Can energy-storage charging piles meet the design and use requirements?
The simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
What to do in case of charging pile faults?
In case of a fault, the charging pile will display the related fault code on the charging fault record page, the fault light will be on, and the output of the charging pile will be cut off. Faults in charging piles can be reset by swiping the card. After the settlement is completed, faults will be warned and reset, and the charging pile will enter the standby state.
Why is it important to maintain the charging pile?
The importance of maintaining charging piles lies in the fact that influences by the changeable environment and ageing inner parts can cause various faults. Regular examination and maintenance are necessary during both product storage and using processes.
What happens if fault is not cleared in charging pile?
If a fault is not cleared in a charging pile, it could not work normally after started a second time. After settlement completion, faults are warned and reset, and the charging pile enters a standby state. Only after the fault has been cleared can the charging pile work by restarting.
Are piles subject to surcharge loads?
In fact, there is lack of conditions in which piles are only subjected to surcharge loads. For example, although NSF is caused by the withdrawal of the groundwater table on piles carrying a tall building, the behaviour of NSF is heavily governed by the tall building (axial load).
Can CS-LR predict smart charging pile faults based on classified data?
