Thermal management system and control method for same

A thermal management system, comprising:

• a primary system and a secondary system;
• the primary system comprising a primary refrigerant system and a primary coolant system;
• the primary system comprising a first heat exchanger;
• the first heat exchanger comprising a first heat exchange portion and a second heat exchange portion which are not communicated;
• the first heat exchange portion and the second heat exchange portion being configured to perform heat exchange;
• the primary refrigerant system comprising a first compressor, a second heat exchanger, a first throttler and the first heat exchange portion;
• the primary coolant system comprising the second heat exchange portion;
• the secondary system comprising a secondary refrigerant system and a secondary coolant system;
• the secondary system comprising a third heat exchanger;
• the third heat exchanger comprising a third heat exchange portion and a fourth heat exchange portion which are not communicated;
• the third heat exchange portion and the fourth heat exchange portion being configured to perform heat exchange;
• the secondary refrigerant system comprising a second compressor, a fourth heat exchanger, a second throttler and the third heat exchange portion;
• the secondary coolant system comprising the fourth heat exchange portion;
• the thermal management system comprising a battery heat exchange assembly;
• the thermal management system having a battery rapid heat dissipation mode;
• wherein in the battery rapid heat dissipation mode:
• an outlet of the first compressor communicates with a first port of the second heat exchanger;
• a second port of the second heat exchanger communicates with a first port of the first throttler;
• a second port of the first throttler communicates with a first port of the first heat exchange portion;
• a second port of the first heat exchange portion communicates with an inlet of the first compressor;
• the battery heat exchange assembly communicates with the second heat exchange portion;
• an outlet of the second compressor communicates with a first port of the fourth heat exchanger;
• a second port of the fourth heat exchanger communicates with a first port of the second throttler;
• a second port of the second throttler communicates with a first port of the third heat exchange portion;
• a second port of the third heat exchange portion communicates with an inlet of the second compressor;
• the battery heat exchange assembly communicates with the fourth heat exchange portion;
• wherein the secondary refrigerant system further comprises a second flow path switcher;
• the second flow path switcher comprises a fourth port, a fifth port, a sixth port and a seventh port;
• the fourth port communicates with the outlet of the second compressor;
• the fifth port communicates with the third heat exchange portion;
• the sixth port communicates with the inlet of the second compressor;
• the seventh port communicates with the fourth heat exchanger;
• the second flow path switcher comprises a first working state and a second working state;
• in the first working state, the fourth port communicates with the seventh port;
• the fifth port communicates with the sixth port;
• the fourth port is not in communication with the fifth port;
• the sixth port is not in communication with the seventh port;
• in the second working state, the fourth port communicates with the fifth port;
• the seventh port communicates with the sixth port;
• the fourth port is not in communication with the seventh port;
• the fifth port is not in communication with the sixth port.
