The drone may include a connection port carried by the drone body. The drone may include a port contact sensor carried by the drone body, the port contact sensor is configured to detect whether the battery pack is slid in to the connection port.

The present disclosure describes systems for providing electrical power that are modular, upgradable, and customizable. Systems described herein can be used to create modular, upgradable, and customizable charging stations for charging electric vehicles. In one example, a sub panel module can be electrically connected to a main input line that provides an alternating current power supply, and includes a plurality of electrical outlets, and a plurality of breaker switches Each breaker switch is electrically connected to one or more of the plurality of electrical outlets and can be electrically connected to the main input line.

A charging station for charging an electric vehicle with a housing which has a rear side and a visible side located opposite thereto, wherein between the rear side and the visible side there is formed a storage region adapted to compactly hold a charging cable provided with a charging plug. A decorative element connected to the housing and/or the charging plug and/or a stand supporting the housing is/are provided.

A charging device for charging a battery is provided, including a first housing, a channel, a fan, an electronic member, and a second housing. The first housing has an inner space. The channel passes through the first housing, and the wall of the channel separates the channel from the inner space. The fan is disposed in the channel. The electronic member is disposed in the inner space and is in contact with the wall of the channel. The second housing has an accommodating space. The accommodating space is configured to receive the battery and communicates with the channel.

A mechanical actuator and charging module for an adjustable furniture item may include a charging module, a lever, a fulcrum arm, a housing, and a connector. The charging module may include at least one charging interface. The lever may be coupled to a cable of the connector and have a user interface at a first end and a pivot opening at a second end. The fulcrum arm may have a fulcrum pin opening and may be coupled to the lever by a fulcrum pin extending through the fulcrum pin opening and the pivot opening with the fulcrum pin being configured to translate motion of the user interface in a first direction into motion of the cable in a second direction. The housing may include an electronics compartment and enclosing at least a portion of the charging module and at least a portion of the lever.

A system for mounting a wireless cellphone charger to a cellphone, including a cellphone case and a wireless cellphone charger mount. The cellphone case defines a bore and a recess disposed adjacent the bore and includes a shell and a first retention ring having a first metal plate receivable by the recess to secure the first retention ring to the shell. The wireless cellphone charger mount has a wireless cellphone charger, a second metal plate and an interface comprising a protrusion receivable by the bore. The wireless cellphone charger is securable to the cellphone case when the first retention ring is secured to the shell by aligning the protrusion and the bore and magnetically coupling the first and second metal plates.

A device for charging and discharging a battery cell includes first and second plates spaced from each other, the first and second plates being configured to press respective first and second surfaces of a battery cell locatable therebetween, and first and second pressing blocks located on the first and second plates, respectively, the first and second pressing blocks protruding from the first and second plates to face each other. The first and second pressing blocks are locatable in a space between a body and a gas pocket of the battery cell. A method using the device is also provided.

A wireless charger having coils disposed in a recess of a metallic case of the wireless charger, wherein a heat-conducting material is disposed in the recess to encapsulate the coils with the first heat-conducting material being in contact with the coils, a sidewall, and a bottom surface of the recess.

Provided is a charging system including: a second power transmission unit; a moving mechanism that moves the second power transmission unit within a moving area including prescribed ranges within a plurality of parking spaces; and a power transmission control unit that, when a first electric vehicle is parked in a first parking space as one of a plurality of parking spaces, moves the second power transmission unit into the prescribed range of the first parking space by the moving mechanism to cause the first power transmission unit mounted to a first electric vehicle and the second power transmission unit to face each other so as to transmit power to the first power transmission unit from the second power transmission unit wirelessly to execute vehicle charging processing for charging the first electric vehicle.
