The invention provides a battery heat management system based on a separated heat pipe, a battery heat management method and a vehicle, the battery heat management system comprises a battery heat exchange system, the battery heat exchange system comprises the separated heat pipe, and the battery heat exchange system is communicated with a PTC heating system and an air conditioning system through the separated heat pipe and performs heat exchange with the PTC heating system and the air conditioning system; the air conditioning system and the battery heat exchange system each comprise an electromagnetic valve, and the closed state combination of the electromagnetic valves is used for controlling a heat management mode. The heat management mode comprises a battery passenger compartment refrigeration mode, a battery heating mode and a battery passenger compartment heating mode, and in the battery passenger compartment refrigeration mode, a water pump in the PTC heating system does not work. According to the application, the control of the battery passenger compartment refrigeration mode, the battery heating mode and the battery passenger compartment heating mode can be realized based on the combination of the closed states of the electromagnetic valves, so that the thermal management requirements in different scenes are met. And on the other hand, the energy consumption in the heat management process can be reduced through the separated heat pipe and reduction of the working time of the water pump in the PTC heating system.
本申请提供一种基于分离式热管的电池热管理系统、电池热管理方法和车辆,其中,电池热管理系统包括电池换热系统包括分离式热管,并通过分离式热管与PTC加热系统和空调系统连通并进行热交换;空调系统和电池换热系统均包括电磁阀,其中,电磁阀的闭合状态组合用于控制热管理模式;热管理模式包括电池乘员舱制冷模式、电池加热模式和电池乘员舱加热模式,其中,在电池乘员舱制冷模式中,PTC加热系统中的水泵不工作。本申请能够基于电磁阀的闭合状态组合实现电池乘员舱制冷模式、电池加热模式和电池乘员舱加热模式的控制,以满足不同场景下的热管理需求。另一方面,本申请通过分离式热管和降低PTC加热系统中的水泵的工作时长,可降低热管理过程的能耗。
