Braking energy recovery experiment table for composite energy system of electric vehicle and recovery method of braking energy recovery experiment table

The invention discloses an electric vehicle composite energy system braking energy recovery experiment table and a recovery method thereof. The recovery experiment table comprises a braking energy recovery module and a signal processing module. The braking energy recovery module comprises a flywheel used for simulating the running inertia of a vehicle, a three-phase asynchronous motor, a magnetic powder brake, a motor, a motor controller, a super capacitor, a power battery and two relays used for controlling on-off of branches. The signal processing module comprises a single-chip microcomputer controller used for data processing. The single-chip microcomputer controller obtains analog signals of the super capacitor and the power battery and rotating speed signals of the flywheel, processes input data and transmits the processed data to the two relays. And the on-off frequency is controlled so as to control the distribution of braking energy between the super capacitor and the power battery. The service life o
