Automatic heat-preserving box for electric automobile battery in cold region

Abstract

An automatic battery heat-preserving box for an electric automobile battery in a cold region mainly comprises an automatic heat-preserving box base shell fixed to a chassis of an electric automobile, a rear box plate shell, a detachable left box plate shell, a right box plate shell, a front box plate shell and an a cover plate shell. When temperature of a temperature sensor is lower than a set value, after an electric heating wire controller of a rear box plate of the automatic battery heat-preserving box is started, a box plate electric heating wire generates heat, temperature rises, and when temperature of the heat-preserving box reaches a set value, work of the rear box plate electric heating wire of the heat-preserving box is interrupted. Due to the fact that the inner layer of the heat-preserving box shell is filled with efficient heat-preserving material aerogel, the automatic heat-preserving box for the electric automobile battery can preserve heat for a long time, the electric automobile battery is protected to normally work in a cold state, repeated heating of the rear box plate electric heating wire of the automatic heat-preserving box for the electric automobile battery is not needed, power consumption is greatly reduced, and the running distance of the automobile is increased. Due to the fact that part of box plates can be fast detached when it becomes hot, the automobile battery can still normally work.

Description

technical field [0001] The present invention relates to an electric vehicle battery automatic incubator, in particular to an electric vehicle battery automatic incubator in cold regions, which automatically controls the temperature inside the box by heating the electric heating wire of the electric vehicle battery automatic incubator, and applies high-efficiency The airgel insulation material keeps the temperature in the battery automatic insulation box within the set temperature range for a long time, ensures the normal operation of the battery, and saves electric energy. It belongs to the field of energy saving and environmental protection in the transportation industry. Background technique [0002] Too low ambient temperature will have a fatal impact on battery life and power. According to the information provided by the Boston Battery Company in the United States, if a battery with a capacity of 3500mAh works in an environment of -10°C, the power will rapidly decay to 5...

AI Technical Summary

Problems solved by technology

If the life of the battery is too short and needs to be replaced, it will greatly increase the cost of the car, thus losing the advantage of the low cost of using the electric car.

In addition, low temperature also poses challenges to the motor system

At low temperatures the battery will render the motor unable to start

It can be said that low temperature is a great enemy of electric vehicles. If the above problems are not solved, it will be difficult for electric vehicles to be popularized in the cold regions of the north.
