Circuit for electric vehicle? Regenerative braking / free-wheeling? Answered
I'm working on a circuit for an electric trike I plan to build for the local EV challenge competition. I plan to incorporate regenerative "free-wheeling" to recharge the batteries on the down hill sections.
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.
