Problems solved by technology

[0004] However, even if the battery has some loss, when the discharge capacity reaches 80% of the rated capacity, the voltage of the battery cell can meet the condition of greater than 1.8V, so the detection effect of the prior art is not good.

Abstract

The invention provides a method and device for analyzing nuclear capacity data of a battery, and relates to the technical field of battery. The method comprises the following steps: acquiring a characteristic parameter when the battery is discharged to a preset capacity; comparing the characteristic parameter with a preset condition; if the characteristic parameter does not satisfy the preset condition, determining that the battery is unqualified; if the characteristic parameter satisfies the preset condition, comparing the characteristic parameter with the history characteristic parameter toacquire the health condition of the battery. The method analyzes the parameters of the battery nuclear capacity discharge in multiple stages, thereby more accurately determining the deterioration of the battery.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a method and device for analyzing battery core capacity data. Background technique [0002] In the substation, the storage battery plays an important role in ensuring the stability of the power supply as a backup power supply. Once there is a problem with the battery, it may cause equipment outage, power supply system paralysis or even other greater losses. Therefore, it is necessary to periodically check the battery through the nuclear capacity discharge test, and regularly diagnose the health status of the battery. [0003] At present, the diagnosis method for the health state of the battery is mainly: discharge the battery, and record the characteristic parameters of the battery every certain time interval, such as the voltage of the battery cell. When the discharge capacity of the battery reaches 80% of the rated capacity of the battery, stop recording the characteristic ...
