Control circuit of electronic lock of charging gun

Abstract

The invention discloses a control circuit of an electronic lock of a charging gun. The control circuit comprises a relay, an energy storing capacitor and an output interface, the relay comprises a coil, a first single-pole double-throw contact and a second single-pole double-throw contact, and the positive pole wiring end of the coil is connected with a power positive wire; the negative wiring endof the coil is connected with an electronic lock control wire, the output interface comprises three output terminals, and the first output end is connected with the common terminal of the first single-pole double-throw contact; the second output terminal is connected with the negative pole of the energy storing capacitor, the positive pole of the energy storing capacitor is connected with the common end of the second single-pole double-throw contact, and the third output terminal is separately connected with the ground and the non-common end of a normally-closed contact. The control circuit can be applied to existing magnetic latching electromagnetic locks and impulse-type electromagnetic locks, when the control circuit is in the power-off condition, and charging is stopped, different types of electronic locks can be unlocked timely, it can be ensured that the system is safe, manual unlocking is not needed, control circuits of two types of electronic locks are combined into one, the cost of a control panel is reduced, and the control circuit can be more conveniently used.

Description

technical field [0001] The invention relates to the field of charging guns, in particular to a control circuit for an electronic lock of a charging gun. Background technique [0002] The electronic lock of the charging gun of the charging pile is very important for the whole charging process. The charging gun has direct contact with people from the preparation of charging to the end of the final charging, so the safety of the charging gun is very important, and the electronic lock of the charging gun is very important for the charging process. Ensure the safety of charging. There are currently two ways to control the electronic lock of the charging gun on the market, one is the magnetic holding electronic lock, and the other is the pulse electronic lock. The advantage of the magnetic holding electronic lock is that the electronic lock will be disconnected immediately when the power is off, but the disadvantage is that it needs to be powered for a long time. The advantage o...

The advantage of the magnetic holding electronic lock is that the electronic lock will be disconnected immediately when the power is off, and the disadvantage is that it needs to be powered for a long time

The advantage of the pulse electronic lock is that it does not need to be powered for a long time, and its disadvantage is that it needs to manually disconnect the electronic lock when the power is off, which is not easy to use, so it is necessary to improve it.
