Problems solved by technology

However, limited by technical conditions, it is difficult to make a major breakthrough in the performance of power batteries in the short term. If electric vehicles are to be commercialized, it is necessary to ensure that the battery works under optimal conditions to improve its performance and extend its life.
The power battery pack used in electric vehicles is composed of multiple battery modules connected in series and parallel. During the charging and discharging process of the battery, heat will be generated, which will increase the overall temperature of the battery pack, and when the temperature is too high, it will seriously affect the performance of the battery. life, or even directly lead to battery failure
At the same time, when charging and discharging, the heat release or uneven heat dissipation of each single cell in the battery pack will cause temperature differences in the battery pack, and batteries with high local temperatures will age faster, and long-term operation will destroy the consistency of the battery pack, thus causing battery pack failure

Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, an electric vehicle battery air classification cooling device includes a rectangular parallelepiped battery box 101 for installing battery modules 103, eight cylindrical battery modules 103 are arranged laterally in the battery box 101 along the cooling air flow direction, each The battery modules 103 are arranged in a staggered arrangement. The battery box side walls 102 on the left and right sides of the battery box 101 are symmetrically provided with four air classification guides 104 that extend outwards and guide air into the battery box 101 along the direction of air flow. The height of the guides 104 is It is the same height as the side of the battery case.

[0028] The air classification deflector 104 includes a first wind deflector 1041 and a second wind deflector 1042 connected to the side wall 102 of the battery box, and is sealed and connected with the first wind deflector 1041 and the second wind deflector 1042 T...

Embodiment 2

[0034] see Figure 4 ~ Figure 5 The difference between this embodiment and Embodiment 1 is that in this embodiment, the battery modules 103 are arranged in a row, the number of battery modules 103 is also eight, and the flow guiding device 104 is located in two rows of battery modules Between 103.

Embodiment 3

[0036] The difference between this embodiment and Embodiment 1 is that: the battery case 101 is cylindrical, and the battery modules 103 are longitudinally arranged in the battery case 101 along the cooling air flow direction.

[0037] The above-mentioned embodiments can also be used to deal with occasions other than electric vehicles that require cooling of battery packs.

Abstract

The invention discloses an air-staged cooling device for batteries of an electric vehicle. The air-staged cooling device comprises a battery box body used for installing battery modules, wherein a plurality of air-staged flow guide devices which extend outwards and are used for guiding air in the battery box body are symmetrically arranged on the battery box body sidewalls at the left side and the right side of the battery box body along the flowing direction of cooling air, and the material of the flow guide devices is the same as that of the battery box body. During operation of the air-staged cooling device disclosed by the invention, the main cooling air enters from the front end of the battery box and exits from the rear end; meanwhile, a part of the cooling air enters the battery box body through the air-staged flow guide devices arranged at different positions on the sidewalls of the battery box body, and thus guaranteeing that the temperatures of the various battery modules in the battery box body are uniformly distributed, and keep the optimal operation temperature range. The air-staged cooling device disclosed by the invention is simple in structure, economic and practical, effectively solves the problem of non-uniform distribution of the temperatures of the various battery modules in the air cooling battery box body, can meet the temperature control requirements of various batteries, and has a great commercial economic application prospect.

Description

technical field [0001] The invention relates to a cooling device, in particular to an electric vehicle battery air classification cooling device. Background technique [0002] Batteries are one of the core components of electric vehicles, and their performance directly affects the performance of electric vehicles. However, limited by technical conditions, it is difficult to make a major breakthrough in the performance of power batteries in the short term. If electric vehicles are to be commercialized, it is necessary to ensure that the battery works under optimal conditions to improve its performance and extend its life. . The power battery pack used in electric vehicles is composed of multiple battery modules connected in series and parallel. During the charging and discharging process of the battery, heat will be generated, which will increase the overall temperature of the battery pack, and when the temperature is too high, it will seriously affect the performance of the...
