The application discloses a charging control device, method, and electric vehicle, including:
A signal processing module, configured to receive a first control guide signal sent by the power supply device, and send a high-level signal of the target duration to the wake-up module according to the first control guide signal;
The wake-up module is used to wake up the battery management system after the duration of receiving the high-level signal reaches the target duration.
The patent summary shows that with this charging control device, even if there is a power outage during the charging process, there is no need to re-plug the charging gun or restart the electric vehicle/charging pile . The charging control device only needs to receive any CP signal again. The battery management system can be awakened by the high-level signal of the target duration, and the charging can be continued.
