See, Apple? Even cars can do it :)

At the moment my two biggest fears against buying an EV is it catching fire in my garage and it dying after 5 years then having to buy a 30k battery. Once technology advances that doesn't happen I will buy and I would love your plan. Why can't this be a stop gap?

It already doesn’t happen.

while there have been fires and they do burn hot and self oxidize, it’s more rare than for ICE cars and usually caused by physical damage.
my EV battery is warranted for 8 years, 100k miles, and some are higher
my Tesla battery could be replaced for $15k, and it’s been decreasing over time, so half what you fear
batteries usually don’t just die: end of life is usually set at 70% health, meaning you can keep using it with reduced range

Swappable batteries can’t be a stop gap because it would require a huge infrastructure buildout over many years that would become a lost investment, versus technology that’s already here and improving every year. Starting from scratch with swap stations, vehicle design, industry standards, vs hundreds of thousands of charging stations already deployed.

If you think chargers aren’t available enough or expanding enough, consider that they’re known technology, relatively cheap, installable by any electrician, using a national power infrastructure that already exists. Installing a level 2 charger at my house was equivalent to a new stove circuit. I mean I agree we need to speed up the buildout, but think how cheap and easy these are compared to developing an entire new infrastructure from scratch. How simple a ”plug” is compared to a robot that can handle a one ton battery. How long it took to standardize an effing plug, compared to standardizing entire battery packs. How can anyone think this would go faster?

I looked more into fires and battery replacement and agree with your stats, much appreciated for the info.

However, I never said it swappable would be faster for expanding. I said it was safer and allow for battery integrity evaluation. I agree the ideal solution would be chargers in homes as long as battery health and saftey are reasonable which they already reaching that point.

I see alot of talk in these threads about how bad it would be to make infrastructure and need to invest. But our current infrastructure didn't just show up. I bet when the first cars came out people with horses said the same thing. Thinking how much it would cost to build all these gas stations and refineries. Investment will have to happen and EV is the future. Obviously home chargers are cheaper and again the ideal solution as technology advances and the grid can keep up.
