Abstract

The invention belongs to the circuit field, and provides a cell charging circuit and device. According to the cell charging circuit and device, a positive cell group can be charged through a positive cell group charging module during the positive half period of an alternating current, and a negative cell group can be charged through a negative cell group charging module during the negative half period of the alternating current, so that the periodical change characteristics of current direction of the alternating current are effectively utilized; the cell can be charged within the positive and negative half periods, so that electric energy is effectively utilized, energy sources are saved; and the cell charging circuit is formed only by the positive cell group charging module and the negative cell group charging module, so that the structure is simple and the cost is saved.

Description

technical field [0001] The invention belongs to the field of circuits, in particular to a battery charging circuit and device. Background technique [0002] Energy saving and environmental protection are the mainstream of industrial development in the world today. Rechargeable batteries not only save energy but also effectively control environmental pollution. [0003] However, in the prior art, the rechargeable battery is charged under the condition of alternating current, and the direction of the alternating current changes periodically, that is to say, the charging circuit in the prior art is charged in the positive half cycle of the alternating current. The battery is charged, but the negative half cycle is not effectively used, which is not conducive to energy saving and environmental protection, and even if the circuit is changed to charge the battery in both the positive half cycle and the negative half cycle of the AC, the circuit structure will be very complicated, ...
