The invention provides an automobile thermal management system and an automobile. The automobile thermal management system comprises a compressor, a condenser and a cooler. The battery assembly, the compressor, the condenser and the cooler are sequentially communicated to form a first heat exchange loop. The condenser is communicated with the battery assembly to form a second heat exchange loop; the condenser is used for carrying out heat exchange on the first heat exchange medium and the second heat exchange medium, so that the second heat exchange medium heats the battery assembly; the automobile heat management system further comprises a preheating control valve and a preheating branch, the preheating control valve is arranged on the second heat exchange loop, and the preheating branch is connected with the battery assembly. The battery assembly comprises a plurality of battery cells, when the temperature difference among the battery cells exceeds a temperature difference threshold value, the preheating control valve is controlled to cut off the battery assembly and the second heat exchange loop, the preheating branch is controlled to communicate the battery assembly and the preheating branch to form a battery preheating loop, and the battery cells are preheated through the battery preheating loop. The service life is prolonged, and the battery capacity and output power are improved.

    本申请提供一种汽车热管理系统及汽车。汽车热管理系统包括压缩机、冷凝器、冷却器、电池组件,压缩机、冷凝器与冷却器依次连通并形成第一换热回路;冷凝器与电池组件连通并形成第二换热回路;冷凝器用于对第一换热介质与第二换热介质进行热交换,使第二换热介质给电池组件加热;汽车热管理系统还包括预热控制阀和预热支路,预热控制阀设于第二换热回路,预热支路与电池组件连接;电池组件包括多个电芯,在多个电芯之间的温差超过温差阈值时,控制预热控制阀,使电池组件与第二换热回路切断,且控制预热支路,使电池组件与预热支路连通并形成电池预热回路,多个电芯通过该电池预热回路进行预热。延长使用寿命,提高电池容量和输出功率。
