Description

【Technical field】 [0001] The invention relates to the technical field of charging circuits, in particular to a battery charging control circuit. 【Background technique】 [0002] The production and use of batteries require a series of charging and discharging steps such as formation and capacity separation to form finished batteries. The formation of batteries refers to the initial charging of newly produced batteries. "Formation" means "transformation", using chemical and electrochemical reactions to convert the plates into positive and negative plates with electrochemical characteristics. This process is an important link that affects the life of the battery. Therefore, the requirements for the charging control circuit of the battery are very strict. Battery formation is usually divided into two stages: constant current charging and constant voltage charging, that is, first use small current trickle charging to make the battery terminal voltage reach the end-of-discharge vo...
