Does anyone know how much a full battery replacement for the Prius prime would cost ?

They cost between $2k and $4k, you can google them.

 

One dealer near me offers the five stack sub-assemblies for about $2,300 each; see my previous posting for the part numbers. There is a part number for the entire battery assembly, G9510-47180, but I’m not sure if you could actually buy one, since the sub-assemblies and other parts are sold separately. I’m also not sure why you’d want to, considering the difficulty and risk of handling and installing one as a unit.

 

Im getting $4-5k is more realistic since I dont think Toyota has favorable pricing when they source their batteries even though they buy a lot for all their hybrids. considering li-ion batteries are already at $100/kw for some companies, its possible that the traction battery itself will not cost more than $1000. Plus another $1000 for all the packaging and electronics. $2000 for the entirety of the traction battery is possible. But I dont think its possible with Toyota. Oh yea, then there's the installation labor.

 

toyota doesn't price batteries based on their cost, they price them at what the market will bear

 

That’s for all of the stack sub-assemblies. As shown in one of the illustrations for catalog Figure 82-01, Battery & Battery Cable, the battery assembly (G9510) also includes the battery computer assembly, wire harnesses, ducts, panels, labels, etc., which presumably could be re-used if the only problem is that the cells have worn out.

I’d suggest confirming the prices and availability with a dealer, of course, before relying on them; dealers’ web pages don’t necessarily reflect reality, especially for parts that the dealer may never have stocked or sold.

 

What risks are you referring to? Since the entire battery weighs something like 280 lbs, you don't think about doing it by hand, you need an engine hoist to install or remove it. Electrically, it's a non-issue because the first thing you do is pull the safety disconnect so the pack is basically dead.

I'd think it's safer to deal with an entire battery assembly with all the covers in place than try replacing one stack. Wouldn't a new stack cause balancing issues between new and old stacks?

 

I was thinking mostly of the risks of personal injury or damage to the car from misadventures while lifting and handling a relatively heavy object with close clearances, even when using a floor crane and the other material handling equipment shown in the Repair Manual (more info).

I haven’t done it either way, and to be sure, even just one sub-assembly is heavy enough to need careful lifting.

I wouldn’t expect a problem if all five were replaced simultaneously with new parts, but they can also be replaced individually. Either way, the Repair Manual says to run the “Battery Diagnosis” (forced discharging) and “Battery Status Info Update” utility functions (using a Toyota Techstream diagnostic system) whenever stack sub-assemblies are replaced.

 

It costs $0. There is a ten-year warranty on the hybrid-system traction battery.

 

How much is a PIP battery?

ive never seen a price for that either

 

Maybe $300~500 USD?

 

I have many answers to your question:

Your Prime battery is under warranty for 10 years, so until then the cost is zero.

Your Prime battery is not likely to fail for 15 years, so it is not likely to cost anything.

Retail price today is likely to change in 10 to 15 years so you will get an inflated price now compared to when you need it.

As a owner of a Gen 2 Prius, it's battery cost went down year by year. I cannot guaranty the Prime will do the same, but that is the way to bet.

But if you did something to your Prime that invalidates the warranty, I bet they are expensive now. So try to ignore your battery, tinkering is bad.

 

My understanding is that traction batteries don't just completely fail. A small number of the individual cells fail and there are companies that specialize in finding and replacing the failed cells and either sell you a rebuilt battery or repair yours. So while it might not make sense to replace the battery in a ten-year old Prime with an $11K new one, it would be reasonable to pay maybe 10% of that to refurbish it.

 

It’s fair to point this out, but keep in mind that the warranty for the HV battery also expires after 150,000 miles (or on older models, 100,000 miles), which could be reached much sooner. Has anyone compared the average annual mileage for Prius Prime cars with that of the U.S. passenger car fleet as a whole?

One edition of Toyota’s Flat Rate Manual allows 2.3 hours for removal and replacement of the hybrid vehicle supply battery assembly (operation number 890111, ZVW52 series).

See my previous posting for the price of its stack sub-assemblies.

 

OP - tell them:
$0 for up to 10 years and 150k miles.

After that its someone else's problem - I doubt we'd own it past then.

 

HI: My 2017 prime has 31K mile . Battery can only charge to 24 miles now, 3 years ago it was 36mi for few months. I noticed it has degrade from 30 to 24 mile since the pandemic in Feb2020 -only driven about 800 miles since then. Does that sound like a defect? thanks

 

I have two answers:
1) If the battery works at all, I bet Toyota rejects any claim,
2) When the car was new, it estimated some generic driver, but with time, it learns how YOU drive and makes better estimates. For some drivers, the range goes up, for some drivers the range goes down. It might be interesting to 'reset' the car. (It would be a pain to have to retrain all your preferred settings)

 

How many miles you get is totally meaningless. That's just a measure of how cold it is and how heavy your foot is. How many kWh the battery can hold is what matters. A couple weeks ago, I got only about 24 miles because the temperature was in the high 30s here. Yesterday I got almost 32 miles. It was the same route. The only difference was the temperature.

My 2017 is about to turn over 49k miles. I checked the day before yesterday after buying gas for the first time in 3,500 miles and it took a little over 6,100 Wh (6.1 kWh) to charge the battery from fully depleted. Here are my numbers since I started checking on it just over a year ago. They will vary due to variability of how far the car has dipped into the HV capacity. Note that yesterday was the highest I've ever recorded.

 

Jerry, are you using 120V or 240V charging? 120V charging takes a bit more from the wall than does 240V charging, mainly because you are operating the charger electronics and fans and such twice as long.
