Abstract

Provided in the invention is a battery charger comprising a power module, a detection circuit, a micro processing circuit, a constant-voltage constant-current circuit, and an MOS driver circuit. The power module is used for carrying out work of ac-dc conversion and the like on commercial power; the detection circuit is used for detecting a current charging state of a storage battery and sending a detection result to the micro processing circuit; the micro processing circuit is used for generating a stage control signal based on the detection result and sending a stage control signal to the constant-voltage constant-current circuit; the constant-voltage constant-current circuit is used for converting the stage control signal into a PWM control signal, thereby controlling the MOS driver circuit to charge the storage battery; and the MOS driver circuit is used for converting the PWM control signal into a driver signal, thereby driving charging of the storage battery. With the battery charger, different charging currents correspond to different charging stages, thereby guaranteeing prevention of over-charging and under-charging phenomena of the storage battery; and the storage battery can be repaired, thereby prolonging the service life of the storage battery.

Description

technical field [0001] The invention relates to the fields of electronic technology and battery charging technology, in particular to a battery charger. Background technique [0002] Studies have shown that the charging process of the battery has the greatest impact on the life of the battery. Overcharging will cause the active material of the positive plate of the battery to loosen, fall off and soften, and the positive plate grid will be corroded; especially when the battery is severely overcharged, thermal runaway may occur and cause Batteries fail quickly. However, if the charge is insufficient, it will cause the formation of coarse crystals on the battery plates that are not easy to restore, forming sulfation, which will seriously shorten the life of the battery. [0003] Therefore, the service life of the battery depends to a large extent on the correct charging process. Currently, the known battery chargers on the market include: (1) Constant current charger, which m...
