    • A safety supervisory module (SSM) of an electric vehicle charging station that controls flow of current from the electric vehicle charging station to an electric vehicle. The SSM includes a set of two or more processors to control operation of a contactor control circuitry of the SSM to open and close a set of contacts of a set of power supply lines to control flow of current from the charging station to an electric vehicle. Each processor independently determines whether an unsafe condition exists and asserts a relay enable signal to the contactor control circuitry only when an unsafe condition does not exist. The contactor control circuitry generates a current to energize a relay to close the set of contacts responsive to the relay enable signal being asserted by each and every processor of the set of processors, and inhibits closure of the set of contacts or opens the set of contacts to prevent electricity from flowing between the charging station and an electric vehicle when any of the set of processors is not asserting the relay enable signal.
    • 电动车辆充电站的安全监控模块(SSM),其控制从电动车辆充电站到电动车辆的电流流动。 SSM包括一组两个或更多个处理器,以控制SSM的接触器控制电路的操作,以打开和关闭一组电源线的一组触点,以控制从充电站到电动车辆的电流流动。 每个处理器独立地确定是否存在不安全状况,并且仅在不存在不安全条件时才向接触器控制电路断言继电器使能信号。 接触器控制电路产生电流以使继电器通电,以响应于该组处理器的每个处理器断言的继电器使能信号来闭合触点组,并且禁止该组触点闭合或打开该组触点 以防止当该组处理器中的任何一个处于未确认继电器使能信号时在充电站和电动车辆之间流动的电力。
