Problems solved by technology

[0002] Since the battery pack is made up of several single batteries in series, the current flowing through each battery is the same when charging in a conventional way, but the balance problem is caused by the difference of each battery.
Studies have shown that this imbalance reduces the performance of the entire battery pack, which in turn shortens the life of the battery

Abstract

The invention relates to an equalization maintenance instrument, which comprises a voltage detection module, a system control module, a series charging module, a plurality of parallel charging modulesand a plurality of discharge equalization modules. The input end of the series charging module is electrically connected with the charging power supply. The output end of the series charging module is electrically connected with the battery pack. The parallel charging module comprises a charging sub-module and a switch array sub-module. The first input end of the charging sub-module is electrically connected with the charging power supply, the output end of the charging sub-module is electrically connected with the input end of the switch array sub-module, and the output end of the switch array sub-module is electrically connected with the single battery. The input end of the system control module is electrically connected with the charging power supply; the charging sub-module, the voltage detection module and the discharging equalization module are electrically connected to the output end of the control module. The voltage detection module is correspondingly and electrically connected with the single batteries. The input end of the discharge equalization module is electrically connected with the anode of the single battery, and the output end of the discharge equalization moduleis electrically connected with the cathode of the single battery. The battery equalization problem is solved, the battery performance is improved, and the battery life is prolonged.

Description

technical field [0001] The present disclosure relates to the field of battery maintenance, in particular to a balance maintenance instrument. Background technique [0002] Since the storage battery pack is made up of several single batteries connected in series, the current flowing through each storage battery is the same when charging in the conventional method, but the balance problem is caused due to the difference of each battery. Studies have shown that this imbalance reduces the performance of the entire battery pack, which in turn shortens the life of the battery. Contents of the invention [0003] In view of this, the present disclosure proposes a balance maintenance instrument, which completely solves the problem of battery balance, and truly plays a role in improving battery performance and prolonging battery life. [0004] According to one aspect of the present disclosure, there is provided a balance maintenance instrument for charging a battery pack, the batte...
