Techniques for managing a distributed control system for a motor control switch are described. A request to implement a first controller for a motor control switch is received. Embodiments determine a plurality of functional modules for the first controller. Each of the plurality of functional modules comprises an instance of computer logic configured to perform a respective function. A respective Motor Control Function Set (MCFS) for performing the respective function of each of the plurality of functional modules is determined. One or more of a plurality of configurable hardware blocks are allocated to each of the plurality of functional modules. Embodiments configure each of the plurality of configurable hardware blocks based on the MCFS of the functional module to which the respective configurable hardware block is allocated. The configured plurality of configurable hardware blocks is executed as a distributed system to control the motor control switch.

Systems and methods of distributed and dynamically configurable motor control

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.

A measurement module receives crosstalk compensation factors that include distance factors based on respective distances of a current sensor of the module from respective current sensors of other measurement modules and phase difference factors based on respective differences between the phase of a source current measured by the module and respective phases of source currents measured by the other modules. The module monitors messages reporting current measurements transmitted from the other modules connected to a broadcast bus, of current measurements made by respective current sensors of the other modules measuring other respective source currents. The module determines a reported current that is computed as a function of current measurement by the module's current sensor, reported current measurements monitored from the other modules, and the received crosstalk compensation factors. The module transmits the determined reported current over the broadcast bus to the other modules and a central controller.

Multi-device current measurement crosstalk compensation

An electrical device includes a housing that is intended to be mounted on a rail, and a monitoring and/or control module including a printed circuit board. In the configuration in which the electrical device is mounted on the rail, at least one ground terminal of the printed circuit board is permanently electrically connected to the rail by elastic mechanical bearing on and direct electrical contact with a connecting element, itself elastically mechanically bearing on and making direct electrical contact with the rail or with an elastic blocking member for elastically blocking the housing on the rail.

A method of performing temperature-based diagnostics for motor starters within a physical grouping of motor starters is performed by determining a presently expected temperature operating range for each starter based on measuring operating temperatures of the starters; measuring their current draws, and evaluating the temperature and load draw data in light of compensation values assigned for the known power ratings of the starter and the starter's physical location within the grouping. With the presently expected temperature operating range of the starter determined, and the periodic monitoring of starter temperatures, when an individual starter's temperature exceeds its expected range, a diagnostic warning will be issued for that starter and/or for the control panel itself as a guide for preventative maintenance. Alternately, the warning may be issued for an unexpected temperature rise for a given rise in current draw, or for values exceeding an expected rate of temperature change.

An EVSE is equipped with voltage and current monitors to monitor V and I values over the time of charging. Normal V & I charging values for EV charging have been previously established and plotted as a threshold curve. During present charging, the V and Z values are plotted and compared to the threshold values and the slope of the V/I curve. If present value of V is less than the threshold value, or drops over time, or the Z value increases over time; current (I) to the EV is reduced and a new V/I curve is plotted. Slope of the new V/I curve is compared to the threshold and also checked for change of slope over time. If the new V/I curve slope is greater than the threshold slope, or is changing over time, corrective action is taken.

An adapter which can be retrofit onto the downstream end of a standard Electric Vehicle Supply Equipment connector is used to control power consumption of an Electric Vehicle charging facility by intercepting the Control Pilot Signal going to the Electric Vehicle and issuing a new Control Pilot Signal to the Electric Vehicle which is particularly tailored for the present use, requirements and limitations of the delivery system capability. The adapter has wireless communication capability, requires no wiring to and from the Electric Vehicle Supply Equipment, is independent of any proprietary designs of the Electric Vehicle Supply Equipment and adds no constraints or requirements to the Electric Vehicle Supply Equipment.

A system and method for evaluating and altering, if necessary, the potential for a cyber security attack on an individual embedded device located on a local network assumed to be protected from outside cyber threats. In a first level of potential exposure the system attempts to send an outgoing message to a known IP address on a network outside the local network. If the outgoing messages are confirmed as received the embedded device has access to outside networks. In a second level of potential exposure the known outside IP address attempts to send an incoming message to the embedded device. If the incoming message is received the embedded can be accessed from an external network.

The present invention provides a method of using a current transformer for a temperature sensing device. The method determines the temperature of the current transformer's secondary winding by injecting a DC current into the secondary winding, measuring a voltage across the secondary winding, calculating the resistance of the secondary winding from the voltage induced into the secondary winding by the injected DC current and determining the secondary winding temperature by calculations or a comparison with verified resistance/temperature combinations.

A dynamic digital filtering system for detecting electrical noise in a discrete I/O circuit. The dynamic digital filtering system has a controller for monitoring the logic signal produced by a logic device monitoring a remote I/O device. The logic device includes a circuit for dynamically adjusting the impedance across a power terminal and a terminal receiving a binary signal from the I/O device. Upon a change of state of the monitored logic signal the controller commands the impedance adjusting circuit to momentarily change its input impedance to determine if the binary signal responsible for the monitored change of state of the logic signal was true or false. If the monitored logic signal does not change state during the momentary change in impedance the binary signal will be verified as 'true'. If the monitored logic signal does change state during the momentary change in impedance the binary signal will be considered as 'false'.
