SAE TASKFORCE J2954 NEARS STANDARD ON WIRELESS CHARGING
Published at 27.01.2012 in Alternatives, Technology
The SAE Taskforce on wireless charging and positioning of electric vehicles (SAE J2954) is progressing, and is slated to have a final draft of the guideline this year, according to the Society of Automotive Engineers, International (SAE).The objective of the taskforce is initially to create a guideline for demonstration projects and design verification and later standardize in 2015 with field confirmation.
Wireless Charging enables the customer the ability to have “transparent” recharging of plug-in electric vehicle—EV, combustion engine (IC) PHEV, fuel cell (FC) PHEV—through a seamless connection to the EVSE charger and automated charging process. For WPT [wireless power transfer], essentially the customer does not have to do anything except park the vehicle in the right spot. The integration of DSRC communications (specified by SAE Hybrid/DSCR committees) allows WPT increased interconnect ability over present conductive communications with V2Infrastructure assisting in location of available chargers, an automated secure charging and billing and options such as connectivity with smart grid.Since launching in late 2010, the taskforce has now grown to comprise six subteams: Alignment and communications (in coordination with SAE Hybrid Communications and SAE DSRC committees and the US Department of Transportation (DOT)); Testing and validation; Verification of wireless charging regarding performance, safety, interoperability and communication; interoperability; WPT frequency determination; and Bus wireless charging.
There is heavy involvement from industry and government in the effort. WPT suppliers include Conductix-Wampfler; Evatran; HaloIPT; KAIST (Korea); Momentum Dynamics; LG; OLEV; Qualcomm; Samsung; SEW; and WiTricity. Other infrastructure companies include Better Place, NRG Energy and Southern California Edison.
Auto OEMs participating include Audi; BMW; Chrysler; Coda; Daimler; Fisker; Ford; GM; Honda; Mitsubishi; Nissan; Phoenix; and Toyota. Bus manufacturers Volvo and Proterra are also participating.
