Hi all,
I’ve built a small cart powered by two hub (BOT) wheels, each driven by its own ODrive S1. The system is normally powered by a 24 V Greenworks Li-ion battery (link). Regenerative energy from the wheels is fed back into the battery.
However, I’m curious what happens when the battery is disconnected, but the cart is still moved (pushed by hand), causing the wheels to spin and generate energy.
Where does the regenerative energy go in this case?
Is it potentially harmful to the ODrives if there’s no sink (like a battery or brake resistor) for that energy?
Thanks in advance for any clarification or advice!
