The invention provides a magnetic attraction lock for charging an electric vehicle and an operation method of the magnetic attraction lock. The magnetic attraction lock comprises a voltage conversion circuit, a detection circuit and a magnetic attraction circuit. The voltage conversion circuit receives a first voltage from the power supply connector and converts the first voltage into a second voltage and a third voltage. The detection circuit is driven according to a second voltage, provides a first control signal according to a first state signal from the power supply connector, and provides a second control signal according to a second state signal from the power supply connector. The magnetic suction circuit generates a magnetic suction force by using a third voltage according to the first control signal. The power supply connector is fixed to the charging port of the electric vehicle through magnetic attraction force.

    本发明提供一种用于对电动载具进行充电的磁吸锁以及磁吸锁的操作方法。磁吸锁包括电压转换电路、侦测电路以及磁吸电路。电压转换电路接收来自于供电连接器的第一电压,并将第一电压转换为第二电压以及第三电压。侦测电路依据第二电压而被驱动,依据来自于供电连接器的第一状态信号来提供第一控制信号,并依据来自于供电连接器的第二状态信号来提供第二控制信号。磁吸电路依据第一控制信号来利用第三电压产生磁吸力。供电连接器通过磁吸力将供电连接器固定于电动载具的充电端口。
