An interesting article, but it is missing some essential details about the wireless technology. There are several providers of Wireless charging equipment. Some use inductive energy transfer similar to what was used in the EV1 charging padals and others use a resonant inductive energy transfer that was promoted by N. Tesla.

Some readers may also be more familiar with Holo IPT a former UK wireless charging company that was recently purchased by the well funded wireless communications company, Qualcomm.

Wireless charging is a bit less efficient, but its convenience is likely to make people move much faster to EVs. The bit of power we lose to wireless is going to be nothing compared to the power we save by getting off oil.

Wireless can lose 10% of the electricity used. For a Nissan Leaf that would mean an extra 0.035kWh per mile. At ten cents per kWh, an additional cost of a third of a penny per mile.

When the technology is fully in place one will be able to be guided to an available parking spot with charging. The driver will simply park. The car will signal how much charge is wanted and the billing info. In places where charging spots are tight, the driver will get a phone message a few minutes before charging is complete so that they can move their car and free up the charger for another driver.

Chargers embedded in parking spots will minimize vandalism and theft problems. Keep maintenance to a bare minimum. Home charging spots will mean that you simply drive home and park in the correct spot.

There’s nothing not to love.

Unless you’re in the oil business….
