What electric vehicles need is slide in battery packs, you pull into a service station and the robot slides out your battery and slides in a fully charged one. They charge you for the amphours used in the battery removed. Larger vehicles might get 2, 3, 4 or more batteries. Chris
Probably do better in fleet service.
Many fleets of port container tractors, airplane tow trucks, etc., do use that strategy.
The problem for private cars is each station would have to stock hundreds of models of batteries for each make and model.
Why don't cars standarize battery packs? Perhaps, but in their argument, each pack has to be shaped around their chassis for performance, space, and crash protection.
For instance, be really hard to share a pack between a Corvette and Nissan Altima, even though the cars are the same weight class.
Yah that makes sense.
As well, some manufacturers liquid cool and some air cool their packs. As well some use different chemistries. I think there would have to be a lot of collaboration. Don’t see it happening in the short term.
The same thing happens with DC fast charging. There is CCS (European) Chademo (Japanese and some Korean) and Tesla. Tesla with the right adapters can use CCS (European models) and Chademo (some American models) but nobody has adapted to Tesla even though it is open source and patent. Chevy has gone CCS.
At least everybody got together on level 2 charging. Everybody uses J1772 although Tesla uses a small physical adapter. Comes with the car.
Non Tesla’s can also use Tesla level 2 chargers by purchasing an adapter but they are like 150 bucks. (We have one, works well).
I think their will be more collaboration on both physical and protocol formats in the next 10 years.
