The invention discloses a thermal management system and an electric vehicle with the thermal management system. The thermal management system comprises a refrigerant branch and a heat dissipation branch which are communicated with a liquid cooling condenser, a compressor is arranged on the refrigerant branch, and the heat dissipation branch comprises a heat dissipation main branch, a charging heatdissipation branch and a power assembly heat dissipation branch; a three-way valve is arranged on the heat dissipation main branch; the three-way valve has a charging heat dissipation state enablingthe heat dissipation main branch to be communicated with the charging heat dissipation branch and a power assembly heat dissipation state enabling the heat dissipation main branch to be communicated with the power assembly heat dissipation branch, a radiator is arranged on the heat dissipation main branch, and the radiator is selectively connected with a charging wire harness or a power assembly heat dissipation accessory in series. According to the thermal management system, the charging heat dissipation branch used for cooling the charging wire harness can be expanded on the existing maturepower assembly heat dissipation branch, a heat dissipation system of the charging wire harness does not need to be independently arranged, and therefore the thermal management system is simple in structure.
本发明公开了一种热管理系统及具有该热管理系统的电动汽车。该热管理系统包括:与液冷冷凝器连通的制冷剂支路和散热支路,制冷剂支路上设置有压缩机,散热支路包括:散热主支路、充电散热支路及动力总成散热支路;散热主支路上设置有三通阀,三通阀具有使散热主支路与充电散热支路连通的充电散热状态以及使散热主支路与动力总成散热支路连通的动力总成散热状态,散热主支路上设置有散热器,散热器可选择地与充电线束或动力总成散热附件串联。根据本发明的热管理系统,可在现有成熟的动力总成散热支路上扩展用于对充电线束进行冷却的充电散热支路,而不必单独设置充电线束的散热系统,由此使得本发明的热管理系统结构简单。
