POWER BATTERY PACK

摘要

A power battery pack, comprising a plurality of individual storage batteries. A ridge is disposed on an outer surface of a terminal of each storage battery. Adjacent terminals of adjacent individual storage batteries are connected through the ridges on the respective outer surfaces thereof. The ridges are connected to form a three-dimensional grid structure. The three-dimensional grid structure is a heat conduction bridge of the individual storage batteries, and is capable of enhancing heat exchange. All or part of holes and gaps in the three-dimensional grid communicate with one another to form criss-crossed net shaped flow passages. A heat exchange medium passes the outer surface of the terminal through the net shaped flow passages, thereby implementing effective heat exchange of the power battery pack. Points and lines of the three-dimensional grid structure that cross and overlap one another form electrical connection points and electrical connection bands between adjacent individual storage batteries. Pretension enables the sharp tops of the ridges to deform and engage one another, so that the electrical connection points and the electrical connection bands form reliable contact. In the power battery pack of the present invention, heat flow lines and current lines do not converge, enhancing electrical connection, solving the heat exchange problem, and reducing the thermal resistance and electric resistance, thereby achieving a dual advantage.
