Circuit for electric vehicle? Regenerative braking / free-wheeling?
S1 closed and S2 open to accelerate the vehicle.
S1 open and S2 closed to recharge the batteries while freewheeling down hill.
Batteries: sealed lead acid batteries 12V or 24V (depending on motor)
Motor: brushed DC motor
Would this kind of circuit work? Is it possible to recharge SLA batteries in such a way?
Any help and/or suggestions is appreciated.
PS. I know it would also be possible to implement regen braking using a full H-bridge, but i think we would be doing more freewheeling than braking on the race track.
