    摘要： A relay welding detector (72) is adapted for detecting welding fault of a relay (71). The relay (71) has a first electrical contact (711) coupled to a neutral terminal (N) of an alternating current (AC) power source (6) through a first power line (91), and a second electrical contact (712) coupled to a load (8) through a second power line (92). The relay welding detector (72) includes a signal generator (721) generating a test signal, a current transformer (722) wound with a portion of one of the power lines (91, 92) and generating an induced signal based on the test signal, and a determining unit (723) determining, based on the induced signal, whether the electrical contacts (711, 712) of the relay (71) are welded to each other.

    摘要： In the present invention, the connection between an external power supply and a unit for detecting welding of a relay is disestablished at least when a short circuit is detected, thereby preventing the short circuit from being falsely detected in the event that the short circuit and the welding of the relay can both be detected. A device for detecting welding of a relay detects welding of a relay provided to a path via which a cell is charged by an external power supply. Welding of a power-supply-side relay or a ground-side relay is detected on the basis of a current flowing disproportionately more toward the external power supply than the power-supply-side relay or ground-side relay when a control unit has deactivated the power-supply-side relay or ground-side relay during an interrupting in charging. A disconnecting switch establishes or disestablishes the connection between the external power supply and a weld-detection switch.

    摘要： A method of controlling a device having restricted movement. A controller is provided for controlling the operation of the device using a control algorithm. A normal operation control method is programmed onto the controller and is selectively activated by the controller to generate a normal control signal. A forcing control method is also programmed into the controller and selectively activates a forcing control signal. The normal operation control signal provides regular operation of the device, while the forcing control signal causes the device to operate in a manner that will correct the operation of the device when a restricted motion of the device is detected.

    摘要： A vehicle (10) includes a charging unit (110) receiving electric power supplied from an external power supply through a power feeding cable (214) connected to an inlet (112) for charging a power storage device (100); a discharging unit (120) for supplying electric power from the power storage device (100) to the power feeding cable (214) through the inlet (112); a discharge relay (122); and a charge relay (114). When ending a discharging operation, an ECU (130) outputs an opening instruction to the discharge relay (122) and determines based on the state of a power line (ACL1, ACL2) during output of the opening instruction whether the discharge relay (122) is welded or not. When starting the discharging operation, the ECU (130) outputs a closing instruction to the discharge relay (122) and does not determine during output of the closing instruction whether the discharge relay (122) is welded or not.

    摘要： A feed control device (1) includes a contact device (RY), an output detector (22,23,24), a contact weld sensor (20), and an alarm device (LP2). The output detector (22,23,24) is configured to detect the presence of power feeding into the side of an electrically-powered car (100) from an external power supply (PP). The contact weld sensor (20) is configured to sense that the contact device (RY) is welded based on a detection result of the output detector (22,23,24) if detecting the presence of power feeding from the external power supply (PP) to a feed line (L1,L2) for the contact device (RY) when a state signal representing charge permission is not entered. The alarm device (LP2) is configured, if the contact weld sensor senses that the contact device (RY) is welded, to indicate the occurrence of weld to the outside.
