Abstract:
Disclosed is an external charging method for a vehicle, comprising: a charging/discharging controller detects a connection signal of a discharge gun; after a BMS receives a discharge enabling signal, the BMS controls a high-voltage distribution box to enable a battery pack to release direct current; after receiving the connection signal and the discharge enabling signal, the charging/discharging controller detects whether a first signal of the discharge gun is a first rated value, and when the first signal is the preset first rated value, the charging/discharging controller sends a second signal to a charging vehicle; when the first signal is changed from the first rated value to a preset second rated value, the charging/discharging controller converts the direct current released by the battery pack into alternating current to charge the charging vehicle.
