Abstract

The present invention relates to a charging control method and apparatus, a vehicle-mounted charging device, and a vehicle, the method includes: determining a target proprietary protocol chip corresponding to a device parameter of a device to be charged; triggering an initialization of a power chip in the charging device based on a comparison between a currently running charging protocol of a charging device and a target charging protocol to change the currently running charging protocol to the target charging protocol; acquiring status information of the power chip; triggering the charging device to charge the device to be charged using the target proprietary protocol chip after the status information indicates that the initialization of the power chip has been completed. This method ensures that the charging device is triggered to charge the device to be charged only after the power chip has completed the initialization, preventing the charging device from generating a runaway current and thus avoiding damage to the proprietary protocol chip from the runaway current.
