The integrated thermal management system of the electric vehicle comprises a battery thermal management system, an electric drive thermal management system and a cabin air conditioning system, and a first heat exchange channel with a battery heat exchanger is connected into a heat exchange circulation loop of the battery thermal management system; a cooling circulation loop of the electric drive heat management system supplies heat to a heat exchange circulation loop under the condition that battery heat supply conditions are met, a heat pump air conditioner main loop of the cabin air conditioner system is used for adjusting the temperature of a cabin and can be switched between a refrigeration mode and a heating mode, and a battery heat exchange branch is connected to the heat pump air conditioner main loop in a bypass mode. A second heat exchange channel with a battery heat exchanger is connected into the battery heat exchange branch, so that the battery heat exchange branch exchanges heat with the heat exchange circulation loop under the condition that a temperature adjustment demand instruction of the power battery is triggered, and the temperature adjustment of the power battery can fully utilize the heat generated by the electric drive heat management system and the temperature adjustment of the shared cabin air conditioning system; and the energy utilization rate of the whole thermal management system is improved.

    本发明公开了一种电动车集成热管理系统及电动车,电动车集成热管理系统包括电池热管理系统、电驱热管理系统和座舱空调系统,电池热管理系统的换热循环回路中连入有电池换热器的第一换热通道,电驱热管理系统的冷却循环回路在满足电池供热条件的情况下向换热循环回路供热,座舱空调系统的热泵空调主回路用于对座舱温度进行调节并可在制冷模式与制热模式之间进行切换,电池换热支路旁接于热泵空调主回路上,电池换热支路中连入有电池换热器的第二换热通道,以使得在触发动力电池的调温需求指令的情况下与换热循环回路进行换热,则动力电池的调温可以充分利用电驱热管理系统的产热以及共享座舱空调系统的调温,提升整个热管理系统的能量利用率。
