The invention provides an electric vehicle battery pack temperature pre-adjusting system. The electric vehicle battery pack temperature pre-adjusting system comprises a battery pack, a heating element, a refrigerating element, a battery pack temperature sensor, an environment temperature sensor, an environment anemometer, a positioning element and a networking element. A vehicle owner can reserve the next starting time of the vehicle, and the vehicle performs thermal management processing in advance according to the external environment condition to ensure that the traveling vehicle is started smoothly. The influence of environment temperature and wind speed factors on the heat exchange of the battery pack is considered at the same time, the weather forecast information is corrected in combination with specific measured data, and the heat exchange proportion values at different wind speeds are calibrated in advance, so that the considered factors are comprehensive, scientific and reasonable, the battery pack pre-adjustment logic is simple, the use is convenient, and the working efficiency is improved. And the temperature of the battery pack can be adjusted in place at the reserved starting moment, and the advantages of high efficiency and energy conservation are achieved.
本发明提供一种电动汽车电池包温度预先调节系统,包括电池包、加热元件、制冷元件、电池包温度传感器、环境温度传感器、环境风速计、定位元件和联网元件。车主可预约车辆下次启动时间,车辆根据外界环境情况提前进行热管理处理,保证出行车辆起动顺利。本发明同时考虑了环境气温和风速因素对电池包换热的影响,结合了具体实测数据对天气预报信息进行修正,并预先标定了不同风速下的换热比例值,故考虑因素全面、科学合理,电池包预先调节逻辑简单、使用方便,能恰到好处地在预约启动时刻将电池包温度调节到位,具有高效节能的优点。
