Abstract

The invention discloses a temperature compensation system and method for lithium battery capacity measurement, and a storage medium. The temperature compensation system includes an offline training learning system, an online temperature compensation system and a sampling verification system. The method comprises the steps of: obtaining a characteristic curve of the capacity and the temperature ofa certain type of lithium ion battery through offline training; measuring and obtaining the real-time temperature and test capacity of the certain type of the lithium ion battery; using the real-timetemperature and the characteristic curve to compensate the test capacity to obtain the normal temperature compensation capacity of the certain type of the lithium ion battery; and performing samplingof certain type of the lithium ion battery. The storage medium stores computer programs executed by a processor to achieve the method provided by the invention. The temperature control requirements ofthe lithium ion battery for the factory area in the production process in the capacity grading process through temperature compensation can be reduced.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a temperature compensation system and method for lithium battery capacity measurement, and a storage medium. Background technique [0002] The capacity of a lithium-ion battery is a key performance indicator that represents the ability of a lithium-ion battery to store and release an amount of energy. In the production process of lithium-ion batteries, factors such as the ratio of positive and negative electrode materials, the thickness and uniformity of coating, the dry humidity of baking, the process of formation and the environment will all affect the capacity of lithium-ion batteries. Therefore, in the production process of lithium-ion batteries, there is a special capacity separation process to measure the capacity of each lithium-ion battery, and the measured capacity provides data for the subsequent sorting process and assembly process. The capacity separati...
