Abstract
The invention provides a battery module for improving safety, which comprises at least one fixing frame, a plurality of battery cells, a plurality of conductive sheets and a plurality of protection units. The battery cells are arranged on the fixing frame. Each conductive sheet is connected with two battery cells in series, each of the protection units is respectively connected with two conductive sheets, and the battery cells connected with the conductive sheets are connected in parallel via the protection unit. When the temperature of the protection unit is greater than a preset temperature, the protection unit will be blown, thereby preventing the battery cells from charging the defective battery cell, resulting in the defective battery cell to melt or explode.
