Audi will launch the wireless recharging in 2017

The company is working on a wireless charging system, whose market launch is scheduled for early 2017.
Audi is devoting resources to achieve progress in the field of fast charging technology, both AC and DC, for plug-in hybrid and electric vehicles. In this sense, the company is working on a wireless charging system, whose market launch is scheduled for early 2017.

The company claims that with fast charging current is virtually impossible in the private infrastructure, because the utility power is limited. In this situation, Audi notes that the wireless charging system Audi wireless charging (AWC) is a technology induction charging through AC and could be ready for launch next year.
The first generation of the AWC technology will be adapted for use at home or in parking lots in office buildings. A later version may be integrated into public infrastructure, such as asphalt roads and parking lots.

With the AWC system, energy is transferred through a plate located on the ground and connected to the mains. The board has an integrated primary coil and an inverter (AC / AC converter). Connected to a transformer single phase 16 amp outlet, the first-generation system offers a charging power of 3.6 kW, with power up to 11 kW possible in the next version.

When the electric vehicle approaches a few meters from the load plate with your Audi e-tron the AWC system contacts the vehicle via radio. The driver then sees the AWC system precise position on the screen. The load can start immediately when the electric vehicle placed above the plate, or in accordance with a timer. With Park Pilot systems that Audi is developing for use in production, the car can be positioned independently of the wireless charging system. The driver can leave the car and then start the parking procedure remotely via your smart phone.

Before charging, an integrated electric motor base plate raises the primary coil. This minimizes the distance between it and the secondary coil, which is integrated into the front section of the base of the Audi e-tron, regardless of the type of vehicle. The electromagnetic field on the plate induces an alternating current in the secondary coil of the car. A converter AC / DC reverses the current, which then passes the high voltage electrical system, where it is used to charge the battery and provides additional uses, such as heating or air conditioning when necessary. The driver can interrupt charging at any time, and automatically stops charging when the battery is full.

Audi says the most immediate step is to recharge with 150 kW DC power. With this technology, a sporty SUV concept car like the Audi e-tron quattro would be able to charge its large battery capacity of 95 kWh to 80 percent in less than half an hour, enough for a range of about 400 kilometers. A full charge, which allows more than 500 kilometers, take about 50 minutes.

Audi and other German manufacturers use the Combined Charging System (CCS) that allows electric cars to be charged with direct current (DC) and alternating current (AC) using the standard connector Combo 2.

The official solution load of the European Union, which is based on standard CCS, has already been ratified. To further promote these standards worldwide, Audi is involved in Charin initiative launched in May 2015, along with BMW, Daimler, Opel, Porsche and Volkswagen, manufacturers and PhoenixContact Mennekes connectors, and inspection authority TÜV SÜD. In China and Japan, where there are other standards (GB / T and CHAdeMO, respectively), the specific requirements of each country will be taken.

The installation of charging stations CCS has already begun in Europe and the United States. Most stations currently available on the market supports DC loads of 50 kW.
