The standard–officially called SAE J2954–governs inductive charging (wireless) systems up to 11 kilowatts and allows for streamlining between charging systems and cars from different manufacturers. The task force that wrote the standard has been working on it since 2007. They say the systems are now achieving grid-to-battery efficiency of 94 percent, and the standard is an important step toward autonomous cars being able to park and charge themselves. It clearly has large implications for the parking industry as wireless infrastructure is adopted.
