Dell business laptop gets wireless battery charging

From InfoWorld: Dell introduced the Latitude Z business laptop, which includes a new wireless charging technology that could eventually find its way into other Dell systems, the company said on Tuesday.

The Latitude Z can be placed on a special stand that generates an electromagnetic field to recharge laptop batteries wirelessly. The technology, which Dell calls inductive charging, takes the same amount of time to recharge laptop batteries as an AC adapter, said Steve Belt, vice president of business client engineering at Dell.

"There's a coil in the bottom of the notebook and then there's a matching coil in the stand. You set them next to each other and it generates a current that flows and charges the battery," Belt said.

This is the first time Dell has included wireless recharging in its laptops. The recharging stand must be purchased separately, however, as an optional extra. The technology could help reduce the dependency on power adapters traditionally used to recharge laptops.
