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 energy ...
The standard allows compatible devices, such as smartphones, to charge their batteries when placed on a Qi charging pad, which can be effective over distances up to 4 cm (1.6 in). [2] The Qi standard is developed by the Wireless Power Consortium. [1] As a universal, open standard Qi-enabled devices are able to connect to Qi chargers from any ...
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 ...
Radio Equipment Directive (2022) European Parliament adopted new rules to make USB type-C the common charging standard for small electronic devices by the end of 2024. The Directive (EU) 2022/2380 is a directive of the European Parliament and the European Council which was formally adopted on 23 November 2022 amending Radio Equipment Directive ...
Resonant inductive coupling or magnetic phase synchronous coupling[4][5] is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. [5] A resonant transformer of this type is often used in analog circuitry as a bandpass filter.
The Combined Charging System (CCS) is a standard for charging electric vehicles. It can use Combo 1 (CCS1) or Combo 2 (CCS2) connectors to provide power at up to 350 kilowatts (kW) (max 500 A). [ 1 ] These two connectors are extensions of the IEC 62196 Type 1 and Type 2 connectors, with two additional direct current (DC) contacts to allow high ...
Common external power supply and the USB-A and USB Micro-B ends of the detachable cable. The common external power supply (Common EPS) was a European Commission (EC) specification for a universal charger for smartphones sold within the European Union. The specification included the use of a USB Micro-B connector and adherence to the USB Battery ...
Austin K9 FFW, with 'house' body. Fitted For Wireless (FFW) and Fitted For Radio (FFR) were British Army designators for vehicles equipped to carry radio equipment. Although many of these vehicles were dedicated 'radio vans' and had complex and expensive radio sets installed, the intention was also that general purpose vehicles could be issued in 'FFW' state with the low-cost but time ...
