The brake mechanism of electric vehicles

Most electric cars only need one leg to control, rarely use the brake and when you let go of the accelerator, the car will slow down and stop completely.

Answer the question “How do electric cars without engine brakes fall?” With the experience of someone who worked at Tesla, Fremont for 10 years I can explain the following.

Regenerative braking is an energy recovery mechanism that slows a moving vehicle or object by converting its kinetic energy into a form that can be used immediately or stored until needed. In this mechanism, the electric traction motor uses the vehicle’s momentum to recover energy that would otherwise be lost to the brake disc as heat.

This is in contrast to conventional braking systems, in which excess kinetic energy is converted into unwanted heat and is wasted by friction in the brakes or with dynamic brakes, where energy is recovered using dynamism. electromechanical makes a generator but is immediately dissipated as heat in the resistor. In addition to improving the vehicle’s overall performance, regeneration can significantly extend the life of the brakes as mechanical parts will not wear out very quickly.

In electric cars, use less brakes and when you let go of the accelerator the car will slow down and stop completely, better than traditional gear brakes. It is worth noting that if an electric car can travel 600 km at a speed of 100 km / h, it will be able to run to 900-1,000 km or more at speeds of 50-60 km / h or less.

Hope the above will help you understand more about electric cars.
