Abstract

The invention relates to an average charging method for a rechargeable battery group in series. When charging, a switch module between the rechargeable batteries is under a turn-on condition; the batteries are under a tandem condition; all the control switches connected with the anodes of the rechargeable battery group and the control switches connected with the cathodes of the rechargeable battery group are under an open circuit condition; a charger charges the rechargeable battery group in series and stops charging after a period of time; the switch module between the rechargeable batteries is under the open circuit condition; all the control switches connected with the anodes of the rechargeable battery group and the control switches connected with the cathodes of the rechargeable battery group are under the turn-on condition; the rechargeable batteries with high voltage is caused to charge the rechargeable batteries with low voltage, which leads the voltage of the rechargeable batteries to be even; after repeating for a plurality of times, the charging is finished until standard voltage is detected to be achieved. The method has the advantages of reasonable structure, a pulse charging mode and being capable of fully prolonging the service life of the rechargeable battery group.

Description

technical field [0001] The invention relates to the charging field of rechargeable battery packs, in particular to a method and device for equalizing charging of rechargeable battery packs used in series. Background technique [0002] With the rapid development of science and technology, many portable electronic products are becoming smaller and smaller, with complete functions and low prices, and are favored by more and more people. With the increasing demand for portable electronic products such as personal digital assistants, digital cameras, and walkmans, the usage of batteries is also increasing, and the relative battery capacity is also required to be larger and the service life is longer. The longer the charging time is, the shorter the charging time is. The charger is required to charge multiple rechargeable batteries at the same time, and it must also be charged in a balanced manner. At present, in the prior art, charging the rechargeable battery pack generally use...
