Abstract

The invention relates to a method for detecting circuit opening of a storage battery pack. The method comprises the following steps of obtaining the battery voltage of a preset battery number in the storage battery pack, and the circuit opening voltage of the single storage battery; according to the preset battery number and the battery voltage of the preset battery number, calculating the average battery voltage; judging whether the average battery voltage is smaller than the circuit opening voltage or not; when the average battery voltage is smaller than the circuit opening voltage, delaying preset time; after the preset time is delayed, judging whether the average battery voltage is smaller than the circuit opening voltage or not, wherein when the average battery voltage is smaller than the circuit opening voltage, each storage battery in the preset battery number has a circuit opening fault. The method for detecting the circuit opening of the storage battery pack has the advantages that the detection efficiency is high, the circuit opening fault of one storage battery in the storage battery pack can be timely and quickly detected, and the safety hidden hazards caused by the circuit opening problem of the storage battery can be prevented and solved.

Description

technical field [0001] The invention relates to the field of storage battery technology, in particular to a method for detecting an open circuit of a storage battery pack. Background technique [0002] When the battery or the connection of the battery or the internal reasons of the battery cause the battery to be disconnected for more than the set time, it is said that there is an open circuit. The reasons for the open circuit of the battery are: [0003] (1) Contact problem: Because the screws of the connecting wire were not tightened during installation, the resistance of the connecting wire increases, and the battery will burn out the connecting wire after a long time, resulting in an open circuit. [0004] (2) Environmental problems: The environment in which the battery is located causes the battery connecting strip to be corroded, which will cause an open circuit over time. [0005] (3) Aging problem: The battery wiring has not been checked and maintained for a long t...
