The invention discloses a charge and discharge control system, method and device, control equipment, and computer storage medium. The charge and discharge control system includes a bidirectional charging device and a processing module; the bidirectional charging device includes sequentially connected AC connectors . A first bidirectional AC / DC conversion module and an energy storage and voltage stabilization module; the processing module is connected to the first bidirectional AC / DC conversion module, and the processing module where it is located does not directly stop the first bidirectional AC / DC conversion module when it receives a discharge stop instruction. A bidirectional AC / DC conversion module stops working, but opens its reverse function, that is, the functional mode of the first bidirectional AC / DC conversion module is switched from the original direct current to alternating current functional mode to the alternating current to direct current functional mode. The residual energy of the AC connector is transferred to the energy storage and voltage stabilization module, which can ensure that the voltage of the AC connector drops rapidly, and can avoid personal safety hazards such as accidental electric shock caused by the residual voltage of the AC connector after the discharge is completed.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a bidirectional charger, an external discharge method thereof, and a new energy vehicle including the bidirectional charger. Background technique [0002] The traditional charger converts the alternating current of the grid into direct current to charge the power battery, and the energy conversion is one-way transmission. Compared with the traditional one-way energy transfer, the two-way charger is gradually developing into a two-way charger. The two-way charger adds the function of external discharge on the basis of the traditional one-way charging function. The two-way charger can realize the two-way transmission of energy conversion, so that the electric vehicle can become an energy supply device for external discharge, realize the distributed grid-connected discharge (V2G, Vehicle to Grid) of peak and valley adjustment, and vehicle-to-vehicle Emergency rescue discharge (...
