Abstract: A temperature sensor 31A for bolted connections 8A, includes a thermally conductive housing 30 having a skirt portion 62 with an opening shaped to fit on a portion of a bolted connection of a bus bar. The skirt portion of the housing is configured to be in thermal contact with the bolted connection when the skirt portion is fitted on the bolted connection of the bus bar. The temperature sensor further includes a temperature transducer 70 in thermal contact with the housing. The temperature transducer is configured to sense a temperature of the housing which relates to a temperature of the bolted connection and to output signals to a data collector 1 via wireless or wireline communication.

Abstract: A monitoring system is provided for monitoring a status of current supply through a current supply conductor 5 in an electrical housing 1. A current transformer 13 and a monitoring circuit 15 monitor the conductor 5 in the housing 1. The monitoring circuit 15 is powered by current induced in the transformer from current in the conductor. The monitoring circuit 15 is configured to output a signal on an output line 14 indicating whether the current in the conductor is on or off. The monitoring circuit 15 is connected to at least one of a display device 24 and a door interlock 8 of a door of the housing 1 to, respectively, indicate whether the current in the conductor 5 is on or off and to prevent the door 17 of the housing 1 from opening when the signal on the output line 14 indicates that the current is on.

Abstract: Systems, methods and devices for monitoring an electric vehicle charging station (EVCS) are disclosed. A security system is disclosed for monitoring an EVCS having an electrical connector for electrically coupling to an electric vehicle. The security system includes a camera for recording images of a surrounding area of the EVCS. A sensor detects objects near the EVCS and/or detects removal of the electrical connector from the EVCS. A controller, which is operatively coupled to the camera and the sensor, is configured to: receive sensor signals output from the sensor; responsive to the sensor signals indicating that an object is near the EVCS or the electrical connector is removed from the EVCS: direct the camera to record images of the surrounding area of the EVCS; output to a user the images of the surrounding area of the EVCS; and, receive user command signals to control the EVCS and/or the security system.

Abstract: An EVCS equipped with an accelerometer to detect seismic events. Upon sensing a catastrophic environmental event, the EVCS is automatically disconnected from the main utility power source. A controller powered by a backup or alternate power source inside the EVCS monitors the seismic activity, and upon sensing the seismic event is over, the EVCS automatically performs a startup check. If utility power is present and the self-check passes, the EVCS resets and provides power from the main utility to the charging connector. If the EVCS is operable but utility power is unavailable, the EVCS switches to a generator or a UPS. The EVCS can provide multiple power outlets, including USB outlets, and emergency lighting. The EVCS can also be retrofitted or constructed with a communications interface for communicating status and operational information following a seismic event.

Abstract: A docking station for stowing an electrical connector adapted to connect a power source to a re-chargeable battery in a vehicle powered at least partially by the battery. The connector has a first end connected to a power cable for coupling the connector to the power source, and a second end that includes multiple first electrical terminals adapted to engage mating second electrical terminals in a receptacle. The second end also includes a protruding latching element adapted to engage a cooperating latching element in a receptacle for latching the connector to the receptacle. A stowing receptacle adapted to receive the second end of the connector when the connector is not in use includes an elongated recess adapted to receive the protruding latching element when the protruding latching element is located anywhere along the length of the elongated recess.
