Abstract
The present invention provides a battery module and a liquid-cooled battery system that uses it, a battery cell and a current collector sheet, on the premise that the materials like the electrode and separator and so on are completely the same, energy density of the battery pack is greatly increased; the cell and the current collector sheet are fully welded connections, the joints are fewer and it is not prone to produce desoldering, also ensuring the stability of the of the cell tab and high current carrying capacity, and when putting the parallel battery module in series, the use of wires are avoided, thus reduces the volume of the battery pack; the innovative design for the liquid-cooled battery pack system, improves the thermal balance between the cells, and the heat-dissipation in battery pack distributes more evenly, the insulation property of the battery package is highly improved, controlling the heat-dissipation capacity of the system by adjusting the flow rate of the circulating pump, not only the unnecessary energy consumption can be avoided, but also have a better impact resistance.
