An electric vehicle supply equipment (EVSE) is provided with an integrated arc fault detection circuit interruption (AFCI) device to supply electricity to an electric vehicle (EV) being a load. The EVSE comprises a coupler and an AFCI device including: a controller including a processor and a memory, circuitry and computer-readable firmware code stored in the memory which, when executed by the processor, causes the controller to: detect an arcing level of arcing between the coupler and a charge port of the EV or any other series or parallel arcing within the EVSE, compare the arcing level to a threshold level to determine a hazardous nature of arching, and analyze the arcing level to determine not only if it is currently hazardous but if it is likely to become hazardous in a near term and recommend repair or replacement of the coupler and the charge port before damage occurs.

Standalone or networked electric vehicle supply equipment (EVSE) to detect and stop arcing before it becomes dangerous

An electronic circuit breaker provides waveform data wirelessly and alters a breaker code wirelessly. The breaker comprises a transceiver to wirelessly transmit information including waveform data, a microcontroller including a processor and a memory and computer-readable firmware code stored in the memory which, when executed by the processor, causes the microcontroller to: monitor in real-time breaker functional parameters to determine parametric modifications, wirelessly transmit the information that was saved previously in the electronic circuit breaker about the one or more breaker functional parameters to a remote device with a graphical user interface, alter a breaker algorithm after analyzing load data of problematic electrical loads in a mobile application (APP) of the remote device to treat the problematic electrical loads as normal and safe and test the computer-readable firmware code with a problematic electrical load to make sure the electronic circuit breaker doesn't still trip on the problematic electrical load.

Real time monitoring and parametric modifications for electronic circuit breakers through a remote device

A branch circuit thermal monitoring system comprises a housing and an electrical power distribution sub-system. The housing includes a plurality of thermal modules each connected with a thermal sensor assembly of a plurality of thermal sensor assemblies. The housing further includes a module rack wherein each of the thermal modules is installed on the module rack. The housing further includes a main controller configured to communicate with the thermal modules. The thermal modules are configured for individually monitoring corresponding identified connection points of interest with the attached thermal sensor assemblies such that the thermal modules and the thermal sensor assemblies provide continuous temperature monitoring of the corresponding identified connection points of interest. The thermal sensor assembly is configured to be directly applied to a connection point of interest thus avoiding any additional mounting assembly. The electrical power distribution sub-system is coupled to the thermal modules.

Branch circuit thermal monitoring system for continuous temperature monitoring by directly applied sensors

An electrical panel meter system may include a controller and a plurality of meter modules. Each meter module may be configured to monitor, read, and store at the meter module electrical data related to electrical power provided to a respective branch circuit of the electrical panel meter system. The controller may be configured to issue a read command simultaneously to each meter module and to store a timestamp indicative of the issuance of the read command. The controller may also be configured to issue a send command sequentially to each meter module to transmit its stored electrical data reading. The controller may further be configured to append the stored timestamp to each received electrical data reading to create a timestamped electrical data reading suitable for use in power quality analyzes. Methods of timestamping electrical data sampled in an electrical panel meter system are also provided, as are other aspects.

Apparatus and methods for timestamping electrical data in a panel meter

An electrical panel meter system may include a plurality of meter modules housed in an electrical panel enclosure. Each meter module may be configured to sample electrical readings related to electrical power provided to a respective branch circuit of the electrical panel meter system. To field test the metering accuracy of each meter module, a field tester may be coupled to the electrical panel enclosure. The field tester may inject an electrical signal via a test conductor provided in the electrical panel enclosure. The test conductor may be coupled to each meter module. The field tester may measure an electrical parameter of the injected electrical signal and compare it to electrical readings sampled by the meter modules. A pass/fail result for each meter module may be indicated. Methods of field testing meter modules in an electrical panel meter system are also provided, as are other aspects.
