The invention discloses a method, a device and a system for controlling charging of a power battery. The method comprises the following steps: judging whether high-voltage load in an electric automobile is in a power consumption state when determining that a power battery charging system is connected to an external power supply and the power battery does not need to be charged; controlling a first switch assembly between a charger and the high-voltage load to be closed and controlling a second switch assembly between the charger and the power battery to be switched off if the high-voltage load in an electric automobile is in power consumption state, and enabling the charger to supply power to the high-voltage load by using the external power supply. Through the method, the device and the system for controlling charging of the power battery, the power source of the high-voltage load in the electric automobile can be flexibly controlled when the power battery is connected to the external power supply; the method, the device and the system can ensure that the power of the power battery is in a full state after the charging is completed; the endurance time of the power battery is prolonged; the reliable travel of the user is ensured.
Description
technical field [0001] The present application relates to the field of electric vehicles, in particular to a power battery charging control method, device and system. Background technique [0002] Recently, with the rapid development of the automobile industry, low-carbon, energy-saving and emission reduction have become the core competitiveness of automobile technology. Electric vehicles, with their green and environmentally friendly features, occupy an increasing proportion in the entire automobile field. Electric vehicles mainly rely on power batteries to provide power, and various electrical equipment in electric vehicles also rely on power batteries to provide energy. [0003] At present, during the charging process of the power battery, the high-voltage accessories in the car, such as air conditioners and DC power supplies, may still use the energy of the power battery, which makes the power battery likely to appear "float charge" after charging. It will affect the se...
