Abstract

The invention discloses a circuit and method for realizing full-cycle charging and discharging of different battery packs. The circuit includes a plurality of parallel battery modules; the battery module includes a battery, a charging MOS tube, a discharging MOS tube, and a current detection module. And the control module, the charging MOS tube, the discharging MOS tube, the current detection module and the battery are connected in series; the voltage sampling input terminal of the control module is connected with the battery, and the current sampling input terminal of the control module is connected with the current detection module , the first MOS tube control output end of the control module is connected to the charge MOS tube, and the second MOS tube control output end of the control module is connected to the discharge MOS tube. The present invention solves the problem of mutual charging and discharging caused by parallel connection of multiple battery modules with different voltage levels by controlling the opening and closing of the charging MOS tube and the discharging MOS tube; and realizes that all battery modules are in a parallel busbar In the circuit, each battery module realizes the full cycle process of charging and discharging.

Description

technical field [0001] The invention relates to a circuit and a method for realizing full-cycle charging and discharging of different battery packs. Background technique [0002] With the vigorous development of electronic technology, the use of medium and large battery packs is increasing. During the production, testing and use of these battery packs, many charging and discharging processes are used. [0003] The existing charging equipment or discharging equipment has the following disadvantages: [0004] 1. The battery packs need to use the same type of battery modules for parallel use, that is, the parallel battery packs require the same voltage for each battery, and it is not possible to parallel input and output battery modules of completely different types and voltage levels. Because in the battery pack, the difference between the monomers always exists. Take the capacity as an example, the difference will never disappear, but will gradually deteriorate. The same c...
