Automatic thermal insulation box used for electric vehicle battery in cold region

Abstract

The invention discloses an automatic thermal insulation box used for an electric vehicle battery in a cold region. The automatic thermal insulation box comprises a thermal insulation box body; a turning cover is movably mounted on the thermal insulation box body; the interior of the thermal insulation box body is divided into four battery positioning cabins by an isolation frame; temperature control elements are embedded in the isolation frame; and an electric heating film is arranged at the bottoms of the battery positioning cabins. The turning cover is movably connected with the thermal insulation box body, so that a sealed thermal insulation effect can be realized after combination while a relatively good heat dissipation and ventilation effect can be ensured after detachment; the thermal insulation box body adopts three-layer structural design, and an aerogel thermal insulation material has extremely high thermal insulation and thermal-shielding performance and is relatively light in weight, so that the power consumption of the electric heating film can be greatly lowered; and in addition, by virtue of aluminum foil, outwardly-dissipated radiation in battery operation can be lowered.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an automatic incubator for electric vehicle batteries in cold regions. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. [0003] Existing electric vehicles generally do not have insulation structures. In some areas with relatively cold climates, it is easy to affect the normal operation of the battery. Since the battery generates heat by itself after operation, the hot and cold environment will affect the service life of the battery. Therefore, we propose An automatic incubator for electric vehicle batteries in cold regions solves the above existing problems. C...
