Wireless charging in Mercedes-Benz S550E from next year

The Mercedes-Benz S550e is going to get improvements for the next year. One of them is going to be wireless charging system, the first commercial application of a Wireless Electric Vehicle Charging (WEVC).

A Tier 1 power electronic company will supply the S class plug-in hybrid, same one that has licensed Qualcomm Halo technology that allows EVs and Plug-in Hybrid EVs (PHEV) to charge automatically, without the need to plug in. It uses resonant magnetic induction to transfer energy wirelessly from a ground-based pad to a pad integrated into the vehicle. Qualcomm and Formula E were working together to use the race series as a platform for showcasing Qualcomm’s advanced automotive technologies, advancing Formula E’s status as a leader in high-tech sustainable motorsports.

The process comparable to conductive charging’s 90-percent efficiency rating, and it is improving as power increases. Currently, the system runs at 3.6 kW, which is fine for a plug-in hybrid with, a small battery like the S550e and its 8.7-kilowatt-hour lithium-ion unit.

EVs will charge while driving, after Qualcomm’s adapts technology for roadways

Qualcomm’s officials are announcing future development of wireless charging plans. At the moment Halo system uses a pad that transfers energy to a laptop-sized receiving pad on the bottom of the vehicle. Around 800 volts is at the disposal for performance applications, but most of the time voltage about 400 volts. Commercial system has a max rate of 11 kW, but Qualcomm has achieved as high as 125 kW charging big buses in the U.K.  Numerous charging at lower speeds is, according to the company the best application of the technology, but on the other hand it would oppose the necessity for 150-kW chargers like Supercharger network that Tesla is using.

In the future EVs can be charged during the drive, after Qualcomm’s adapts technology for roadways. Its engineers currently working on an inductive charging system, and the hope is that soon it will be shown practicability of the future infrastructure for charging on road. It will allow that future cars would have smaller, lighter batteries requiring less energy to start and stop. Furthermore, the cars of the future would have object detection to sense when a live beings or other subjects are about to enter the field.
