Devices, methods and software for automated electrical connector positioning for electric vehicle (EV) charging are provided. Using, for example, the disclosed automatic charging device, a method for charging an EV includes determining receipt of an EV-side electrical connector to a charging zone of an EV charging environment. The method includes actuating a charger-side electrical connector from an initial position outside of the charging zone to a final position inside of the charging zone. The final position corresponds to the charger-side electrical connector matingly engaged with the EV-side electrical connector.

A battery system includes a rechargeable energy storage system and a battery controller. The rechargeable energy storage system has a rapid charging mode and a discharging mode. The battery controller is electrically coupled to the rechargeable energy storage system and is configured to store multiple charging tables that contain multiple charge current limit entries, where each charging table corresponds to a unique one of multiple initial state-of-charge values, determine a starting state-of-charge value of the rechargeable energy storage system in response to entering the rapid charging mode, select up to two charging tables in response to the starting state-of-charge value of the rechargeable energy storage system being adjacent to up to two of the initial state-of-charge values, and control a charging current provided to the rechargeable energy storage system based on the charge current limit entries in the up to two charging tables as selected.

A portable wireless charging system may include a charging dock station; one or more portable charging units; a connecting piece having a plurality of connecting units; a charging surface; and a plurality of charging slots to charge the portable charging unit, wherein one side of the connecting piece is attached to one side of an electronic device that is being charged, and the other side of the connecting piece attaches to the portable charging unit; and the connecting units are configured to secure the electronic device and the portable charging unit to increase a charging efficiency when the electronic device is being charged.

A modular charging and power system for generating and supplying electrical power to electric vehicles, hybrid electric vehicles, other manned and unmanned remotely operated vehicles, drones, robotics, marine and aerospace vehicles, equipment, or apparatus, portable power units, propulsion systems, and other electrically powered systems. The modular charging and power system comprises a racking system for retaining one or more interchangeable power modules. Each power module comprises a generator driven by a power unit, a compressor to deliver high-pressure driving fluid to the power unit, and a battery bank. Electrical power generated by the generator powers the compressor, the battery bank, and/or an external electronic device or system.

An article management system utilizes an electric cart which may autonomously move, automatically and easily managing articles and ensuring the convenience of delivery service by the automation of article delivery.

The present disclosure provides a battery charging apparatus and a battery charging protection control method. A power adapter in the battery charging apparatus performs data communication with a charging control circuit; when the power adapter determines that overvoltage and/or overcurrent occurs in the direct current output by a communication interface of the power adapter, the power adapter notifies the charging control circuit to drive a controller in the electronic device to switch off a communication interface of the electronic device and switches off the direct current output automatically; when the charging control circuit determines that overvoltage and/or overcurrent occurs upon receiving output voltage and output current of the power adapter, the charging control circuit notifies the power adapter to switch off the direct current output and drives the controller in the electronic device to switch off the communication interface of the electronic device.

Provided is a robot system. The robot system includes a guide rail, a slider configured to move along the guide rail, a first source disposed the slider to move together with the slider, a rotation arm configured to rotate by the first driving source, and a vehicle service robot installed the rotation arm to move by the rotation arm.

A power receiving and feeding apparatus is provided which includes a connector coupled to a power receiving and feeding outlet of an electric motor vehicle, a connector moving unit that moves the connector in a lateral direction and a vertical direction, and a position determination unit that determines a position of the power receiving and feeding outlet of the electric motor vehicle based on a position information of the electric motor vehicle and a vehicle information of the electric motor vehicle. The connector moving unit is caused to move the connector at a position higher than a predetermined height in the lateral direction and then in the vertical direction to align the connector to the position of the power receiving and feeding outlet so as to couple the connector to the power receiving and feeding outlet.

An apparatus is provided for charging a first storage battery and a second storage battery electrically connected together in series includes a first Kelvin connection, a second Kelvin connection and a third Kelvin connection coupled to the storage batteries. At least two of the Kelvin connections are configured to charge at least one of the first and second batteries. A charging source configured to selectively couple a charge signal to a storage battery through the Kelvin connections. A switching device selectively couples the charging source and measurement circuitry to at least two of the first, second and third Kelvin connections. A microprocessor selectively controls the switching device, charges the batteries, and measures a parameter of the batteries as a function of the charging signal applied to the batteries.
