Problems solved by technology
[0003] In order to solve the problems that the air source of the existing electric vehicle power pack has unequal effects on different internal battery modules, the heat dissipation effect of some battery modules is poor, and it is easy to cause uneven heat dissipation in the battery pack and affect the performance of the battery, a wind is proposed. The power supply for different internal battery modules is relatively equal, all battery modules can dissipate heat better, and the electric vehicle power pack guarantees battery performance

The invention discloses an electric vehicle power supply Pack, and relates to the field of a power supply. The electric vehicle power supply Pack comprises a power supply base and a power supply cover; a plurality of battery modules are in array distribution on the power supply base; a plurality of air channels are formed in the power supply base; the air channels are formed in the front and back direction of the power supply base; holes are formed in the front ends of the air channels and the back ends are sealed, and a plurality of air-outlet strip-shaped holes are formed in the two side walls; the air channels are formed between adjacent two columns of battery modules or between an edge side battery module and the power supply base edge; and air inlets are formed in the positions, corresponding to the holes in the front ends of the air channels, of the power supply cover. For solving the problems of relatively unequal effects on different battery modules in the interior by an air source of the existing electric vehicle power supply Pack, poor heat dissipation results of a part of the battery modules, easily caused uneven heat dissipation in the battery packs, and influence to the battery performance, the electric vehicle power supply Pack which can achieve relatively equal effects on different battery modules in the interior by the air source, realize relatively high heat dissipation to all the battery modules and ensure the battery performance is provided.
Description
technical field [0001] The invention relates to the field of power supplies, in particular to a power pack for electric vehicles. Background technique [0002] As people's awareness of environmental protection gradually strengthens, electric vehicles are gradually becoming popular, and power modules and power systems for electric vehicles and other fields are constantly being developed and improved. In view of the current continuous promotion and use of electric vehicles, considering the limitations of power supply systems in high or low temperature conditions and the reliability of battery cells, the heat dissipation and heating functions of power supplies have attracted more and more attention. Therefore, people try to solve the heat dissipation and heating problems of the power module by improving some battery pack equipment. For example, the patent authorization announcement number is CN202009061U, and the authorization announcement date is October 12, 2011. The power b...
