    摘要: The present disclosure provides a battery heat exchange system which comprises a liquid feeding mechanism, a heat exchange mechanism and a liquid draining mechanism. The liquid feeding mechanism provides a circulating liquid. The heat exchange mechanism is connected with the liquid feeding mechanism and comprises a plurality of heat exchange units and a plurality of connecting units; each heat exchange unit is used to heat or cool a corresponding battery module, and the plurality of connecting units are used to connect the heat exchange units together in series-parallel. The liquid draining mechanism is connected with the heat exchange mechanism, and the circulating liquid provided by the liquid feeding mechanism flows through the heat exchange mechanism and then is drained from the liquid draining mechanism.

    摘要: The application discloses a battery pack, vehicle and control method for alleviating thermal runaway spreading of a battery pack. The battery pack includes a plurality of secondary batteries and a spray pipeline. A housing of the secondary battery includes a weakened portion, so that a heat flow resulting from thermal runaway of the secondary battery is able to break through the weakened portion to be discharged. The spray pipeline is corresponding to weakened portions of the secondary batteries and is arranged at a spacing B from the weakened portions of the secondary batteries. At least a portion of the spray pipeline corresponding to the weakened portions is a breakthrough region which is able to form an opening under an action of the heat flow. The spray medium in the spray pipeline is sprayed to a secondary battery in thermal runaway via the opening.
