The invention discloses an electric vehicle thermal management method, device and equipment and a storage medium. The method comprises the steps that the temperature of a current power battery and a passenger compartment request signal in an electric vehicle are obtained; determining a power battery request signal input by a thermal management controller according to the temperature of the power battery; according to the power battery request signal and the passenger compartment request signal, the current use working condition of the electric vehicle thermal management system is determined; and performing thermal management on the power battery and the passenger compartment by adopting a thermal management controller according to the current use condition, the power battery request signal and the passenger compartment request signal. According to the invention, the thermal shock caused by heating of the power battery is reduced, the service life of the power battery is prolonged, and the control precision of thermal management of the whole electric vehicle thermal management system on the power battery and a passenger compartment is improved.

本发明公开了一种电动汽车整车热管理方法、装置、设备及存储介质，所述方法包括：获取电动汽车中当前动力电池的温度和乘员舱请求信号；根据动力电池的温度，确定热管理控制器输入的动力电池请求信号；根据动力电池请求信号和乘员舱请求信号，确定电动汽车整车热管理系统的当前使用工况；根据当前使用工况、动力电池请求信号和乘员舱请求信号，采用热管理控制器对动力电池和乘员舱进行热管理。本发明减少了动力电池加热的热冲击，提高了动力电池的使用寿命，提高了电动汽车整车热管理系统对动力电池和乘员舱进行热管理的控制精度。
