Seat assembly with battery cooling system and method for cooling battery

Abstract

The invention discloses a seat component with a battery cooling system. The seat component comprises a seat body, an airbag with a self-inflating function is arranged on the seat body, at least one first air tap used for sucking air and at least one second air tap used for deflation are arranged on the airbag, a first one-way valve used for being turned on when the airbag is inflated is arranged at the position of each first air tap, a second one-way valve used for being turned on when the airbag is deflated is arranged at the position of each second air tap, the second air taps are connected to one end of an air guide tube, and the other end of the air guide tube extends to a battery pack. Since the airbag capable of realizing self-inflating is arranged on the seat body, the airbag can be utilized to perform air cooling on the battery pack, a power source of a cooling mode is from gravitational potential energy of a human body, energy of the battery pack is not dissipated in the process of cooling, cooling of the battery pack and driving range of a vehicle are guaranteed at the same time, reliability of the battery pack is improved, and service life of the battery pack is prolonged.

Description

technical field [0001] The invention relates to the technical field of battery cooling, in particular to a seat assembly with a battery cooling system and a method for cooling the battery. Background technique [0002] The existing electric vehicle battery module cooling is divided into three types: liquid cooling, air cooling, and natural heat dissipation. The source power of the first two methods comes from the battery system, which is then used for battery heat dissipation. These two methods have good cooling effects, but both require additional cooling equipment, which increases manufacturing costs, and more importantly, increases overall energy consumption and reduces The cruising range of electric vehicles. For example, Chinese patent CN101700738B discloses an "electric vehicle cooling system", which includes a motor cooling circuit and a battery pack cooling circuit, and the motor cooling circuit and battery pack cooling circuit include a common set of cooling device...

AI Technical Summary

Problems solved by technology

Although this cooling system can better dissipate heat from the battery pack, it consumes energy itself, and the installed cooling system will also increase the manufacturing cost of the entire electric vehicle

[0003] However, the natural heat dissipation method has higher requirements on battery performance and overall structure. The cost of battery cooling through this method is higher than that of liquid cooling and air cooling. At the same time, it is also affected by operating conditions. Increased the instability of the method
