Embodiment Construction
[0018] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0019] Such as figure 1 , figure 2 As shown, the water-cooled battery module consists of an upper case 1, a lower case 2, an upper cover plate 3, a lower cover plate 4, an upper plate 5, a lower plate 6, a sleeve 7, a battery cell 8, and a water inlet pipe 9 And water outlet pipe 10 etc. constitute. Wherein, both the upper shell 1 and the lower shell 2 are preferably made of magnesium-aluminum alloy, and the upper shell 1 and the lower shell 2 are in contact with each other, and the two are fixed by brazing. Of course, as an equivalent replacement, the upper and lower shells can also be made of other metal materials or composite materials with high strength and low mass density, and the upper and lower shells can also be fixed by glue. The above-mentioned upper casing 1 and lower casing 2 form a box body with a cavity, and an upper cover plate 3 is arrang...

The invention discloses an electric car water-cooling battery module. An upper cover plate (3) is arranged on the top face of an upper shell (1). The top face of the upper cover plate (3) is provided with an upper pole plate (5). The bottom face of a lower shell (2) is provided with a lower cover plate (4). The bottom face of the lower cover plate (4) is provided with a lower pole plate (6). Pipe sleeves (7) are arranged in a cavity of a box formed by the upper shell (1) and the lower shell (2). A battery cell (8) is installed in each pipe sleeve (7). A water inlet pipe (9) is arranged on one side of the box. A water outlet pipe (10) is arranged on the other side of the box. According to the electric car water-cooling battery module, the temperature of the battery cells is decreased through heat transmission between the pipe sleeves and cooling liquid, the working environment of the whole battery box is kept consistent, the battery cell discharging depth is large, the consistency is good, the service life of the battery box is long, the using safety is good, and the electric car water-cooling battery module has the advantages of being ingenious in design, simple in structure, easy to arrange, remarkable in cooling effect and the like, and is applicable to different vehicle models.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a water-cooled battery module and a water-cooled battery box on the electric vehicle. Background technique [0002] Automobiles are one of the masterpieces of industrial civilization. For more than 100 years, the evolution of automobiles has improved people's living standards. However, the ensuing environmental and resource issues have brought crises to human society, and the development of new energy vehicles is imperative. As a key technology in new energy vehicles, battery packs and battery management systems have always restricted the development of new energy vehicles. [0003] At present, the common battery solutions for new energy electric vehicles on the market mostly adopt natural cooling or forced air cooling. Due to the characteristics of the battery itself and the harsh operating environment of the vehicle, the current battery has disadvantage...
