Mercedes-Benz is going to offer wireless charging capability for their 2017 Mercedes S-Class. It will start with their S550e plug-in hybrid model. To initiate the charging process, you just need to park your car on top of the charging pad. Mercedes says their wireless charging has 90 percent transmission rate efficiency compared to charging through a cable. In other words, it will cost you more to fully charge your car. But on the positive sides, you do not have to pull cable onto the wall. The wireless charging pad can transmit up to 3.6kW. The starting price for the wireless charging pad will be announced soon.
