And why dont your disc brakes convert heat and friction energy to support battery capacity? The mechanical brakes on a bike can easily overpower a motor if for some reason you were to throttle and brake at the same time. When you are actually cruising downhill and pushing current back into the battery there is a lot of heat generated within the battery itself. Do you have any questions about this topic? Hitting the brakes on a car creates kinetic energy. Hybrid and electric vehicles typically use these types of brakes. Since we launched in 2006, our articles have been read billions of times.
