Abstract

The invention discloses an electric vehicle coupling thermal management system and a working method thereof. The electric vehicle coupling thermal management system comprises an internal circulation system; an outer circulation system which is in coupling connection with the inner circulation system; and a single-system double-circulation mode function is realized through system coupling between the inner circulation system and the outer circulation system. The two sets of mutually coupled thermal management systems are adopted, the performance requirements of a passenger compartment air conditioning system and a battery cooling system are met, and meanwhile, the two sets of systems can mutually provide performance supplement. The requirements of the passenger compartment and the battery in the maximum cooling load can be met, the energy efficiency ratio of a single system in operation can be increased, and meanwhile the economical efficiency of the system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle coupling heat management system and a working method thereof. Background technique [0002] In electric vehicles, the thermal management system must not only meet the needs of air conditioning in the passenger compartment, but also the needs of battery cooling. The load of the thermal management system, especially the cooling load, spans a very large range. [0003] After the vehicle is exposed to the sun in summer, people enter the vehicle, hoping that the air conditioning system can quickly cool down. [0004] When the battery is fast charged, it is also hoped that the thermal management system can provide a very large cooling capacity in a short time to meet the cooling requirements of the battery during fast charging. [0005] When the vehicle is running stably, especially in spring and autumn, the load on the air conditioning of the passenger ...
