But if you are talking about faster partial-capacity refills during road trip stops, we already have that.
Current batteries charge way faster from 0-50% than 50-100%. The curve really starts to fall off above 80%.
I usually try to plan my stops so that I’m arriving with 5-10% and charging to 60-65%. With 250kW chargers that results in a ~15min charging stop.
I don’t think the costs of development, impact to vehicle design, and infrastructure would make sense for swaps just to replace what is already a 15min charge.
- toss1 5y agoTrue, the differential will reduce as we get even higher-amperage chargers and batteries w/higher C ratings. Yet still, being able to get 40% in 3 minutes is still better. I'd also see little reason that a properly configured trunk couldn't hold a pair of 40% battery units. Kind of like carrying jerry-cans on the back of a rover, except you can just plug them in...
