plug in - w - hi cap battery?????

[@hybridsolutiondiagnostics]

Wonderfull video brow... keep it up...

[@batuhanereselli7217]

Could ı learn about product code that you have used high voltage service safety switch?

[@mr.j8297]

Amazing job, big fan of Dr Prius app, it saved me thousands of dollars in hybrid battery

[@physicalivan]

great job. you forgot your high voltage gloves and wait 15 to 30 minutes after disconnecting battery pack.

[@Sunset4Semaphores]

Why would you want to do this? NiMH is perfectly fine.

[@yurisip3887]

How about BMS for Li-Ion?

[@edsonmartinspoli]

Does the prius gen 4th have NiMH or Lithium battery?

[@BookPaLuy]

you buy Lithium where?

[@eyvalababa1]

The car that comes with nimhd battery is designed to charge that kind of battery pack.charging of nimhd and liIon is completely different 😮don’t put your car in a risk of fire

[@MowgliLA]

Great video, i dont know wht i couldnt find this video in youtube searching alll the ways, and then typed in google and brought me in here. I guess youtube hates you for not monetizing video. Hats off my man

[@asa-vp8io]

what about BMS?

[@user-mr.donald]

Great job.

[@NikolaySemenkov]

at 8:40 looks danger when he touched battery with bare hands and belly as left and right side still may have each 100V DC even thought he took nuts out, but cooper plates still could conduct electricity. We want to watch more of your videos. Please use rubber gloves or just remove that orange bar first, before touching battery with both hands.

[@Martinko_Pcik]

Does this battery management system have low temperature charging protection to prevent it's destruction in Canada ?

[@hybridapp7158]

Already tested in sub-zero environment for years.

[@punker4Real]

@@hybridapp7158 Have they tested in Death Valley,ca I live in the desert it can get to 110-115F.. (SUV parked in the shade)

[@physicalivan]

4th gen already comes with lithium?

[@Sunset4Semaphores]

It is a mix. Some 4th gens still have NiMH, but most were sold with lithium Ion batteries.

[@netprep]

Do you have any bat upgrade options for Prius prime ?

[@FoteinaOphiuchus]

still waiting :D

[@kevinyork4757]

Ever see a lithium battery explode... YIKES.

[@michaelfleischer]

Superb video! I also love your touch of humor as in "use a persuasion bar", etc. Thank you for this very helpful video!

[@Belktronix]

I'm guessing this Li cell can be used on a Gen 2 pack? Just got the red triangle from it sitting at the dealers for 2 weeks, block #2 was a volt lower than the rest... getting a new cat installed since some idiot thought I didn't need it. thanks

[@rompetrenko5474]

Tell me, what kind of solution is used to fill the copper contacts?

[@jkv9461]

There's just not enough info on this. Im calling bs. I hope im wrong because i want to do this.

[@khmerlove1song]

Hi, I've been waiting for the gen 4 batteries to be back in stock. You know when the next shipment coming in. Thanks

[@hike2bhuman110]

Outstanding

[@edwinbab3205]

How check 2013 battery how muchbleftnof life

[@SLVRFOX88]

I have this battery for my gen 3 I thought I could transfer to gen 4

[@kevinyork4757]

What part of that battery accumulates dust from the fan?

[@samiam1372]

Thank you for making this video man!!

[@copiani1]

How about BMS for Li-Ion?

[@edwinbab3205]

What side is temp 3 mine it gets hot than rest

[@michaeltran9879]

Hi Jack , can we do in Toyota Prius2 2016 ? Where can order lithium battery?

[@hoseinkhan6102]

Jack.where.can.i.get.aquatoyota.hybrid.battery.2014,model

[@harrisharis4009]

Jack you are from Japan

[@JessePike5]

Why not 2016+?

[@quacktony]

Hm, I thought the 4rh gen already came with lithium.

[@hybridapp7158]

only higher trim comes with lithium

[@云龙王]

不错

[@farhanasadhamadfilms3924]

Nice job
