Abstract

An embodiment of the invention discloses an electric vehicle battery working temperature control device and method, and belongs to the technical field of electric vehicles. The control device includesan information acquisition module, a temperature sensor, a control module and an antifreeze wall; the information acquisition module is used for acquiring battery charge and discharge state information and battery information of a battery at different operating temperatures in all using stages; the temperature sensor is used for detecting the ambient temperature of the currently-used battery; andthe control module is used for obtaining a suitable operating temperature training model, obtaining the suitable operating temperature of the currently-used battery according to the training model and the information of the currently-used battery, comparing the ambient temperature with the suitable operating temperature and controlling the antifreeze wall to adjust the ambient temperature to thesuitable operating temperature of the currently-used battery when a comparison result shows that the two temperatures are not equal. The battery working temperature control device and method can automatically adjust the working temperature of the battery, keep the battery to have best charge and discharge characteristics, improve the reliability of the battery and prolong the service life of the battery.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery operating temperature control device and method for electric vehicles. Background technique [0002] Electric vehicles are the future of the automobile industry, and they have developed rapidly under the joint promotion of the government and automobile manufacturers. The power battery used in electric vehicles has the most suitable working temperature during the charging and discharging process, which is not suitable for working under harsh ambient temperature conditions. When the battery works under suitable temperature conditions, it has the best charging and discharging characteristics, which will improve Battery reliability and working life. However, in a low-temperature or high-temperature working environment, the charging and discharging characteristics of the power battery are very poor. Damage, seriously affecting the reliability and service life of ...
