Battery Module

Abstract

A battery module includes a base device, a plurality of battery groups and a plurality of protecting circuit groups. The base device has a positive plate and a negative plate spaced from the positive plate. The battery groups are parallel-connected between the positive plate and the negative plate, each of which has a plurality of unit cells connected in series. Each of the protecting circuit groups is connected with the battery group and has a plurality of connecting terminals. The positive pole and the negative pole of each of the unit cells of the battery group are connected with the corresponding connecting terminals of the protecting circuit group. Therefore, the failed battery group or unit cell can be timely detected by the protecting circuit group so as to ensure the reliability and product life of the battery module.
