Abstract

The utility model discloses a nickel-metal hydride battery module which comprises a plurality of single batteries and a protective shell, positive and negative electrodes of the single batteries are sequentially welded and connected in series to form a battery pack, the protective shell is arranged outside the battery pack and comprises a first shell and a second shell which are connected through a buckle, and the first shell and the second shell are buckled to form an accommodating cavity of the battery pack. Bosses internally provided with blind holes are arranged at the two ends of the bottom of the first shell, the blind holes are in threaded connection with fixing bolts connected with a frame, inclined faces are arranged on the inner sides of the bosses on the two sides, unfilled corners are arranged at the positions, opposite to the bosses and the inclined faces, of the second shell, and the rest parts of the first shell and the rest parts of the second shell are of symmetrical structures. According to the utility model, the single batteries are fixed in the protective shell and are connected in series to form a group, and the bottom of the protective shell is provided with the heat dissipation holes and the blind holes screwed with the fixed bolts, so that the insulation and heat dissipation of the module are realized, the self power consumption of the module caused by the conduction of condensate water to the frame is avoided, and the module has the characteristics of good group consistency, simple assembly and sealing process, and good insulation and heat dissipation performance.
