Abstract

The invention discloses an aging detection method and device for an individual battery. The method comprises the following steps: establishing a connection with a to-be-detected battery after receiving a detection request of detecting the aging degree of the to-be-detected battery; obtaining preset charge / discharge parameters corresponding to the detection request; performing a charge / discharge test on the to-be-detected battery according to the preset charge / discharge parameters through a constant-current constant-voltage charge / discharge circuit; acquiring a voltage parameter and a current parameter during the charge / discharge test of the to-be-detected battery; determining battery aging data corresponding to the voltage parameter and the current parameter. With the aging detection method and device, a problem of low detection speed of the aging degree of the battery in the prior art is solved and an effect of quickly and accurately detecting the aging degree of the individual battery is achieved.

Description

technical field [0001] The invention relates to the field of battery detection, in particular to a battery cell aging detection method and device. Background technique [0002] Now, batteries are widely used in various fields. In actual use, the battery is usually packaged into groups of battery cells, that is, used in the form of a battery pack, and the battery cells of the same battery pack are generally of the same model, and the initial parameters of the same model battery are very close. During the use of the battery, the aging degree of each battery cell needs to be checked frequently. If there are cells whose aging degree deviates greatly from the average level of the battery pack, they need to be eliminated to avoid affecting the performance of the entire battery pack. [0003] At present, the method of detecting the aging degree of the battery is generally a large current full discharge method. This method needs to measure the actual capacity of the battery by full...
