Embodiment Construction

[0022] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0023] see figure 1 As shown, a thermal management system 1 for a vehicle (such as an electric vehicle) battery such as a power battery according to the present invention includes a battery box 10 installed in the battery installation area of ​​the vehicle, an air inlet duct 20 and an air outlet duct communicated with the battery box 30. From figure 1 It can be seen that the air intake duct 20 is configured to guide the air introduced from the air intake at the front side of the vehicle into the battery box 10 . A plurality of battery cells 100 to be heated or cooled by the inflow air flowing in from the air intake duct is disposed in the battery box 10 arranged in a row. The thermal management system 1 also includes an air treatment...

Abstract

The invention relates to a heat management system for a vehicle battery. The system comprises a battery box and an air inlet pipeline and an air outlet pipeline in fluid connection with the battery box; multiple battery cells to be heated or cooled by the inflowing air flowing from an air inlet pipeline are arranged in the battery box in layout; the heat management system is characterized in thatthe battery cells are arranged in a non-uniform way on a direction vertical to a flowing direction of the inflowing air in a placement plane of the monomer cell.

Description

technical field [0001] The present invention relates to the technical field of thermal management of batteries, and more particularly relates to a thermal management system for vehicle batteries such as power batteries. Background technique [0002] In recent years, countries all over the world are vigorously promoting and developing electric vehicles with low energy consumption and low emissions to solve the increasingly serious environmental pollution and energy crisis. Electric vehicles use a power battery pack as a power source. Therefore, the power battery pack is a key factor affecting the overall performance of electric vehicles. In order to meet the high power requirements of electric vehicles, battery cells are usually densely arranged to form a high power density battery pack. Such an arrangement will cause the battery to generate a large amount of chemical reaction heat and Joule heat during actual operation, which will lead to a rapid rise in the surface temper...
