[quote=CDMA ENG][quote=patb][quote=joec]What about the concern that replacing all these batteries for ALL these cars would be expensive and a total pain after 5 years?
Like how your cell phone or wireless headphones or pretty much anything won’t keep a charge anymore after a certain amount of time. It could cost 10k to replace the batteries on the Tesla.
That’s one of my biggest concerns with owning one of these EV vehicles, even the cheaper ones.
Even with costs coming down, it’s still so much more than the $50-$100 standard car bat.[/quote]
people said that about Hybrid cars too. It didn’t happen.[/quote]
It will…
Battery technologies have made huge leaps in the last 15 years but one thing still remains…
They eventually fail.
Sometimes spectacuarly…

I have a lot of hope for LifePo4 batteries instead of LiIon batteries.
From little of what know from about them, LifePo4 seems to be chemically more stable, unlike LiIon batteries which are subject to thermal runaway, probably make better sense to put them in vehicles versus LiIon. Unfortunately, I don’t think LifePo4 don’t have as much capacity as LiIon I think, and if you drain them completely, they become expensive paperweights. To be honest, I know nothing about battery technology. But, I’ve been exploring ways to reduce weight in my miata, so I learned about LiFePO4. I stuck this 2.8 lb motorcycle battery
…. to replace this battery 28 lb battery that was already smaller than a standard size one ….
The nice thing, is it’s tiny enough and weighs so little that I can move the battery from the trunk to sit right behind my passenger seat next to the ECU….
I was curious why Tesla or Boeing for that matter decided to go with LiIon instead of LiFePO4… But then again, I’m sure there is a good reason for it so, I won’t second guess the experts in the field on this.
