Description

Technical field:

[0001] The utility model relates to a battery pack with heat dissipation and shockproof functions, belonging to the technical field of battery packs. Background technology:

[0002] At present, the battery pack will generate a certain amount of heat when charging, but the existing battery pack charger is not equipped with a heat dissipation function, and cannot play a heat dissipation effect when the battery pack is charging; before the existing battery pack is connected to the chassis, it is generally fixed together with the battery pack bracket, and then the bracket is connected to the chassis. In order to increase the energy density, the strength of the battery pack box will be relatively weakened. The existing battery pack and the bracket that fixes the battery pack are not tightly connected due to processing, manufacturing, transportation and other reasons, which always leads to a gap between the battery pack and the bracket. Therefore, during the transportation of the vehicle, there will be a problem of up and down vibration of the battery pack module. Long-term vibration will cause the bus to break, resulting in the inability to charge and discharge, or before the break, the current capacity will be weakened, causing the battery pack temperature to rise, causing spontaneous combustion and other problems.
