Problems solved by technology
In the prior art, there are usually two ways to maintain the proper working environment temperature range of the energy storage battery module: one way is to maintain the proper ambient temperature by consuming the energy of the energy storage battery module itself, obviously this way will lead to The reduction of power usage efficiency in the energy battery module; another way is to maintain an appropriate ambient temperature by adding a thermal insulation battery pack with excellent performance, so as to ensure the appropriate working temperature of the energy storage battery, so that more energy can be converted into kinetic energy of the car
The thermal insulation battery pack in the prior art usually has heat exchange with the energy storage battery module, the thermal insulation effect is not good, and the cost is high

Abstract
The invention discloses a heat preservation battery pack and an electric vehicle. The heat preservation battery pack comprises a battery module, a shell, a cooling system and a heat insulation assembly, wherein the battery module is arranged in the shell; the cooling system is arranged on the battery module; the cooling system is used for reducing the temperature of the battery module; the heat insulation assembly is arranged between the battery module and the shell; and the heat insulation assembly is used for reducing heat transfer between the battery module and the shell. According to the invention, the cooling system is arranged on the battery module to reduce the temperature of the battery module; the heat insulation assembly is arranged between the battery module and the shell, so that heat transfer between the battery module and the shell is reduced; therefore, efficient utilization of the cooling system is realized, the battery module has relatively stable working temperature,the energy utilization rate of the battery module is improved, and the service life of the battery module is prolonged.
Description
technical field [0001] The invention relates to the technical field of electric vehicle parts, in particular to a thermal insulation battery pack and an electric vehicle. Background technique [0002] With the improvement of society's awareness of environmental protection, green and energy-saving new energy vehicles are more and more favored by the market. One of the power sources of the existing mainstream new energy vehicles is the energy storage battery module. For the energy storage battery module, an appropriate ambient temperature can not only improve the energy utilization rate of the energy storage battery module itself, but also effectively improve the power consumption of the energy storage battery module. The service life and safety of the core; therefore, researchers try to maintain the working environment temperature of the energy storage battery module in a relatively stable and constant range. In the prior art, there are usually two ways to maintain the prope...
