Abstract

The invention relates to a storage battery charging protection circuit used for charging a storage battery. The circuit comprises a charging circuit, a master control circuit and an execution control circuit which are respectively connected to the charging circuit and the master control circuit. The charging circuit is provided with a first input terminal, a second input terminal, a first output terminal and a second output terminal; the first input terminal is connected with a charging voltage Vin; the second input terminal is connected with a negative electrode of the storage battery; the first output terminal is connected to a system load; the second output terminal is connected to the execution control circuit; and the execution control circuit is connected to an anode of the storage battery. The storage battery charging protection circuit is simple in structure design and rich in function and integrates functions such as battery charge current limiting, battery undervoltage protection and automatic starting of charging after voltage recovery to achieve battery protection in a variety of ways to prevent voltage reverse feeding of the battery in the charging process and ensure that the usage life and safety of the storage battery.

Description

technical field [0001] The invention relates to the technical field of battery charging and discharging, in particular to a battery charging protection circuit. Background technique [0002] Nowadays, electronic products have become an indispensable tool for people's life and work, but as electronic products become more and more intelligent, the power consumption of electronic products is also getting faster and faster. Therefore, when people use electronic products frequently, they have to charge them repeatedly within a day. [0003] Most of the charging and discharging protection circuits of batteries in the prior art are integrated on the charger, but it is inappropriate and inconvenient to directly use the charger in some applications, such as limited installation space, cost constraints, or public considerations. power supply etc. At this time, a new solution is needed to complete the function Contents of the invention [0004] Based on this, the present invention...
