Battery temperature control device

Abstract

The invention discloses a battery temperature control device. A cooling device and a heating device are attached to two opposite sides of a battery module respectively, a temperature detection devicedetects the temperature of the battery module, and when the collected temperature meets the cooling condition, a controller controls a channel control switch to be switched to a first communicating state and controls a liquid in an external liquid storage device to be cooled and flow into the cooling device through the channel control switch so as to reduce the temperature of the battery module. When the collected temperature meets the heating condition, the controller controls the channel control switch to be switched to a second communicating state and controls the liquid in the external liquid storage device to be heated and flow into the heating device through the channel control switch so as to increase the temperature of the battery module. By means of the battery control device, thetemperature of the battery module can be decreased and can be increased, the working performance of the battery module is ensured and the influence on the service life is avoided.

Description

technical field [0001] The invention relates to the technical field of battery temperature monitoring, in particular to a battery temperature control device. Background technique [0002] Environmental pollution has had a great impact on people's health. Among them, exhaust gas pollution, as a typical representative of environmental pollution, has been highly valued, and electric vehicles, as a representative of the new energy industry, do not need to consume gasoline and have no exhaust gas pollution, which can reduce a large amount of exhaust gas. Pollution has developed rapidly in recent years. [0003] The key to an electric vehicle is the battery, which is used to drive the electric vehicle, that is, the battery is the power source of the electric vehicle. When the electric vehicle is running, the use of the battery will generate heat, which will increase the internal temperature of the battery. If the heat is not dissipated in time, the battery will work at a higher t...

AI Technical Summary

Problems solved by technology

When the electric vehicle is running, the use of the battery will generate heat, which will increase the internal temperature of the battery. If the heat is not dissipated in time, the battery will work at a higher temperature, which will reduce the output power, affect the battery life, and even cause self-heating, etc. Safety accident, if the battery temperature is too low and the resistance inside the battery is too high, the performance of the battery will be greatly reduced
