There are several possible reasons for this:
1, because the power is too large, so the charging pile overload stop, it is recommended that the user replace the charging pile.
2, fully charged, the charging pile will stop after full.
3, it is not connected to the electric car so it is disconnected, it is recommended that the user will plug the jack tightly.
4, socket interface loose resulting in poor contact, it is recommended that the user replace the charging pile.
5, charging pile failure, it is recommended that the user replace the charging pile.
Due to the lack of voltage leading to the result of the break, slow charging, due to the lack of voltage, in the process of use will lead to the circuit disconnect phenomenon, so it is necessary to replace the charger in time, after the voltage replacement can be used normally
