Power supply device and method for detecting non-contact state of load connected to power supply device |
摘要 |
A power supply device includes a battery, positive and negative-side contactors and a controller. The battery supplies power to a load. The positive-side contactor is serially connected to the positive side of the battery, and the negative-side contactor is serially connected to the negative side of the battery. The controller determines whether the load connected to the output sides of the positive-side contactor and the negative-side contactor is in a connected or non-contact state. The controller includes a voltage detecting circuit that detects the capacitor voltage of a capacitor connected to the output sides of the positive-side contactor and the negative-side contactor, and a determination circuit that compares the detected voltage with a predetermined voltage and determines the connected state of the load.
