Abstract

Provided herein is an efficient and energy-saving system for battery formation and grading, which includes a busbar (1), a charging module (2), a discharging module (3), a load transfer unit (5), a limiting unit (6) and a formation fixture (7). The busbar (1) is connected to an external constant current source to provide working power for the charging module (2) and the discharging module (3). The formation fixture (7) is used for loading a plurality of lithium batteries to be formation and grading. The load transfer unit (5) is used for moving a lithium battery (4) from a current station to a next station. The limiting unit (6) is used for intercepting and positioning the lithium battery (4) when it reaches a designated station, and releasing the lithium battery (4) when it is about to move to the next station. Advantageously, the charging module (2) and the discharging module (3) are arranged independently, so that all the charging module (2) and the discharging module (3) can work simultaneously without forming any idle charging circuit or discharging circuit, thereby reducing the energy loss and system cost due to idle circuits.
