Abstract

The invention discloses a storage battery charging circuit having a charging protection function. The storage battery charging circuit comprises a bridge rectifier circuit formed by first-fourth rectifier diodes, and a charging IC circuit. The storage battery charging circuit also comprises first-third diodes, first-eighth capacitors, first-ninth resistors, a first triode and a second triode. The storage battery charging circuit is simple in structure design and convenient to use; and magnitude of charging current is effectively controlled, so that even if being charged for a long time, a storage battery does not heat, thereby preventing the events of explosion and flaming and the like due to pole plate shedding, breakage and short circuit.

Description

technical field [0001] The invention discloses a storage battery charging circuit with charging protection, and relates to the technical field of storage battery charging circuit design. Background technique [0002] After the battery is discharged, use direct current to pass through the battery in the opposite direction to the discharge current to restore its working ability. This process is called battery charging. When charging the battery, the positive pole of the battery is connected to the positive pole of the power supply, and the negative pole of the battery is connected to the negative pole of the power supply. The voltage of the charging power supply must be higher than the total electromotive force of the battery. There are two charging methods: constant current charging and constant voltage charging. [0003] There is a large amount of ionizable solution such as sulfuric acid in the battery. When the power is plugged in, the current passes through the lead plate...
