Battery temperature control method, battery temperature control system, battery management system and vehicle

The embodiment of the invention provides a battery temperature control method, a battery temperature control system, a battery management system and a vehicle, and belongs to the field of battery temperature control. The battery temperature control method comprises the following steps: according to an initial temperature for charging a battery and a preset starting temperature of a temperature control system, determining a first time required for the battery to reach a current-limiting temperature from the initial temperature, the initial temperature being a battery temperature when the battery begins to be charged, and the preset starting temperature being a battery temperature when the battery begins to be charged; the preset starting temperature is larger than the initial temperature and smaller than the current limiting temperature; and determining the starting temperature and the starting time of the temperature control system according to the first time and the current-limiting charging time of the batt
