摘要： A thermal management system includes a refrigerant loop, a motor coolant loop, and a battery coolant loop. The refrigerant loop includes a first refrigerant main-line, a second refrigerant main-line, a first refrigerant branch, and a second refrigerant branch. The first refrigerant main-line includes a compressor, the second refrigerant main-line includes a cabin condenser, the first refrigerant branch includes a cabin evaporator, the second refrigerant branch includes a radiator. The first refrigerant main-line and the second refrigerant main-line selectively communicate with one of the first and second refrigerant branches. The battery coolant loop includes a coolant main-line, a first coolant branch connected to the cabin evaporator, a second coolant branch connected to the cabin condenser, and a third coolant branch. The coolant main-line selectively communicates with at least one of the first to third coolant branches. The battery coolant loop connects to the motor coolant loop in series or in parallel.

摘要： A thermal management system includes a refrigerant loop, a battery coolant loop, and a motor coolant loop. The refrigerant loop includes a compressor selectively communicating with at least two of a condenser, an evaporator, and a heat exchanger. The battery coolant loop includes a first bypass path connected to the heat exchanger. The motor coolant loop includes a second bypass path connected to the radiator. A valve package includes ten outer ports and eight inner channels. Three outer ports connect to the heat exchanger, one of which is connected to the first bypass path. Two outer ports connect to the power supply system. Two outer ports connect to the powertrain system. Three outer ports connect to the radiator, one of which is connected to the second bypass path. Eight of the ten outer ports selectively communicate with four of the eight inner channels.
