Abstract: A discharge detection device of the present invention is configured to be capable of detecting a discharge phenomenon via wiring, including: a noise detection section electrically connected to the wiring and configured to allow a noise component generated by the discharge phenomenon to be input via the wiring and configured to output the noise component if the noise component has a predetermined frequency or more; and an arithmetic section configured to determine whether a level of the noise component is high by comparing the level of the noise component with a threshold. The arithmetic section counts the number of occurrence of the discharge phenomenon if the level of the noise component is determined to be high, and performs a control process selected based on the number of occurrence of the discharge phenomenon.

Abstract: The present invention provides a distribution board having a main breaker and a plurality of branch breakers, the distribution board being wired to branch power supplied to the main breaker into each branch breaker, the distribution board including: a plurality of noise detection sections configured to correspond to the respective branch breakers one-to-one and each configured to output a detection signal based on a noise component of not less than a predetermined frequency generated on a secondary side of each branch breaker; and processor configured to separately receive the detection signal output from each noise detection section and determine whether the detection signal is high frequency noise at a threshold or more.

Abstract: Provided is a charging apparatus for vehicles which charges a vehicle provided with a charging control circuit via a charging cable, comprising a charging control device which controls electrical charging to the vehicle by transmitting a charging control signal to the charging control circuit on the vehicle side, a charging control signal transmission restricting device which restricts transmission of the charging control signal, and a resetting device which forcibly resets the charging control signal when said restriction on transmission of the charging control signal is withdrawn.

Abstract: An electric vehicle charger includes: a first winder unit and a second winder unit for winding and holding a charging cable having a charging connector at its end portion; and a body unit for arranges the first winder unit and the second winder unit with the distance between the first winder unit and the second winder unit set longer than the diameter of the charging cable, wherein the charging cable passes between the first winder unit and the second winder unit, and the charging cable is fixed before passing between the first winder unit and the second winder unit.

Abstract: The present invention provides a switch that can prevent a locking member from being lost, that allows easy operations of handle locking and unlocking, and that allows more secure handle locking. A switch of the present invention includes a fixed contact point, a moving contact point capable of making contact with the fixed contact point, a handle to move the moving contact point, and a locking lever to lock the handle. The handle is equipped integrally with an overhang portion. The overhang portion is formed with a notched portion. The locking lever is equipped integrally with a projecting portion. The locking lever is pressed upwardly by a spring. When the handle is at a first position, an operation of the handle is locked by engaging the projecting portion to the notched portion. When the handle is at a second position opposite to the first position, an operation of the handle is allowed by letting the projecting portion abut on a lower surface of the overhang portion.
