if i understand regen correctly, when i take my foot off of the accelerator my phev reverses the motor making it a generator and charges the battery. the dial shows “mild” regen. at moderate to highway speed if i then step on the brake i’ll get strong regen. i would expect the regen to vary with the speed of the tires turning the motor/generator so how does pressing the brake pedal increase the regen? and what is strong regen, higher voltage? thx.....
