Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention is further described, figure 1 It is the principle block diagram of the automatic unlocking circuit of the electronic lock of the charging gun, including the power supply 10. The voltage value of the power supply is determined by the rated working voltage of the DC motor in the electronic lock, usually -12V (usually unlocked as a negative voltage), and the power supply can also be used for other purposes at the same time . The output of the power supply 10 is connected to the charging circuit 11, and the charging circuit includes an anti-reverse circuit and a current limiting resistor, and may also be composed of a controlled charging circuit. The output of the charging circuit 11 is connected to the supercapacitor 12. The capacity of the supercapacitor is determined by the energy required for unlocking the motor. Usually, a certain margin is required. The output of the supercapacitor is connected to ...

Abstract

The invention discloses a charged gun electronic lock power-failure automatic unlocking circuit which comprises a power supply. The charged gun electronic lock power-failure automatic unlocking circuit is characterized in that the output of the power supply is connected to a charging loop, the output of the charging loop is connected to a super capacitor, the output of the super capacitor is connected to an on-off loop, and the output of the on-off loop is connected to an electronic lock. According to the charged gun electronic lock power-failure automatic unlocking circuit, simulation components and parts are adopted wholly, cost is low, reliability is high, and anti-jamming capability is strong.

Description

technical field [0001] The invention relates to a charging gun for an electric vehicle, in particular to a power-down unlocking circuit for a charging gun containing an electronic lock, and belongs to the technical field of electrical devices for charging vehicles. Background technique [0002] When using a charging gun with an electronic lock to charge an electric vehicle, the electronic lock in the charging gun is in a locked state. If there is a sudden power failure during charging, the charging gun will not be able to be pulled out, which brings great trouble to actual use. . [0003] In order to ensure that the charging gun can be pulled out from the charging port after power failure, a backup power supply or energy storage circuit is required to unlock the electronic lock by switching. [0004] Manual unlocking control requires human intervention, has certain operating requirements, and is inconvenient to use. Contents of the invention [0005] The purpose of the p...
