The invention discloses a heat pump heat management system of a heavy truck and the heavy truck, the heat pump heat management system comprises a battery circulation loop, a first refrigerant circulation loop, a second refrigerant circulation loop and a heating circulation loop, and the first refrigerant circulation loop and the second refrigerant circulation loop are arranged; whether the second refrigerant circulation loop participates in cooling of the battery pack or not can be determined by controlling the states of the three-way valve, the first five-way valve, the second five-way valve, the compressors and the water pumps, and the first refrigerant circulation system or the second refrigerant circulation system can be selectively adopted to conduct conventional air-conditioning cooling on the battery pack. In addition, the first refrigerant circulating system and the second refrigerant circulating system can be adopted to operate at the same time to cool the battery pack with higher strength, so that the cooling strength of the battery pack is increased to meet the maximum cooling requirement, and the phenomenon that the endurance is reduced due to the fact that the cooling requirement cannot be met due to the too large capacity of the battery pack of the heavy truck is avoided.

    本发明公开了一种重型卡车的热泵热管理系统和重型卡车,热泵热管理系统包括包括电池循环回路、第一制冷剂循环回路、第二制冷剂循环回路以及采暖循环回路,设置第一制冷剂循环回路和第二制冷剂循环回路,通过控制三通阀、第一五通阀、第二五通阀以及各个压缩机和水泵的状态,可以决定第二制冷剂循环回路是否参与对电池包的冷却,其可以选择性地采用第一制冷剂循环系统或者第二制冷剂循环系统来对电池包进行常规的空调冷却,也可以采用第一制冷剂循环系统和第二制冷剂循环系统同时运行来对电池包进行更大强度的冷却,从而加大电池包的冷却力度以满足最大冷却需求,避免重卡车辆的电池包容量过大而导致冷却需求无法满足而导致续航下降的现象。
