"Faster rate of recharge (minutes rather than hours)" sounds like a big win for some applications.
It's such a shame that these batteries are so heavy, because IMHO fast recharge is one of the things still holding back electric car adoption. Even the Tesla fast-charge stations take 30-40 min to reach 80% charge, while a gasoline-powered car can hit 100% in only a minute or two.
(Though OTOH, I've always been surprised that fleet vehicles like city buses can't surmount that issue with modular battery backs that can be physically swapped out at the terminal stop and then charged offline before swapping back into another bus...)
- mulmen 10y agoTransit hubs could even have the charging infrastructure onsite but in that case why not just swap the whole bus?
- robotresearcher 10y agoBecause then you have an empty bus while it charges.
- mulmen 10y agoI guess it depends on how hard it is to swap out a battery but on a vehicle like a bus that can probably be made very simple. Now that I think about it a bus must carry a large quantity of fuel, I wonder how long it takes to fill one up. Swapping a battery could actually be faster.
- sitkack 10y agoI borrowed and electric car for a week, charging overnight on a 15 amp circuit. And occasionally on a middle and top end circuits as a test. Charge times come into play when you dont own your home or easily have a way to run power to your car. That is it. I don't think is the biggest blocker, cost is the blocker.
