POWER CONVERSION SYSTEM AND CONNECTOR

摘要

PROBLEM TO BE SOLVED: To provide a power conversion system capable of detecting and notifying a problem on a circuit breaker mounted on an electric vehicle.SOLUTION: A power conversion system 10 has a detection circuit 32 that detects a problem on a second circuit breaker 43 which is inserted in a power supply path 5 on an electric vehicle 4 so as to detect a problem on the second circuit breaker 43 mounted on the electric vehicle 4. The power conversion system 10 has a notification section 13 that notifies the detection result made by the detection circuit 32 in a connector 3 so as to notify any problem on the second circuit breaker 43. Therefore, the power conversion system 10 allows a user to take appropriate countermeasures even when any problem such as deposition occurs on the second circuit breaker 43 mounted on the electric vehicle 4.
