Any reason they can't just route the current generated when battery is full to a big resistor/heatsink?

That would seem to avoid the problem of changing braking dynamics, and potentially save wear on friction brake components (pads, discs, etc)...




It's kind of a lot of power (hundreds of kilowatts for a panic stop from 60mph), so a reliable resistor bank would probably add more weight/bulk than it buys in reduced brake wear.


it's not really about the reduced brake wear so much as avoiding the sudden change in stopping distance when the battery stops charging.
