Abstract: A distributed energy management method and system 100 are disclosed for managing a charge rate of an array of EVSEs 140 that share a common power source. In the disclosed method and system, control of the power sharing is distributed at the individual EVSE level. For example, each EVSE includes a communication device 540 and a controller 530. The communication device is used to receive a signal relating to a present current capacity utilization of the shared circuit, such as an indication of availability or unavailability of current capacity on the shared circuit. The controller is configured to generate a variable update interval, and initiate adjustment of the charge rate of the EVSE according to the variable update interval based on the present current capacity utilization as indicated by the received signal.

Abstract: A cable reel assembly in an electric vehicle supply equipment (EVSE) having a reel around which a cable is coiled. A shaft supporting the reel bears discs that rotate with the reel, and calipers coupled to the discs stop them and the reel from rotating. The power L1 and L2 conductors in the cable are electrically connected to the discs, and the calipers are electrically connected to the power source for the EVSE so that the calipers provide mechanical and electrical connection when actuated. Optionally, slip rings coupled to the shaft are connected to the control pilot and proximity signal conductors in the cable. Thus, during cable re traction, the control pilot and proximity signals are still provided to the EVSE, but the power conductors are decoupled from the power source. Only when the calipers are actuated to brake the discs is current flow permitted.

Abstract: A method, apparatus and computer program product resolve the problem of unbalanced loads in an EVSE cluster of multiple EVSE charging stations. A signal is provided to the EVSEs identifying which phase of the three-phase power source has the highest current. When one of the EVSEs in the cluster determines whether it is connected to an EV's on board charging device, determines whether it is already charging the connected EV, and determines whether the EVSE is using the phase that has the highest current, then the EVSE may transmit a cluster load balancing control signal as a control pilot signal to the EV's onboard charging device to adjust the charging rate of the current that the EV is consuming from the EVSE.

Abstract: A temperature sensor 120 automatically shuts down charging operations in response to a temperature increase in a charging handle 150 of an electric vehicle charging station 100. The temperature sensor is connected between a ground conductor and a high voltage conductor L1 in the charging handle. The charging handle includes a return conductor L2/N. The temperature sensor includes a thermistor R1-NTC that changes its resistance in response to an increase in temperature in the charging handle. A portion of current in the high voltage conductor is diverted to the ground conductor, instead of the return conductor, in response to the thermistor sensing a temperature increase, thereby causing a ground fault detector 160 to trip in the charging station.

Abstract: The invention provides consistent settings between local and remote parameter adjustments of both local and remote HMI. A dial (4) is superimposed on a bistable display substrate (2), having an indicator (7) configured to be manually aligned with a displayed character representing a manual setting of a parameter value for controlling local equipment. A network interface (18) is connected over a communications network (17) to a remote HMI (16), configured to receive a new parameter value for controlling the local equipment (25). A controller (14) samples the current position of the indicator (7) of the dial (4), and provides a control input signal (20) to the bistable display substrate (2) to control a display of the new parameter value in the current position of the indicator (7) of the dial (4) and to provide the new parameter value to the local equipment (25).

Abstract: A circuit measures temperature in a charging handle 150 of an electric vehicle charging station (EVSE) 100. A temperature sensor is connected between a control pilot line 115 and ground line G in the charging handle of the EVSE. The control pilot line transmits a square wave signal CP having positive and negative portions, to an electric vehicle, according to the SAE J1772 standard. A temperature monitor 300 in the EVSE, coupled to a pilot signal measurement circuit 230 in the EVSE, measures the negative portions of the square wave signal resulting from the temperature sensor conducting current in response to changes in temperature in the handle. Temperature measurement of the charging handle is achieved without significant added cost or complexity, by reusing existing components in the EVSE, with little or no modification required to EVSE electronics, and minimal modification of the handle.

Abstract: An add-on adapter 110 enables a single charging port 102 of an electric vehicle charging station 100 to simultaneously charge two electric vehicles. An adapter controller 120 determines the available charging rate offered by the charging station. Electric vehicle charging handles 150A, 150B are determined to be connected to the electric vehicles. A charge sharing control circuit 300 in the adapter controller, determines modified available charging rates to be offered for simultaneously charging the electric vehicles. The modified available charging rates are based on the connection states of the electric vehicles and the available charging rate offered by the charging station. The adapter controller controls two contactors 130A, 130B to switchably connect a charging station power socket to the electric vehicle charging handles, to provide shared power at the determined modified available charging rate to the electric vehicles, for simultaneous charging.
