The Consumer Electronics Association is trying to set a baseline for interoperability for chargers using magnetic coupling. One spec will target connections of less than 1 cm from coil to coil while another will address a 2-6 cm distance. The group will also try to define power efficiency and standard nomenclature for different technical approaches. The committee has said they will look at all the technologies that could provide wireless charging such as optical, RF and conductive as well as inductive approaches.
Smartphone apps for car functions and controls are a high priority for car makers now as the activity in this area has taken off quickly. Wireless charging is another point of integration and convenience to smartphone users. Although Toyota did not seem to think it is a high priority at this point, most car makers are working in this direction.
