The electric vehicle (EV) charging system standards association CharIN has formed a new wireless power transfer task force.
The task force, which is planned to kick off its activities in early September, is aimed to drive the adoption and standardisation of wireless charging solutions for EVs globally.
Established in cooperation with association members Siemens AG, the wireless charging technology company WiTricity Corporation and German charging solution provider MAHLE chargeBIG, the taskforce is intended to seek to close existing gaps to ensure the successful integration and utilisation of wireless power transfer technology in the evolving electric mobility landscape.
The taskforce will actively work towards harmonising standards in wireless power transfer technology for charging EVs.
Defining the respective applicability of wireless charging will play a crucial role in its integration into diverse EV platforms.
The taskforce also will seek to define rigorous test procedures and certification guidelines for interoperability, in order to ensure that wireless charging solutions are reliable, efficient and compatible across different platforms.
Additionally, the taskforce will focus on clearing the co-existence of relevant technologies for wireless power transfer to foster a cohesive ecosystem for the future of EV charging.
Members of the taskforce with expertise in wireless charging technology are now being sought from both CharIN members and non-members.
Wireless charging developments
Wireless charging is becoming increasingly popular for mobile and other devices, with EVs an obvious opportunity due to the convenience it offers.
Both static and dynamic options are available, enabling charging when parked in a garage or driving on highways respectively, with the former aimed primarily at homeowners and charging station operators and the latter initially at least for trucks and other high-use vehicles such as buses and taxis.
Its use so far is limited, however, but that is set to change with wireless charging now delivering efficiencies and charging times that match or even better those of traditional plug-in chargers, according to developers such as WiTricity.
As an example of recent development, WiTricity has entered into a partnership to deliver its technology in Europe with ABT e-Line, which initially will upgrade the VW ID.4 to support wireless charging and subsequently other VW, Audi and Porsche models thereafter.
In another example, another CharIN member, the Israeli company Electreon is to equip a section of the French A10 motorway southwest of Paris with dynamic wireless charging and a stationary wireless charging station initially for fleet use.
A third CharIN member InductEV recently opened a high power wireless charging R&D centre at its King of Prussia, Pennsylvania headquarters.
In the US there also is a move to introduce a grant programme for wireless EV charging with a proposal for $250 million to be made available for its introduction on roads and bus routes, in parking areas and at airports among other locations.
