Cylindrical battery module with heating function

Abstract

The utility model discloses a cylindrical battery module with a heating function, which is characterized in that anodes and cathodes of cylindrical batteries are led out from the tops of the cylindrical batteries, the anodes and / or cathodes of a plurality of cylindrical batteries are connected through a current-carrying sheet, a lower bracket is provided with an accommodating groove, a plurality of isolation columns are arranged in the accommodating groove, and the accommodating groove is divided into a plurality of battery mounting stations by the isolation columns; the heating piece is arranged in the containing groove and provided with a plurality of positioning holes allowing the isolation columns to penetrate through, and the bottom of the cylindrical battery is installed on the battery installation station and makes heat conduction contact with the heating piece. The utility model has the beneficial effects that by arranging the accommodating groove and the isolating column in the lower bracket, the position fixation and mutual isolation of the cylindrical batteries can be realized, and the heating sheet can be directly laid in the accommodating groove to be in direct heat conduction contact with the bottoms of the cylindrical batteries, so that the structure is simplified, the installation and the maintenance are convenient, and the device is suitable for batch production; and heat can be effectively transferred to the cylindrical battery, and the heating effect is good.
