Qi (/ tʃ iː / CHEE) is an open standard for inductive charging developed by the Wireless Power Consortium.It allows compatible devices, such as smartphones, to receive power when placed on a Qi charger, which can be effective over distances up to 4 cm (1.6 in). [1]
The first specification of this time reached a maximum of 125 A with up to 500 V. The typical Chademo charging stations allowing for 50 kW direct current became the basis for the term fast charging. When the Nissan Leaf came around in 2010, having a range of up to 160 km (100 miles), the concept of an actual fast charging networks was developed.
Powerline networking is a network that can be set up using a building's existing electrical wiring. For electric vehicle charging, the SAE J1772 standard plug-in electric vehicle charger also requires HomePlug Green PHY to establish communications over a powerline before the vehicle can begin to draw any charging power.
[2] [3] Quick Charge requires both the power supply and the device being charged to support it, otherwise charging falls back to the standard USB ten watts. Quick Charge 2.0 introduced an optional feature called Dual Charge (initially called Parallel Charging), [4] using two PMICs to split the power into 2 streams to reduce phone temperature. [5]
USB Battery Charging (BC) defines a charging port, which may be a charging downstream port (CDP), with data, or a dedicated charging port (DCP) without data. Dedicated charging ports can be found on USB power adapters to run attached devices and battery packs. Charging ports on a host with both kinds will be labeled. [52]
WEMO, a subsidiary of Belkin, are a series of products from Belkin that enable users to control home electronics remotely. The product suite includes electrical plugs , motion sensors , light switches , cameras, light bulbs , and a mobile app .
The IEC 62196-2 Type 2 connector (sometimes referred to as Mennekes for the German company that designed it) is used for charging electric vehicles using AC power, mainly within Europe, Australia, NZ and many other countries outside of North America. The Type 2 connector was adopted as the EU standard in 2013, with full compliance required by 2025.
Other mobile phone power supply and charging standards have been implemented in other parts of the world (e.g., Korea and China). Proposals for a global/industry-wide mobile phone charging solution have also been promoted by the International Telecommunication Union (ITU) and by industry organizations GSMA and OMTP. The ITU and the GSMA/OMTP ...
