Li-ion traction battery life?

As for the LiON batteries, there are several chemistries and some reports of formation of inert by-products. Just we're not seeing enough information to make any hard claims about the wear patterns.

Couple things. The Prius v in EU has Li batt - seems A-OK as far as I know. But I believe we have some recent posts, technical papers by Toyota, about their new "Gen2" Li batt...so there is no guarantee that PiP or v past experience is exact guide. Having said that the Li batts have been good and nobody is expecting a problem if anything better is expected here in USA we have positive feeling about Lithium batts. Maybe that's why Toyota gave USA the Li batts otherwise NiMH is the Gen4 norm.

 

i think pip just cracked the 100,000 mile mark. but keep in mind, there's a lot of pure ev vs mostly hybrid running on yours. i'll take a wager on long life as good or better than nimh. don't know which will fare better in the warmer climes though.

 

IIRC I read somewhere that Li-Ion loses up to 20% of its capacity over 5 years and this was a time related consequence rather than mileage. It put me right off keeping my Prius+

 

li-ion battery have same warranty as NiMH in 2016 Prius? I would guess yes.

 

correct.

 

My service writer has a 2006 and it is crashing at 185K. I told him it was time for a new Prius.

The 125K warranty is no accident. This stuff is well planned out.

I trade at 70-99K.

Forum is full hot at this time.

 

ive observed a very low ratio below 200K kms

it is better to change bfr if one can

Who knows, but I do hope it lasts a very long time

 

I usually trade up after 10-12 years, regardless of miles. The technology and safety features seem to change so fast.

So what did I do??? I bought a new Prius with NO Toyota Safety Sense stuff! Well, maybe next time around. (In the meantime, I actually have to be a non-distracted alert driver! )

 

Given the 10/yr150kmiles California warranty (in CT) on my new 2016 Prius 3, Toyota seems to have confidence that the LiOn battery will last longer than that.

There were early studies that determined that a 50% capacity reduction had almost no effect on MPG in a Prius.

Yes, Jeff, I'm sure it will last a long time. All the hybrid cars seem to be using L-ion now? And Tesla built that huge L-ion battery plant. (I don't understand why Toyota kept the older battery in the 2016 Two model.)

 

I would assume it was to Save money, Since the two is the base model.

I wonder if the 2017's will all be Li-Ion or if the two will remain in NIMH purgatory?

 

Not sure which is the best as the NIMH has had outstanding results compared to Honda batteries. But hope the lithium is better.

 

My suspicion - in Japan, a car over 5 yrs old is OLD. So, the relatively untried Li-ION batteries are fine there.

Most of the rest of the world is getting the tried and proven Ni-MH batteries. Maybe once (or if) Li-ION are proven over longer time-spans, then we'll see them in PRIUS.

Check out appliances with Li-ION - my Notebook computer at 3 yrs will hold ½ the charge of new, 2yr old CellPhone about the same, 3yr old GPS/SatNav battery lasts 10 seconds now. I hear Nissan LEAF batteries aren't lasting long times either. Plus they've been implicated in fires and explosions.

 

When the batteries do start to go they'll be easier to rebuild. The NiMH batteries depended on factory matched cells. This is why rebuilds typically fail. Li-ion uses cell level battery management system. Swapping out a bad module should be OK. The BMS should make everything play together.
