Wasn’t the same concern with the Toyota Prius when it was first released? Only for all the doubters to be proven wrong by the taxi drivers who kept beating Priuses for decades.
In any case battery failure seems rare but it still is catastrophic and nobody can afford replacement. Hence companies should just provide some sort of warranty / insurance product for the few unlucky folks. Seems like an ideal candidate.
- foreigner 3mo agoThey do.
- ZeroGravitas 3mo agoGenerally enforced by regulation, particularly tied to any government grant program to encourage EV adoption.
- Exoristos 3mo agoThose old taxi Priuses have had their batteries replaced.
- duskwuff 3mo agoThey were also using NiMH batteries - a completely different chemistry from modern lithium batteries.
- bfjvibybd6cuvu6 3mo agoLithium EV batteries are regularly serviced and repaired?
- Taniwha 3mo agoThe original Prius batteries can easily have individual cells replaced (mine is 20 years old, we've replaced 2 cells) - of course Toyota want to sell you an entire battery, the wrecker will sell you a whole bunch of spares (do this with care, an entire pack is hundreds of volts)
- dzhiurgis 3mo agoGenerally you can't replace cells unless you find perfect match - needs to be same resistance and capacity. Only on very large scale this is possible. That said on most EVs blown cells are very very very rare. Mostly it's balancing lead that looses contact.
- Taniwha 3mo agoThese are NiMH cells (7V) wired in series (not parallel so matching is less of an issue) - one bad cell and the series resistance of the whole string is shot
- dzhiurgis 3mo agokia ora. interesting to know. so they are pretty small packs and their design doesn't really apply to large packs.
- timbit42 3mo agoI replaced some of the NiMH cells in my Prius traction battery by buying some Prius traction battery cells on eBay for $20 each. Still working fine after 2 1/2 years and a lot cheaper than buying a refurbished traction battery for $3,000. My Prius is 2006 so any cells from the Gen II models (2004-2009) work fine.
