The memory is configured to store multiple codes or program instructions. The processing unit is configured to execute the codes or program instructions to control the FM processing circuit to search for FM channel(s).

A charging inlet assembly for an electric vehicle includes a housing having a power connector including AC terminals and DC terminals. An AC terminal assembly is coupled to the housing and includes AC bus bars electrically connected to corresponding AC terminals at a separable mating interface. A DC connector is mechanically and electrically connect to the DC contact of the DC connector at a separable mating interface.

A socket tester device includes an electrical plug that is to be inserted into an electrical socket, a tester circuit electrically coupled to the electrical plug, a sound emitting device, a communication device, a processor, and a memory. The tester circuit outputs one or more signals indicating a wiring condition of the electrical socket into which the electrical plug is inserted. The memory stores instructions that, when executed by the processor, cause the processor to receive the one or more signals indicating the wiring condition of the electrical socket into which the electrical plug is inserted, control the communication device to wirelessly transmit a first message that includes data indicating the wiring condition of the electrical socket into which the electrical plug is inserted, and control whether the sound emitting device emits one or more sounds.

This disclosure describes electric vehicle supply equipment (EVSE) connectors for synchronizing and controlling charging between multiple electric vehicle supply equipment and an electrified vehicle. An exemplary EVSE connector is connectable to a charge port assembly of an electrified vehicle and includes a first port configured to receive a first charger coupler of a first EVSE and a second port configured to receive a second charger coupler of a second EVSE. The EVSE connector further includes a control system for coordinating charging operations between the first and second EVSE and the electrified vehicle.

A combined wall outlet extender and remote control light relates to a field of lighting equipment and includes a lower cover, an upper cover arranged on the lower cover and matched with the lower cover, insert pins arranged on the lower cover, a power cord configured to connect with a light strip and arranged on a bottom portion of the upper cover, and an infrared receiver passing through the upper cover. A protective cover is arranged on the upper cover. The protective cover protects components arranged on the upper cover. A fixing pin is arranged on the lower cover. The upper cover and an upper end of the lower cover are combined to form a slot. A lampshade, button caps, USB interface through holes, and AC output port through holes are arranged on the upper cover. A main control PCB is arranged on the lower cover.

The present invention discloses a sofa USB socket including: a USB female socket including a tongue core, wherein the tongue core includes 5 pins, and the fifth pin is an ID pin; and a USB circuit including a power circuit, a filter circuit, a control chip and a buck chopper circuit, wherein the buck chopper circuit includes a transistor, and the ID pin is electrically connected with the transistor. When an external USB male plug is inserted into the USB female socket, the power circuit supplies power to the USB female socket; when the USB female socket is in an unloaded state, the fifth pin is suspended, the control chip enters a sleep state, and the USB female socket has no output voltage, which greatly reduces the no-load energy consumption, thereby being beneficial to extending the endurance time and the service life of a power supply battery.

A power supply includes a cover body, a metal plate, a metal clip, a circuit board and a housing. The metal plate is partially disposed in a first space of the cover body. The metal clip is disposed in the first space and electrically connected to the metal plate, and includes an upper spring piece, a lower spring piece and a connecting piece. The connecting piece has a fixing portion corresponding to a gap between the upper and lower spring pieces. The circuit board includes an input portion and an output portion. The input portion is disposed in the gap, and has a protruding part for engaging with the fixing portion. The housing includes an output interface and an opening communicating with an accommodating space of the housing. The cover body is connected to the opening. The output interface is electrically connected to the output portion.

A variety of active cover plate configurations with prongs configured to contact side screw terminals of electrical receptacles are described. In one illustrative embodiment, an active cover plate includes a multi-gang face plate configured to be installed over a multi-gang light switch installation, the multi-gang faceplate including at least two apertures sized to accept a manually manipulatable element of switches in the multi-gang light switch installation. Prongs extend rearward from the multi-gang faceplate around at least one of the apertures.

A power-feed connector disconnection device includes an index value detector, a starting intention determiner, and a lock-releasing unit. The index value detector detects an index value that correlates with a starting intention of a driver to start a vehicle when a power-feed connector is coupled to a power-receiving connector of the vehicle. The starting intention determiner determines a presence or absence of the starting intention of the driver based on the index value detected by the index value detector when the power-feed connector is coupled to the power-receiving connector of the vehicle. The lock-releasing unit is provided in the power-receiving connector and releases a lock between the power-receiving connector and the power-feed connector when the starting intention determiner determines that the driver has the starting intention.
