Just for fun. How do you feel about having a virtual set of gears to shift/paddle your way through in an EV?
Here's my thoughts:
The virtual transmission would use a combination of Motor RPM, Power Output and Regen Levels to simulate gears and (this is where it might go off the rails) the torque curve of a naturally aspirated ICE.
So for example :
1st Gear (V1 displayed on the dash cluster if your particular EV happens to include one) is responsible for say 0 - 35mph . With your foot on the floor, the motor controller creates a fake power curve that exhausts near the end of the virtual gear or as the vehicle approaches 35mph and it's pretend redline/rev limiter. Having perceived you are running out of fake power, you shift or paddle into V2.
2st Gear V2 sends full (ramped) power back to the motor and it pulls until nearing 60mph as the power virtually exhausts yet again. You can do this through any number of artificial gears sliced out of the true spectrum of the EV drivetrain.
Downshifts:
A downshift will produce max regen at the top of the virtual gears speed/rpm range and will diminish as it decelerates to the lower end to simulate engine breaking. A downshift outside of the virtual gear range will produce an error tone just like automatics with a sport shift feature do.
Obviously this serves NO purpose for efficiency or max performance and would actually hurt both but I think it would be entertaining if implemented well.
