The embodiment of the invention provides an electric vehicle thermal management system and an electric vehicle, and the electric vehicle thermal management system comprises a plurality of passages including a motor passage, a battery passage and a refrigerant passage; the motor serves as a heating device of a motor path, and the battery serves as a heating device of a battery path; the main valve is a multi-way valve and comprises a plurality of outlets, one or more of the outlets are communicated with the multiple channels outside the main valve, the outlets are communicated pairwise in the main valve, the main valve comprises a plurality of communication modes, and the outlets communicated pairwise are different in different communication modes, so that the refrigerant channel and the multiple channels form different loops. The invention further provides the electric vehicle which comprises at least one set of motor, a passenger compartment, a battery and the electric vehicle thermal management system. According to the thermal management system of the electric vehicle, the multi-way water valve switching communication mode is adopted, so that heat is transferred according to actual requirements, energy is saved, meanwhile, the arrangement space is simple, and the cost is lower.

    本申请实施例提供一种电动汽车热管理系统及电动汽车,电动汽车热管理系统包括:多条通路,包括电机通路,电池通路以及冷媒通路;电机作为电机通路的升温装置、电池作为电池通路的升温装置;主阀,主阀为多通阀,包括多个出口,多个出口中的一个或多个在主阀外部与多条通路连通,多个出口在主阀内部两两连通,主阀包括多个连通方式,在不同连通方式下,两两连通的出口不同,使得冷媒通路与多个通路构成不同回路。本申请还提供一种电动汽车,包括至少一套电机、乘员舱、电池以及如上述电动汽车热管理系统。本申请的电动汽车热管理系统采用一个多通水阀切换连通方式实现热量根据实际需求进行转移,保证节能的同时又使布置空间简单,成本更低。
