How would you Tesla drivers like to have total dedicated control over your regen braking. ie a third pedal next to the brake pedal in the same place a clutch pedal would be. As impossible as this would be to actually install in a Model S we are only hypothesising about having the ability to control regen on command from zero to about 150kW. So the existing regen up to 50kW when the throttle is released is decommissioned and the car basically coasts or angel gears when the throttle is released. Then when the third or regen pedal is pushed, you can modulate it up to max as far as the traction control will allow. The regen pedal will feel exactly like a brake pedal with a short firm stroke. The dedicated regen system could also be built into the existing brake system leaving still only 2 pedals. Below is a shot of a dedicated regen pedal I built for my Barina conversion, was actually a 4th pedal as It had a 5 speed manual transmission with the clutch still in use. Its a motorcycle front brake lever with a pressure transducer screwed into it. The transducer converts hydraulic pressure (0-200psi) into an electrical signal (0-5v). My previous EV conversion, a Daihatsu Mira also had this system and it was used all the time and accounted for 27% of the cars range making it the worlds most efficient passenger electric vehicle conversion regularly clocking consumtion figures as low as 80Wh/km. A Mitsubishi I-Miev can do 116Wh/km and the SunSwift carbon fibre Solar racer could do 35Wh/km. So let us know what you think not that its going to change anything.
