Abstract

The invention relates to the technical field of testing and discloses a bidirectional charge-discharge motor controller testing system and method. The bidirectional charge-discharge motor controller testing system comprises a testing host computer, a simulator, and a bidirectional charge-discharge motor controller. The testing host computer is connected with the simulator and is used for transferring simulating models to the simulator, wherein the simulating models include a power grid model, a bidirectional charge-discharge motor model, and a battery module. The simulator is in communication connection with the bidirectional charge-discharge motor controller. The bidirectional charge-discharge motor controller, the power grid model, the bidirectional charge-discharge motor model, and the battery model form a closed-loop operation testing circuit. The simulator is used for acquiring the operation data of the bidirectional charge-discharge motor controller, sending the acquired operation data to the testing host computer, and sending simulating signals to the bidirectional charge-discharge motor controller. The invention further provides a bidirectional charge-discharge motor controller testing method. The bidirectional charge-discharge motor controller testing system and method may easily test the bidirectional charge-discharge motor controller, increase testing efficiency, and reduce testing cost.

Description

technical field

[0001] The invention relates to the technical field of testing, in particular to a testing system and method for a bidirectional charging and discharging motor controller. Background technique

[0002] At present, most electric vehicles get electricity through charging piles, and cannot feed back the electricity in the car battery to the grid. However, with the gradual increase in the production and sales of electric vehicles, the use of electric vehicles will increase. Since most EVs spend an average of 95 percent of their time parked, each vehicle could add a lot of value if their batteries could feed power to the grid. V2G (abbreviation of Vihecle to grid, electric vehicle to grid two-way charging and discharging) technology is to return the excess power in the electric vehicle battery to the grid (called grid connection). In this way, when the car is idle, the excess electric energy can be returned to the grid for annual energy dispatching, and the peak...
