An alternating-current charging electronic lock control system of an electric automobile comprises a battery management system, a vehicle-mounted charger, a vehicle control unit, an electronic lock, abattery pack and a DCDC, the battery management system is in signal connection with the vehicle-mounted charger, the vehicle control unit, the battery pack and an instrument, and the vehicle controlunit is in signal connection with the instrument and the DCDC. The electronic lock is in signal connection with the battery management system or the vehicle-mounted charger, the positive electrode ofthe battery pack is electrically connected with the positive electrode end of the discharge interface through the main positive relay, the negative electrode of the battery pack is electrically connected with the negative electrode end of the discharge interface through the current sensor and the main negative relay, and the positive electrode of the battery pack is electrically connected with theslow charge interface through the slow charge relay and the vehicle-mounted charger. The negative electrode of the battery pack is electrically connected with the slow charging interface through thecurrent sensor, the main negative relay and the vehicle-mounted charger, and the main positive relay, the current sensor, the main negative relay and the slow charging relay are all in signal connection with the battery management system. According to the design, the controllability of the locking and unlocking processes of the electronic lock can be ensured.
Description
technical field [0001] The invention relates to the technical field of battery charging and discharging, in particular to an electric vehicle AC charging electronic lock control system and a control method thereof, which are mainly suitable for ensuring the controllability of the locking and unlocking process of the electronic lock. Background technique [0002] The battery management system (BMS) is an important link connecting the power battery with other controllers and charging systems (on-board charger or off-board charger). AC slow charging process control is one of the important functions of BMS. "GB / T20234.1-2015 Connecting Devices for Conductive Charging of Electric Vehicles Part 1: General Requirements" stipulates that the charging interface should have a locking function to prevent accidental disconnection during charging, so the AC charging interface of electric vehicles must be With locking device. The electronic lock of the AC charging port is usually controll...
