    摘要: A driving apparatus for an electromagnetic valve comprises a conduction control circuit and a current-limit-value setting circuit. The conduction control circuit turns on and off an FET so that a conduction current flowing through the electromagnetic valve has a magnitude equal to a predetermined current limit value while a microcomputer is outputting a driving signal to the conduction control circuit. The predetermined current limit value is set at a first current limit value during a first predetermined period starting at a point of time the microcomputer outputs the driving signal. When the predetermined first period has lapsed, the predetermined current limit value is switched to a second current limit value for a second period. The second limit value is smaller than the first current limit value. A first off-time of the FET for attaining the first current limit value is set to be shorter than a second off-time of the FET for attaining the second current limit value. Alternatively, a first on-time of the FET for attaining the first current limit value is set to be shorter than a second on-time of the FET for attaining the second current limit value in the second period.

    摘要: An EVSE controller generates a pilot signal and sends the pilot signal to a vehicle. A resistance circuit is connected to a control pilot line through which the pilot signal is transmitted, and is configured to be capable of reducing the potential of the pilot signal to a prescribed potential in accordance with a state of the vehicle. A pull-down resistance and a switch are serially connected between the control pilot line and a ground line. A CPU turns on the switch when sensing an abnormality in the pilot signal.
