Abstract

The invention provides a battery self-adaptive control device for batteries connected in parallel. The battery self-adaptive control device comprises a charging loop, a discharging loop, a charging control circuit, a discharging control circuit, a main control panel, a system end which is used for connecting a load or an external power supply, and a battery end which is used for connecting a battery. The charging loop and the discharging loop are simultaneously connected between the system end and the battery end. The main control panel controls the on-off of the charging loop via the charging control circuit, and controls the on-off of the discharging loop via the discharging control circuit. The main control controls the on-off of the discharging loop via the discharging control circuit. Therefore, the charging or discharging process of the battery can be precisely controlled via the charging control circuit and the discharging control circuit. The overcharging or over-discharging of the battery can be avoided and the service life of the battery is prolonged. Besides, a terminal voltage or an output current value of the battery can be self-adaptively adjusted and the battery can be conveniently merged into an online battery pack.

Description

technical field [0001] The invention belongs to the technical field of circuit control, and in particular relates to a battery self-adaptive control device and method applied to parallel battery packs. Background technique [0002] In the process of charging the battery or discharging the battery to the load, the battery is often overcharged or overdischarged, thereby reducing the service life of the battery. In addition, when the battery is integrated into the online battery pack, the terminal voltage of the battery needs to be the same as the terminal voltage of the online battery pack. Therefore, in the current technology, it is usually used to reduce the voltage of the online battery pack before the battery can be incorporated into the battery pack. in-line battery pack. However, the operation process of reducing the voltage of the online battery pack is extremely cumbersome, and has the disadvantages of long time and waste of energy.
