Hot swappable EV batteries would be cool
Exists, Nio does it and is steadily expanding the network, but with how fast the 800v cars are charging it’s not really a problem anymore. I took longer breaks on roadtrips than my ev needs to charge even when I still drove a diesel.
If the battery is not easily swappable, then your green EV is a rolling pile of premature waste by design. Not intended to be drivable for 20 years, living a long life on the used car market (as is common with ICE cars), but instead diverting prematurely to waste in a nicely profitable way.
Actually, the batteries are proving to be extremely reliable, to the point that they’re likely to outlast the rest of the vehicle. On average, batteries with 100,000 miles are still at 90% of their initial capacity. The situation will only get better as solid state batteries are rolled out
I am really looking forward to those new battery developments. I still think the EV industry needs to focus on serviceability. I strongly believe in right to repair, and vehicles that are designed to require disassembling most of the car to replace a battery is simply anti-consumer design philosophy.
I don’t think this really caught on because not everyone takes care of their batteries to the same degree. Frequently charging to 100% or draining to 0% has some negative impacts reducing range and performance. You’re likely to receive one of these used batteries in your car with a swap.
Imagine doing an engine swap on an ICE vehicle with a used one that never had an oil change.
But you could swap whenever. Bad battery? Swap it.
The real difficulty is making the process work across multiple vehicles, making it safe and making it less of a pain than DC charging.
This is what is needed. Serviceable by design, with ease.
Roadways that charge your vehicle as you drive on them would be even cooler
Imagine a vehicle that’s fully autonomous, always connected to power, and can carry more than 4-6 people at a time.
You could allocate lanes specifically for it, too, so it could go super-fast.
We wouldn’t need nearly as much parking, so you could push things closer together and be able to walk to places, and have parks…
Man, that’d be cool. I bet if it ever becomes possible, America will be the first to do it at scale. It would be such a technological and societal advantage, we’d be dumb to not use it to its fullest potential.
Edit:
If only it existed! We could call it a RAIN, for how it cascades people upon a location like rainfall. Or maybe to clarify that it’s for transportation… a T-RAIN? Man, if only… /s
At first read I thought you meant swap vehicles while traveling. With how auto manufacturers are moving towards subscription-based models, I wouldn't be surprised if something like that becomes an option. $700/month hot-swappable Ford Fiesta EV's. Drive one in, take another out, carry on your route.
Or just turn every road into a railroad and switch out cars for trains.
Choot choot!
Gasoline is based.
I like the smell of gas. Its impact on the environment, not so much.
I know better not to smell gas. Climate change is not man made.
Oh you’re one of those, ew
