AI Technical Summary

Technical Problem

Existing charging stations lack effective thermal management solutions, making it difficult to simultaneously meet the thermal management requirements of charging piles and charging guns, which affects equipment reliability and lifespan.

Method used

A charging system is designed, comprising a battery device, a charging connector, and a thermal management system. The system achieves heat exchange between the battery device and the charging connector through first and second heat exchange flow paths and a switching mechanism. Combined with a compression refrigeration cycle loop and a switching mechanism, multiple heat exchange loops are formed to meet different thermal management requirements.

Benefits of technology

It improves the thermal management efficiency of the charging system, reduces operating costs, extends the service life of the equipment, and enhances the flexibility and reliability of the charging system.

Abstract

A charging system for charging a traction battery of a vehicle, the charging system comprising: a battery apparatus used for storing energy and charging the traction battery by means of releasing the energy; a charging connector configured for connecting to the vehicle so as to charge the traction battery via the charging connector; and a thermal management system, which comprises a first heat-exchange flow path, a second heat-exchange flow path and a first switching mechanism. The first heat-exchange flow path comprises a first heat exchanger used for exchanging heat with the battery apparatus; the second heat-exchange flow path comprises a second heat exchanger used for exchanging heat with the charging connector; and the second heat-exchange flow path is connected to the first heat-exchange flow path by means of the first switching mechanism, such that by means of a switching operation performed by the first switching mechanism, the second heat-exchange flow path is in communication with the first heat-exchange flow path via the first switching mechanism, or the communication relationship established between the second heat-exchange flow path and the first heat-exchange flow path by means of the first switching mechanism is cut off.
