Abstract

The embodiment of the invention provides a vehicle-mounted battery management system and method. The vehicle-mounted battery management system comprises a vehicle-mounted battery, a battery managementmodule connected with the vehicle-mounted battery and a generator connected with the vehicle-mounted battery, the vehicle-mounted battery is used for supplying power to a vehicle starter and / or a vehicle-mounted electric appliance; the battery management module is used for acquiring the battery capacity of the vehicle-mounted battery; and a vehicle engine is started to drive the generator to charge the vehicle-mounted battery under the condition that the vehicle engine is not in a working state and the difference value between the battery electric quantity and the starting electric quantity of the vehicle starter is not greater than a starting threshold value. By means of the vehicle-mounted battery management system and method, the generator can be started to supplement power to the vehicle-mounted battery when the electric quantity of the vehicle-mounted battery is low, and the situation that the vehicle starter cannot be started due to the fact that the electric quantity of the vehicle-mounted battery is exhausted is avoided.

Description

technical field [0001] The embodiments of this specification relate to the technical field of power supplies, and in particular to a vehicle battery management system and method. Background technique [0002] In practical applications, the on-board battery in the car has become an indispensable module. The on-board battery stores electricity generated by the car's alternator and supplies power to the vehicle's starter to start the car. In addition, the on-board battery can also assist the generator to supply power to the electrical appliances on the car, so as to ensure the normal operation of the car. [0003] When the car is turned off, that is, when the car engine is not working, the generator driven by the engine in the car is also not working. At this time, the electrical appliances in the car are mainly powered by the car battery, which gradually consumes the car battery. in the power. Even if the electrical appliances in the car are not in working condition, due to...
