Abstract: An electric vehicle (EV) charging system can include a plurality of charging terminals, each charging terminal comprising a charging cable configured to connect to an electric vehicle. The system can include an electrical equipment assembly physically separated from the plurality of charging terminals. The assembly can include a plurality of electric vehicle supply equipment (EVSE) loads, each EVSE load configured to supply power to a respective charging terminal to provide a charge current to an EV connected to the cable of the charging terminal. A main breaker can be connected to the plurality of EVSE loads configured to supply power to the plurality of EVSE loads and to provide fault protection to the plurality of EVSE loads to provide protection to each charging terminal. In certain embodiments, the main breaker is at least partially solid state.

Abstract: 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.

Abstract: 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.
