[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electric vehicles with electrical energy, enabling them to store enough electricity to support their operation. As an important charging device for electric vehicles, DC charging piles have the advantages of fast charging speed, high efficiency conversion and high intelligence. The detection and fault diagnosis of charging piles play an important role in the production, operation and maintenance of charging piles. Through regular maintenance and care, the stability and reliability of charging piles are ensured, providing strong support for the popularization and development of electric vehicles. The existing charging module fault diagnosis device basically meets the needs, but there are still certain shortcomings. First, the high temperature generated by the internal equipment and circuits of the existing fault diagnosis device cannot be ventilated and dissipated in time when in use, which is easy to cause damage to the equipment or fuse of the circuit.
