Conductive Wireless Charging
Conductive charging is electrical conductor, conductive power transfer that replaces the Wire, conductive wires between the charger and the charged device with Current collector#Contact shoe, conductive contacts. Charging infrastructure in the form of a board or rail delivers the power to a charging device equipped with an appropriate receiver, or pickup. When the infrastructure recognizes a valid receiver it powers on, and power is transferred. Phones and other electronic devices Conductive power transfer uses electrical contacts to connect a power supply to a portable device in order to transfer energy. The technology is sometimes called "conductive wireless charging". The need for a conductor-to-conductor connection between the power supply and the device is the main difference from inductive charging and other forms of wireless charging. The conductive power supply, often a charging base or pad, detects when a compatible receiver or pickup is placed on it. Contact-based access ...

Swedish Transport Administration
The Swedish Transport Administration () is a government agency in Sweden, controlled by the Riksdag and the Government of Sweden. It is responsible for long-term infrastructure planning for transport: road, rail, shipping and aviation. It owns, constructs, operates and maintains all state-owned roads and railways and operates many car ferry services. The agency is a member of the Nordic Road Association. For shipping and aviation, it only does planning and purchasing unprofitable traffic. Trafikverket does not do practical physical work to construct or maintain roads or railways, because that is done by separate companies which Trafikverket write contracts with and pay. History A special committee oversaw the effectiveness of the Swedish transport agencies during 2008 and 2009. A conclusion was reached that there would be significant gains compared with the then-present situation if a new agency responsible for long-term planning of the transport system for road, rail, maritime a ...

Wireless Power Transfer
Wireless power transfer (WPT; also wireless energy transmission or WET) is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electric power source, electrically powered transmitter device generates a time-varying electromagnetic field that transmits power across space to a receiver device; the receiver device extracts power from the field and supplies it to an electrical load. The technology of wireless power transmission can eliminate the use of the wires and batteries, thereby increasing the mobility, convenience, and safety of an electronic device for all users. Wireless power transfer is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or are not possible. Wireless power techniques mainly fall into two categories: Near and far field. In ''near field'' or ''non-radiative'' techniques, power is transferred over short distances by magnetic fields using inductive coupling ...

Inductive Charging
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 vehicles, power tools, electric toothbrushes, and medical devices. The portable equipment can be placed near a charging station or inductive pad without needing to be precisely aligned or make electrical contact with a dock or plug. Inductive charging is named so because it transfers energy through inductive coupling. First, alternating current passes through an induction coil in the charging station or pad. The moving electric charge creates a magnetic field, which fluctuates in strength because the electric current's amplitude is fluctuating. This changing magnetic field creates an alternating electric current in the portable device's induction coil, which in turn passes through a rectifier to convert it to direct current. Finally, the direct current ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charging Station
A charging station, also known as a charge point, chargepoint, or electric vehicle supply equipment (EVSE), is a power supply electrical device, 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). There are two main types of EV chargers: Alternating current (AC) charging stations and direct current (DC) charging stations. Electric vehicle batteries can only be charged by direct current electricity, while most mains electricity is delivered from the power grid as alternating current. For this reason, most electric vehicles have a built-in AC-to-DC converter commonly known as the "onboard charger" (OBC). At an AC charging station, AC power from the grid is supplied to this onboard charger, which converts it into DC power to recharge the battery. DC chargers provide higher power charging (which requires much larger AC-to- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battery Charger
A battery charger, recharger, or simply charger, is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging after the battery has been fully charged and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type. Simple chargers of this type must be manually disconnected at the end of the charge cycle. Other battery types use a timer to cut off when charging should be complete. Other battery types cannot withstand over-charging, becoming damaged (reduced capacity, reduced lifetime), over heating or even exploding. The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the stat ...

Elways
An electric road, eroad, e-roadway, or electric road system (ERS) is a road which supplies electric power to vehicles travelling on it. Common implementations are overhead power lines above the road, ground-level power supply through conductive rails, and dynamic wireless power transfer (DWPT) through resonant inductive coils or inductive cables embedded in the road. Overhead power lines are limited to commercial vehicles while ground-level rails and inductive power transfer can be used by any vehicle, which allows for public charging through a system for power metering and billing. Of the three methods, ground-level conductive rails are estimated to be the most cost-effective. Government studies and trials have been conducted in several countries seeking a national electric road network. Korea was the first to implement an induction-based public electric road with a commercial bus line in 2013 after testing an experimental shuttle service in 2009, but it was shut down due to agin ...

European Committee For Electrotechnical Standardization
CENELEC (; ) is responsible for European standardization in the area of electrical engineering. Together with ETSI (telecommunications) and CEN (other technical areas), it forms the European system for technical standardization. Standards harmonised by these agencies are regularly adopted in many countries outside Europe which follow European technical standards. Although CENELEC works closely with the European Union, it is not an EU institution. Nevertheless, its standards are "EN" EU (and EEA) standards, thanks to EU Regulation 1025/2012. CENELEC was founded in 1973. Before that two organizations were responsible for electrotechnical standardization: CENELCOM and CENEL. CENELEC is a non-profit organization under Belgian law, based in Brussels. The members are the national electrotechnical standardization bodies of most European countries. Agreement types Members The current members of CENELEC are: Austria, Belgium, Bulgaria, Croatia, Cyprus, the Czech Republic, Denmark, Est ...
