UNINTERRUPTED ALTERNATING CURRENT CHARGING CONTROL METHOD FOR PURE ELECTRIC VEHICLE AND ELECTRIC VEHICLE

摘要

An uninterrupted alternating current charging control method for a pure electric vehicle, and an electric vehicle, the uninterrupted alternating current charging control method for the pure electric vehicle comprising: simultaneously waking up, by means of an on-board charger, battery management systems in a plurality of battery packs connected in parallel on a bus; reading, by means of a vehicle control unit, state information about each of the battery packs from the bus and determining whether each of the battery packs meets a charging condition according to the state information about each of the battery packs; and sequentially charging each of the battery packs according to a preset charging sequence of the battery packs. An alternating current charging technique is applied to the pure electric vehicle having multiple power sources; in the charging process, in order to satisfy the user experience, alternating current charging is performed on the plurality of power battery packs in sequence without re-plugging a charging gun by means of signal interaction between the OBC (on-board charger), the VCU (vehicle control unit) and the BMS (battery management system) of each of the battery packs.
