Abstract

The invention relates to a power battery pack of an automobile start-stop system, comprising a box body and a battery pack arranged in the box body. The box body is provided with a plug connector. A box cover in screw fit with the box body is arranged on the upper end of the box body. The battery pack includes an electrical core component, a tray and a relay. The box body is provided with a fixingdevice inside. The electrical core component and the relay are connected with the fixing device by screws. The tray is fixed at the upper end of the electrical core component. The box cover is provided with gaps matching the positive and negative poles of the battery pack. The electrical core component is provided with insulating end plates at the two ends thereof, and the electrical core component is provided with heat conducting silica gel pads on the other two sides and at the bottom thereof. The types of materials are reduced, and cost is saved. The power battery pack has the advantages of more simple and compact structure design, reasonable layout and high integration. Natural heat dissipation is adopted, which can improve the reliability of the battery pack and is conducive to the cost reduction and efficiency increase of the battery pack.

Description

technical field [0001] The invention relates to a battery pack, in particular to a power battery pack for an automobile start-stop system. Background technique [0002] With the depletion of petroleum energy, harsh weather environment, increasing smog weather, the demand for environmentally friendly new energy vehicles continues to increase. By 2020, the average fuel consumption of passenger cars shall be ≤5L / 100km, and the fuel consumption of energy-saving passenger vehicles shall be ≤4.5L / 100km. In the prior art, the 48V start-stop system battery pack is composed of battery modules and other components, which is not only complex in structure, but also has many types of materials, which are scattered, costly, and large in size, which is not conducive to cost reduction and efficiency increase. Contents of the invention [0003] The purpose of the present invention is to provide a power battery pack for the start-stop system of an automobile. The battery pack not only redu...
