Hello to all!
I am interested in building an all electric go kart and i have been thinking about different features that it could have and i came across regenerative braking. The motor I will be using is a 48V 1kW DC motor. While I do have some experience with electronics, I have no clue about how stuff in the car industry works. For example should I take 4 smaller 12V batteries to match the 48V and simply PWM or should I take one bigger 12V battery and use a step up converter? Because a car battery has more than 12V and I don't know if the motor can handle this overvoltage. The one thing that concerns me most though, is how I could implement regen. braking. Because if I would connect 4 batteries and then just feed the current back to the battery it wouldn't work, because of the batteries higher voltage, right? Or if i use one battery and step down the 48V to 12V it wouldn't work for the same reason, or am I wrong?
Please share any experience you have with me!
Thanks in advance
