The invention provides an electronic mechanical braking system, a wheel end braking device and an electric vehicle. The electronic mechanical braking system comprises two central controllers and four wheel end braking devices. Wherein the two central controllers are in one-to-one correspondence with the two brake pedal sensors, each central controller is used for receiving a brake pedal signal output by the corresponding brake pedal sensor, and the brake pedal signal is used for indicating the motion state of a brake pedal. The four wheel end braking devices are used for outputting braking force to brake the electric vehicle. According to the electronic mechanical brake system provided by the invention, the two brake pedal sensors and the two central controllers are arranged, so that the brake control redundancy of the electric vehicle is realized; the electronic mechanical braking system can still accurately brake the electric vehicle, so that the braking safety and reliability of the electronic mechanical b
