Why is charging module important in DC charging pile?

Conclusion Charging module is the key to the safe and reliable operation of DC charging pile. The DC charging pile to maintain stable operation state for the charging module fault state identification results, timely development of solution strategies.

How accurate is fault detection in DC charging pile?

It is necessary to accurately judge the fault state of the charging module of DC charging pile in order to ensure the safe and reliable operation of DC charging pile. However, the fault signal processing of the fault detection method is poor, resulting in low fault detection accuracy.

Can Ana-LSTM neural network predict charging pile battery life?

In this study, the improved anti-noise adaptive Long Short-term memory (ANA-LSTM) neural network was used to extract fault characteristics, thus achieving the life prediction of charging pile batteries and providing reference for the status detection of charging piles. However, the signal data was not effectively processed by this method.

What are the parts of a DC charging pile?

The DC charging pile consists of charging module, main controller, power meter, card reader, air switch, main relay and other modules. The charging module is the core part of the DC charging pile, which is mainly composed of four parts: main circuit, control circuit, sampling circuit and driving circuit.

What are the possible faults of DC charging pile?

During the operation of DC charging pile, faults are easy to occur, mainly including communication faults, charging gun faults, charging module faults, etc. Among the possible faults of the DC charging post, the charging module failure rate is extremely high.

Can multiple concurrent faults be detected in DC charging pile charging module?

There may be multiple concurrent faults in the actual DC charging pile charging module fault state. Therefore, the fault detection performance of different methods is analyzed to verify whether the proposed method can accurately detect faults in the case of multiple concurrent faults in the context of this actual problem.
