My i3 is easily the best and most fun car I’ve ever owned.
It is a little rocket ship that seems capable of reaching orbital velocity.
I like the single-pedal driving a lot. It is simply safer and less stressful to drive this way.
Although, there is always room for improvement.
When the battery is full or it is cold out the regenerative braking is greatly reduced and I have to modify my style of driving.
Could supercapacitors be used to correct this? They are not affected by ambient temperature.
The implementation would be something like this:
1. The supercapacitors would not charge up during charging.
2. The power from regenerative braking would be directed to the supercapacitors first and only to the battery if the caps are full.
3. The motor would always deplete the caps first before pulling power from the HV battery.
Since the discharge rate of supercapacitors is far higher than lithium-ion batteries, it should be possible to supply the motor with greater power for short periods of acceleration.
