Abstract

The embodiment of the invention discloses a battery working temperature control device and method for an electric vehicle, belonging to the technical field of electric vehicles. The control device includes: an information acquisition module, a temperature sensor, a control module and an antifreeze wall. The information acquisition module is used to acquire battery charge and discharge status information and battery information at different working temperatures of the battery in each use stage; the temperature sensor uses It is used to detect the ambient temperature of the battery currently in use; the control module is used to obtain a training model of suitable working temperature, obtain the suitable working temperature of the battery currently used according to the training model and the information of the currently used battery, and compare the ambient temperature with the suitable working temperature, When the comparison result is that the two temperatures are not equal, the antifreeze wall is controlled to adjust the ambient temperature to the suitable working temperature of the currently used battery. The invention can automatically adjust the working temperature of the battery, keep the best charge and discharge characteristics of the battery, and improve the reliability and 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 an electric vehicle. Background technique [0002] Electric vehicles are the future of the auto industry and have developed rapidly under the joint promotion of the government and auto manufacturers. The power battery used in electric vehicles has the most suitable working temperature during the charging and discharging process. It is not suitable for working under the conditions of harsh ambient temperature. When the battery works under the conditions of suitable temperature, it has the best charging and discharging characteristics, which will improve Battery reliability and working life. Under the low temperature or high temperature working environment, the charge and discharge characteristics of the power battery are very poor. For example, the battery activity will be poor, the effective capacitance of t...
