An assembly includes a movable door assembly and a heating element. The movable door assembly is configured to be disposed on an exterior of a vehicle. The heating element is coupled to the movable door assembly, and is configured to receive energy from a battery disposed on the vehicle and to heat at least a portion of the movable door assembly.

A battery system includes battery cells to store electrical energy and to output electrical power. The battery system further includes a housing, a shunt, a control board, and a connector assembly. The housing includes a cavity that the shunt is disposed in and is in direct contact with, where the cavity facilitates dissipating torsional force exerted on the shunt. The control board is disposed within the housing and includes sensing circuitry to determine an operational parameter of the battery cells and control circuitry to facilitate controlling operation of the battery cells based on the operational parameter. The connector assembly electrically couples the shunt to the sensing circuitry via a spacing connector and a securing connector. The spacing connector is disposed between the control board and an inner surface of the housing while the securing connector extends through the shunt to couple to the spacing connector through the housing.

A device may include a housing including an accommodating cavity and an insertion opening configured to allow insertion of a detector into the accommodating cavity. The device may also include a locking mechanism configured to prevent the detector from leaving the accommodating cavity. The device may also include a charging assembly arranged on the housing. The charging assembly may include a charging head and an elastic element configured to drive the charging head away from a charging port of the detector.

A housing of an example of an electronic apparatus has a top surface and a bottom surface and has a flat shape, wherein a cross-sectional shape thereof on a reference plane perpendicular to the up-down direction is a circular shape. A rechargeable battery has a rectangular parallelepiped shape. The rechargeable battery is provided inside the housing so that a first long side is at an angle to a direction extending from a first position on the side surface portion at which the charging terminal is exposed toward a second position on the side surface portion that is opposite from the first position. The electronic apparatus includes at least one of a vibrator and a speaker provided at a position that is between the first long side of the rechargeable battery and a portion of the side surface portion opposing the first long side, on the reference plane.

The disclosure provides a charger, a charging device, an energy supply device and a control method of the charger. The charger comprises a housing, a charging position, a charging port and a first heat dissipation unit. The charger comprises a base and a supporting part. The supporting part is arranged on the base. The charging position is arranged on the base and distributed around the supporting part. The charging port is arranged on the charging position and matched with a battery pack. The first heat dissipation unit is arranged on the supporting part for heat dissipation of the battery pack. With the charger of the disclosure, multiple battery packs can be charged at the same time.

Multi-port power adapters. At least one example is a method including: supplying a first bus voltage to a first device by way of a DC-DC converter coupled to a link voltage; supplying a second bus voltage to a second device by way of a second DC-DC converter coupled to the link voltage; converting an AC voltage to the link voltage by way of an AC-DC converter; selecting, by a shunt regulator, a setpoint for the link voltage based on the first bus voltage and the second bus voltage; and regulating the link voltage to the setpoint by the AC-DC converter.

A charging assembly for a charging base comprises a charging end assembly detachably connectable to a connecting end assembly to form the charging base. The charging end assembly includes a charging end housing defining a plurality of first openings, and a plurality of signal terminals received in a corresponding one of the plurality of first openings. Each signal terminal includes a main body and a guide leg extending from an end thereof. Each guide leg contracting radially inward relative to an outer wall of the main body and adapted to bias a spring sheet of a lead frame and guide the outer wall of the main body to be inserted into contact with the spring sheet.

An embodiment of the present disclosure is directed to a method for identifying an opening/closing state of a cover of a charging box. The method includes: utilizing an earphone to receive a detection information sent by the charging box; utilizing a second processor to execute a first identification policy according to the detection information to generate an identification result; and utilizing the second processor to determine a cover state information of the charging box according to the identification result. The detection information is used to represent the cover state information of the charging box.

A computer implemented method for managing charge availability of a charge unit (CU) to obtain charge for a battery of an electric vehicle (EV) is provided. The CU includes a computer for processing at least part of the method and for communicating with a server over a network. The method includes receiving, by the server, status information from the computer of the CU. The method includes sending to the computer of the CU instructions to make a reservation for the CU. The reservation is for a user account that has requested a desire to charge the battery of the electric vehicle of the user at the CU or another CU. The method includes sending, by the server, a confirmation for the reservation to the user account. The confirmation is viewable via a device having access to the server via the user account. The method includes sending, by the server, a data regarding a time of availability of the CU to the user account for the reservation. The computer of the CU is configured to display a visual indicator regarding the reservation of the CU.
