The invention relates to an EV (electric vehicle) charging spot allowing complete power-off in case of non-charging. The EV charging spot comprises an EV charging post in which a transformer is provided. The primary side of the transformer is provided with a power incoming terminal; the secondary side of the transformer is provided with a device power supply terminal. The EV charging spot further comprises a power-off system; the power-off system comprises a switch-on maintaining switch system capable of automatically maintaining a switch-on state after switching-on; the switch-on maintaining switch system is provided between the power incoming terminal and the device power supply terminal; the switch-on maintaining switch system comprises a switch-on signal incoming terminal used for inputting a switch-on signal. In case of no current, the switch-on maintaining switch system allows no passage of current, complete power-off is achieved, standby energy consumption of the EV charging spot is reduced to 0, and one hundred million kilowatt hours is expected to be saved for the power grid each year.
