US 2025/0167496 A1 · MAGNETIC LOCK FOR CHARGING ELECTRIC VEHICLE AND OPERATING METHOD THEREOF

Abstract

A magnetic lock for charging an electric vehicle and an operating method of the magnetic lock are provided. The magnetic lock includes a voltage conversion circuit, a detection circuit, and a magnetic attraction circuit. The voltage conversion circuit receives a first voltage from a power supplying connector and converts the first voltage into a second voltage and a third voltage. The detection circuit is driven according to the second voltage, provides a first control signal according to a first status signal from the power supplying connector, and provides a second control signal according to the second status signal from the power supplying connector. The magnetic attraction circuit uses the third voltage to generate a magnetic attraction force according to the first control signal. The power supplying connector is fixed to a charging port of the electric vehicle by the magnetic attraction force.
