Anti-electric shock interlocking control method and structure for charging pile live insertion and removal

Abstract

The application discloses a charging pile live plug-in anti-electric shock interlocking control method and structure, relates to the technical field of charging pile plug-in anti-electric shock, and comprises a charging gun, the head of the charging gun is provided with a first pin and a second pin, the first pin is a power pin, the length of the first pin is greater than the length of the second pin, and the second pin is an interlocking signal pin; a charging seat, the end of the charging seat is provided with a first groove, the first groove is provided with a first plug sleeve matched with the first pin and a second plug sleeve matched with the second pin, a rack and a resistance unit are additionally arranged on the basis of the traditional long-short pin structure, mechanical resistance is applied to the rack through the resistance unit, the plug-in speed of the charging gun is restricted, the action interval of the power pin and the interlocking signal pin is prevented from being less than the signal reaction time due to rapid plug-in, and the timing logic that "the power loop is connected first and the interlocking signal loop is connected later during charging, and the interlocking signal loop is cut off first and the power loop is cut off later during disconnection" can be reliably realized.
