Abstract

The invention discloses a control method and system for preventing insufficient voltage of a whole-vehicle storage battery. The method comprises the following steps: acquiring battery voltage when a vehicle stops; if the battery voltage is lower than or equal to a voltage threshold, sending the battery voltage, a whole-vehicle state, the life of the storage battery and start current to an information processing platform; acquiring the standing time length of the battery by the information processing platform according to the received battery voltage, whole-vehicle state, life of the storage battery and start current and historical power consumption data of a current user; informing the user of the standing time length of the current battery. By adopting the control method and system provided by the invention, the user can be informed of the standing time length of the current battery so as to charge the vehicle in time and prevent insufficient voltage of the storage battery.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a control method and system for preventing power loss of a vehicle battery. Background technique [0002] The car battery is installed in the engine compartment, which is a device that converts chemical energy into electrical energy, and belongs to the DC power supply. When starting the engine, it provides a strong starting current to the starter; when the generator is overloaded, it can assist the generator to supply power to the electrical equipment. The battery is also a large-capacity capacitor, which can protect the electrical appliances of the car; when the terminal voltage of the generator is higher than the electromotive force of the lead-acid battery, a part of the electrical energy is converted into chemical energy and stored, that is, it is charged. The car battery is the first and necessary condition to ensure the operation of the whole car. It allow...
