Abstract

The invention provides a temperature adjustment device for a battery box. The temperature adjustment device is arranged on an outer wall surface of the battery box; the temperature adjustment device comprises a multilayered structure; the multilayered structure comprises a phase change layer; the phase change layer comprises a phase change material; the phase change material can be used for absorbing or releasing heat; the phase change material is used for generating phase change to adjust the temperature of the battery box. According to the temperature adjustment device for the battery box, the phase change material capable of absorbing or releasing the heat is arranged in the multilayered structure and the temperature adjustment of the battery box is realized, so that the problem that the heat insulation efficiency and cooling efficiency of the battery box are low and the effect is poor so that normal utilization of the battery box is influenced is solved, and the utilization safetyand product quality of the battery box are improved; the temperature adjustment device for the battery box is safe and reliable, has remarkable heat insulation and cooling effects and is suggested tobe popularized and applied in a large scale.

Description

Technical field [0001] The invention relates to the technical field of batteries, in particular to a temperature regulating device for a battery box. Background technique [0002] The electrification of fuel vehicles has become a trend. Power batteries are the core components of electric vehicles. Battery safety has always been the primary concern of the industry. The most important factor affecting battery safety is whether the battery's operating temperature is in the appropriate temperature range ( 15℃-45℃), the suitable temperature range is conducive to the safe use of the battery and prolongs the service life of the battery. [0003] At present, the battery box of pure electric vehicles generally adopts natural cooling and PTC heating film heating for thermal management of the battery system. Such cooling and heating modes cannot effectively improve the low cooling efficiency and poor insulation effect of the battery box, which affects pure electric Normal use of the car. Su...
