Power supply from both the host (docking station) and portable device allows for supporting the portable device with power and battery charging, as well as supporting accessories from the portable device. USB 3.0 "SuperSpeed", USB 2.0, and USB On-The-Go support file transfer and device control, as well as device-to-device intercommunication.
Wireless power transfer. Inductive charging pad for a smartphone as an example of near-field wireless transfer. When the phone is set on the pad, a coil in the pad creates a magnetic field [ 1] which induces a current in another coil, in the phone, charging its battery. Wireless power transfer ( WPT ), wireless power transmission, wireless ...
Inductive charging. The primary coil in the charger induces a current in the secondary coil in the device being charged. Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in ...
A mobile phone plugged in to an AC adapter for charging. A battery charger, recharger, or simply charger, [ 1][ 2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage, current, for how long and what to do when charging is complete—depends on the size and type of the ...
Online electric vehicle. On-Line Electric Vehicle or OLEV is an electric vehicle system developed by KAIST, the Korea Advanced Institute of Science and Technology, which charges electric vehicles wirelessly while moving using inductive charging. Segments composed of coils buried in the road transfer energy to a receiver or pickup that is ...
The standard was created to enable home automation, security, healthcare and energy monitoring applications that are battery powered. Like DECT, DECT ULE standard uses the 1.9 GHz band, and so suffers less interference than Zigbee , Bluetooth , or Wi-Fi from microwave ovens, which all operate in the unlicensed 2.4 GHz ISM band .
Charging point. A battery electric vehicle ( BEV ), pure electric vehicle, only-electric vehicle, fully electric vehicle or all-electric vehicle is a type of electric vehicle (EV) that exclusively uses chemical energy stored in rechargeable battery packs, with no secondary source of propulsion (a hydrogen fuel cell, internal combustion engine ...
A charging station, also known as a charge point, chargepoint, or electric vehicle supply equipment ( EVSE ), is a power supply device that supplies electrical power for recharging plug-in electric vehicles (including battery electric vehicles, electric trucks, electric buses, neighborhood electric vehicles, and plug-in hybrid vehicles ).
