Problems solved by technology
[0006] The purpose of the present invention is to solve the limitations of the use scene of electric braking brought by the power battery. It can not be used when it is moving, which seriously affects the consistency and smoothness of the driver's driving of the vehicle. A pure electric vehicle electric braking energy recovery device is proposed. When the power battery is not allowed to be charged, the electric brake can still be used to brake the vehicle, and the electric energy generated by the brake can be used again to drive the vehicle, which will not bring the risk of overcharging and over-discharging to the power battery

The invention discloses an electric brake energy recovery device for a pure electric vehicle. The energy recovery vehicle comprises a whole vehicle controller, a BMS, a power battery, an MCU, a brakepedal module, an accelerator pedal module, a super capacitor, a contactor KM1 and a contactor KM2. The BMS and the MCU are respectively connected with the whole vehicle controller through CAN wires. The BMS is a battery management system, the MCU is a motor controller, the power battery and the super capacitor are connected with the BMS through CAN wires, and the brake pedal module and the accelerator pedal module are connected with the whole vehicle controller through hard wires. The beneficial effects are that: electric braking is ensured to be always online; the consistency and the smoothness of vehicle driving are maintained; it is ensured that the vehicle braking state is not interfered by the state of a power battery; and the driving safety is improved. The power battery is protectedfrom the risk of overcharging and overdischarging, the safety of the battery is maintained, the service life of the battery is prolonged, and great benefits are brought to application and popularization of new energy vehicles.
Description
technical field [0001] The invention relates to an energy recovery device, in particular to an electric braking energy recovery device for a pure electric vehicle, and belongs to the application technical field of the electric braking energy recovery device. Background technique [0002] A pure electric vehicle is a vehicle that uses a power battery as a power source for energy storage. It uses a power battery as a power source for energy storage, and supplies electric energy to the motor through the battery to drive the motor to run, thereby driving the car. [0003] Electric braking means that the MCU receives instructions from the vehicle controller to reduce the rotation frequency of the stator magnetic field. Due to inertia, the rotor still rotates at the original speed. When the rotor speed of the motor exceeds the rotation speed of the synchronous magnetic field of the motor, the direction in which the rotor cuts the magnetic field line is reversed, and the electroma...
