OG exemplary drawing
 
1. An electric vehicle thermal management system, comprising:
a first loop, a second loop, a first temperature control mechanism, a second temperature control mechanism, a conveying mechanism and a release mechanism;
wherein the first loop is configured for transmitting a first heat conducting agent, a battery and the first temperature control mechanism are respectively connected to the first loop, and the first loop transmits the first heat conducting agent to circulate between the first temperature control mechanism and the battery;
the second loop is configured for transmitting a second heat conducting agent, a driving motor and the second temperature control mechanism are respectively connected to the second loop, and the second loop transmits the second heat conducting agent to circulate between the second temperature control mechanism and the driving motor;
the conveying mechanism is respectively connected to the first loop and the second loop;
the release mechanism is connected to the first loop, and a release port of the release mechanism faces the battery.
 
15. A battery thermal management method using the electric vehicle thermal management system according to claim 1, comprising:
the first loop transmits the first heat conducting agent to the first temperature control mechanism, and the first temperature control mechanism cools down the first heat conducting agent, the first loop transmits the cooled first heat conducting agent to the battery for heat exchange to cool the battery;
the conveying mechanism transmits the second beat conducting agent to the first loop, such that the second heat conducting agent converges with the first heat conducting agent, and the release mechanism releases the first heat conducting agent and the second heat conducting agent that are converged to the battery for occurrence of a thermal runaway in the battery.
 
17. An electric vehicle comprising the electric vehicle thermal management system according to claim 1.
