Abstract

The application discloses a charging control device and method and an electric vehicle. The device includes: a signal processing module, configured to receive a first control guide signal sent by a power supply apparatus, and send a high-level signal of a target duration to the wake-up module according to the first control guide signal; and a wake-up module used to wake up a battery management system after the duration of receiving the high-level signal reaches the target duration. Even if the power is turned on again after a power failure during the charging process, there is no need to re-plug a charging gun or restart an electric vehicle / charging pile at a charging port. 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 charging can be continued.

Description

technical field [0001] The present application relates to the field of electric vehicle charging, in particular to a charging control device, method and electric vehicle. Background technique [0002] With the development of the economy, electric vehicles are increasingly becoming electronic products, and the demand for intelligent and green electric vehicles is getting higher and higher. At present, when an electric vehicle on the market is plugged into a charging cable and is not being charged, the battery management system (BMS) of the electric vehicle will enter a dormant state. After the BMS enters the dormant state, the control pilot (CP) signal sent by the power supply equipment (such as charging pile, etc.) cannot directly wake up the BMS, and the BMS must be re-inserted at the scene or restart the electric vehicle to wake up the BMS. In order to further charge the power battery of the electric vehicle through the BMS. [0003] Since manual on-site operations are r...
