You familiar with this chink EV company?

For years now, I've wondered why no one has addressed the achille's heel of EVs, which is charge time. The obvious solution is interchangeable battery packs.

Leave it to the slopes to bring one to market. Kind of surprised that Elon didn't bring this to market a while ago. Was thinking of moving a little bit of my 401K there.....while I still have one.

Interchangeable packs has a number of benefits besides less than 5 minutes to "recharge". It allows for variable size packs.

Why carry around 300 miles worth of battery if you are driving 3 miles to the grocery store?

Also, according to their website, Nio never charges their packs to 100% full. They stop at 90% which lengthens cell life a good bit. I assume this also applies to how far they run them down.

I own some of their stock as does (did) Mikey. So yeah great company, made me a ton of $$$.

NIO has been rolling this out for a few years now IIRC. Ellen was going to do it too up until 8 or 10 years ago but nixed it for some reason. Maybe too complicated logistically or something. And yeah I bought some NIO stock a couple of years ago but unfortunately didn’t sell when I should have. Still holding it and just a little better than break even at this point. Still hopeful though.

The charging thing still is a problem, for some, and I’m not sure if the swapping thing is the answer or not. Most of the newer models are coming out with higher DC charging voltage capabilities, which greatly decreases the charging time. I think the new Hyundais can handle 800V, at least twice the voltage of most others and can go to 80% capacity in something like 20 minutes. Not like pumping gas but getting better. I know my F250 took almost that long to fill.

I’m thinking that having multiple interchangeable battery sizes is not such a good idea. Those things are pretty heavy and if you start fooling around with it you’re going to change the dynamics of braking, handling and all sorts of other stuff. Batteries are being built right into the chassis to keep a low center of gravity, which really improves the handling.

As far as charging to 80, 90 or 100%, I know that Hyundai already limits it. If you have a car that’s rated at, say 300 miles, the actual capacity would be 330 or more but the controller won’t let you go higher. It’s already built in. I charge mine at home after midnight. I never drain it all the way down, but my level 2 charger will add 30 miles for each hour I have it plugged in.

The Ioniq 5 will go from 10% to 80% in 18 minutes at a 350 kW charging station.
