The increase rpm of a motor may happen while not pressing on the accelerator, is when I coasting down a hill with the transmission in gear. When I was working, my daily trip was a 10.4 miles around trip to work each day. The road was a roller coaster type which has a 3 mile mild up slope and than a very steep 2 miles at the end of the hill.
This was with a battery pack that weigh 3000 lbs of 300 ah batteries charge up to 252 volts. I could get up to 70 mph on the gentile roller coaster 3 mile approach to the last 2 miles, and maintain the same accelerator pressure up this hill which would slow to 35 mph which was the right speed to inner the exit. Coming down this hill, I allow the motor to get up to 6000 rpm going down the first 2 miles getting up to 85 mph which develops enough inertial to propelled the EV for the next 3 miles right into my garage without any additional power from the motor controller.

I wonder why this would be.
