Battery equalizing charge device

The utility model relates to the technical field of charging and discloses a battery equalizing charge device. The device comprises a control module, wherein the control module monitors the voltage signal of each battery monomer; and when the voltage signal of the battery monomer exceeding the comparison voltage value is monitored, the control module controls a shunting unit connected in parallel with the battery monomer to shunt, and reduces the charging current of the battery monomer. In the battery equalizing charge device provided by the utility model, because the shunting unit is adopted, the voltage balance between monomer batteries can be automatically realized, thereby gradually reducing the inconsistency of a battery pack, ensuring the consistency of all the battery monomers in the battery pack after several times of circulating charging, and effectively guaranteeing the safety of each single lithium battery during use and prolonging the service life; and the device has the advantages of simple control, low cost, higher efficiency, and low heat rate, and can replace the special balancing chip with expensive price, thereby being widely applied in civil products supplied by lithium batteries.
