The invention discloses a charging control circuit and control method for a vehicle-mounted low-voltage controller, and the control circuit comprises a vehicle-mounted low-voltage storage battery, a charging drive circuit, and the vehicle-mounted low-voltage controller, and the vehicle-mounted low-voltage storage battery is connected with the low-voltage controller through the charging drive circuit. An auxiliary power supply of the charging pile is connected to the charging drive circuit through the charging port, and the charging drive circuit controls whether the vehicle-mounted low-voltagestorage battery supplies power to the vehicle-mounted low-voltage controller according to the input auxiliary power supply of the charging pile. The charging control circuit has the advantages that power is supplied to the vehicle-mounted low-voltage controller through the added low-voltage storage battery, isolation and automatic power supply during whole vehicle charging are achieved through the relay and the anti-reverse diode, the structure is simple and reliable, the ablation risk of the vehicle-mounted low-voltage controller in the prior art cannot be generated. And the low-voltage storage battery can be charged for preventing power shortage.
