Problems solved by technology
The liquid-cooled battery pack has high requirements on sealing performance, and the structure is relatively complex, involving many connections, sealing and other components, high cost, and high failure rate
The traditional air-cooled battery pack has a large structure, complex structure, and high cost. When the battery pack starts to work, the air-cooled system starts immediately, which consumes a lot of energy.

The invention discloses a power battery pack system which comprises a battery pack shell, a plurality of single batteries arranged in the battery pack shell at intervals and a cooling system connectedwith the battery pack shell and used for cooling the single batteries, and the cooling system comprises a weak cooling system and a strong cooling system. The weak cooling system and the strong cooling system can work independently or simultaneously; the weak cooling system comprises a heat transfer cooling assembly, and the strong cooling system comprises an air cooling device. The power batterypack system is simple in structure, small in overall size of the battery pack, low in requirement for sealing performance, low in cost, low in failure rate and suitable for various operation environments.
Description
technical field [0001] The invention belongs to the technical field of power batteries, and more specifically relates to a power battery pack system. Background technique [0002] During the high-current charging and discharging process of the power battery pack, a large amount of heat will accumulate inside the battery. If the heat is not controlled in time, the temperature of the battery module will rise sharply. In particular, large-capacity battery modules have higher energy density and higher heat release, which can easily lead to thermal runaway, causing problems such as gas release, smoke, and liquid leakage in the battery, and may even cause battery combustion and explosion. [0003] Traditional power battery pack systems use liquid cooling or air cooling for heat dissipation. The liquid-cooled battery pack has high requirements on sealing performance, and the structure is relatively complex, involving many connections, sealing and other components, high cost, and h...
