The invention provides a heating control method and device for a vehicle battery pack, a controller and a medium, the battery pack of the vehicle is heated based on an electric drive heating system of the vehicle, and the method comprises the steps that the initial operation power, the initial oil pump flow and the initial water pump flow of a motor of the electric drive heating system are determined; based on the initial operation power, the initial oil pump flow and the initial water pump flow, a motor, an oil pump and a water pump of the electrically-driven heating system are controlled to operate; the current temperature rising slope of a water outlet of a heat exchanger of the electric drive heating system is obtained; and dynamically adjusting at least one of the flow of the oil pump, the flow of the water pump and the operating power of the motor based on the current temperature rise slope until the battery pack reaches the target temperature. According to the invention, the problems of low system control precision, high heating energy consumption and the like when the electric drive heating system heats the battery pack are solved.

    本发明提供一种车辆电池包的加热控制方法、装置及控制器和介质,基于车辆的电驱加热系统为车辆的电池包进行加热,该方法包括:确定电驱加热系统的电机的初始运行功率、初始油泵流量和初始水泵流量;基于初始运行功率、初始油泵流量和初始水泵流量分别控制电驱加热系统的电机、油泵和水泵运行;获取电驱加热系统的换热器的出水口的当前温度上升斜率;基于当前温度上升斜率动态调节油泵的流量、水泵的流量和电机的运行功率中的至少一个,直至电池包达到目标温度。本发明解决了电驱加热系统对电池包进行加热时,系统控制精度低、加热能耗高等问题。
