Power battery device with temperature control function

Abstract

The invention discloses a power battery device with a temperature control function, the power battery device comprises a power battery device main body, the power battery device main body comprises a shell, a thin film layer, a temperature sensor and a controller, in order to make a new energy pure electric vehicle convenient to use at low temperature in winter, the thin film layer is designed on the inner bottom surface of a power battery cavity, and the temperature sensor is arranged on the inner bottom surface of the power battery cavity; the power battery pack is installed in the power battery cavity, and the thin film layer is located at the bottom of the power battery pack, so that after the thin film layer is started through the controller, the thin film layer generates heat to preheat the power battery pack, the power battery pack quickly reaches the starting temperature, and then energy output can be well conducted. When the temperature is high in summer, the thin film layer and the controller are in a disconnected state, the thin film layer has good thermal conductivity, and heat generated by the power battery pack is rapidly driven by the thin film layer to start the cooling and heat dissipation effect; low-power constant-temperature automatic adjustment control of the power battery pack is realized, so that the power battery pack of the new energy pure electric vehicle keeps good performance output.

Description

technical field [0001] The present invention relates to the technical field of power battery temperature control, and more particularly, to a power battery device with a temperature control function. Background technique [0002] With the continuous development of modern society and the continuous improvement of economic level, the domestic electric vehicle industry is also developing rapidly due to the advantages of environmental protection and low carbon; the existing pure electric vehicles generally use lithium-ion batteries as power batteries, and their cruising range is at room temperature. The superior energy is excellent, but in the low temperature environment such as winter, it is easy to cause serious power attenuation and reduce the cruising range. The actual driving experience of an automobile (EV). When the power battery is being charged conventionally, the inside of the battery will heat up. In order to reduce safety risks, a general vehicle will install a heat...

[0002] With the continuous development of modern society and the continuous improvement of economic level, the domestic electric vehicle industry has also developed rapidly due to the advantages of environmental protection and low carbon; existing pure electric vehicles generally use lithium-ion batteries as power batteries, and their cruising range is at room temperature. The performance is excellent, but in low temperature environments such as winter, it is easy to cause serious power attenuation and reduce the cruising range. According to the analysis of power battery attenuation data in low temperature environments, the cruising range will be reduced by 30% to 50%, which will greatly affect pure electric vehicles in northern winter areas.
