Title:

ELECTRIC VEHICLE POWER SUPPLY, ELECTRIC VEHICLE, AND OPERATION METHOD FOR ELECTRIC VEHICLE POWER SUPPLY

Document Type and Number:

WIPO Patent Application WO/2023/125646

Kind Code:

A1

Abstract:

An electric vehicle power supply, comprising: a battery pack, a bidirectional direct-current conversion apparatus, a controller and a data acquisition module, wherein the controller is separately connected to the data acquisition module, the bidirectional direct-current conversion apparatus and an electric vehicle motor; the bidirectional direct-current conversion apparatus is further connected to the battery pack; the controller determines a voltage conversion mode of the bidirectional direct-current conversion apparatus according to an operation signal acquired by the data acquisition module; the bidirectional direct-current conversion apparatus boosts an output voltage of the battery pack during forward conversion, and transmits the boosted output voltage to the electric vehicle motor by means of the controller; and during reverse conversion, the bidirectional direct-current conversion apparatus charges the battery pack by using a back electromotive force generated by the electric vehicle motor. According to the electric vehicle power supply, the bidirectional direct-current conversion apparatus is provided so that the back electromotive force generated by the electric vehicle motor can be used for charging the battery pack, and the cruising ability of the electric vehicle power supply is improved. Also disclosed are an electric vehicle and an operation method for an electric vehicle power supply.
