The invention provides an electric vehicle battery temperature control method and device, a vehicle and a storage medium. The vehicle comprises an air conditioner indirect cooling liquid loop and a battery indirect cooling liquid loop which conduct heat exchange through an indirect heat exchanger. The method comprises the steps that when a vehicle is in a charging mode and an air conditioning system operates in a heating mode, the battery temperature and the vehicle exterior environment temperature are obtained; when the ambient temperature outside the vehicle is smaller than or equal to the ambient temperature threshold value and the battery temperature is larger than a first battery temperature threshold value, the running state of a battery indirect cooling liquid loop is adjusted to improve the heat exchange efficiency with an air conditioner indirect cooling liquid loop, and a battery passive cooling instruction is sent to an air conditioner system controller; the air conditioner system controller is indicated to adjust the state of the air conditioner indirect cooling liquid loop according to the battery passive cooling instruction. The heat of the battery can be fully utilized to heat the passenger compartment in a low-temperature environment, the energy conversion efficiency and the utilization rate are improved, and meanwhile the air conditioner heating efficiency is improved.
