It’s increasingly clear that the German prestige brands plan to launch luxury electric cars that will go head-to-head with upstart Tesla Motors and its Model S and Model X.
But a sexy, fast, comfortable, luxurious electric car will not be enough to compete effectively.
The German brands must also provide pervasive networks of fast-charging sites—the equivalent of Tesla’s Superchargers—for the times that their owners decide to take their new electric cars on longer journeys.
Now it appears that Audi plans to do just that.
The luxury volume brand of VW Group told reporters on Friday it will offer a DC fast-charging network for buyers of the production version of its Audi e-tron Quattro, which will arrive during 2018.
The battery-electric five-seat SUV with a 95-kilowatt-hour battery pack (sometimes referred to as the Q6 e-tron) was revealed as a concept in September at the Frankfurt Motor Show.
But assuming Audi can provide a luxury electric SUV with 250 or more miles of range, it still faces the need to compete with the growing Supercharger network.
Now numbering more than 1,400 outlets in 231 locations, the Supercharger fast-charging sites are part and parcel of the allure of buying a Tesla Model S or Model X.
Not only do buyers get the car itself, they also get lifetime access to any Supercharger--which will recharge the battery from 20 to 80 percent of its capacity in about half an hour, depending on how many cars are charging at once.
At a one-day presentation in Madrid of multiple advanced technologies—the carmaker called it Future Performance Day—Audi executive Reinhard Hofmann said it would offer such a network “along with other [carmakers].”
Those would be some combination of BMW, Fiat Chrysler, Ford, General Motors, Mercedes-Benz, Porsche, and Volkswagen—all of which have committed to use the CCS (Combined Charging System) protocol for fast charging.
While current CCS sites are limited to roughly 50 kW, Tesla Supercharger stations already charge at 125 kW.

The 150-kW network Audi envisions would thus be a large step up in fast charging for much larger packs than the 19- to 24-kWH packs now found in CCS-equipped cars from the Chevrolet Spark EV to the VW e-Golf.
“By the launch date,” Hofmann said, CCS “charging power will be increased to 150 kilowatts”—which would mean that even a 95-kWh pack like that of the e-tron Quattro could recharge to 80 percent capacity in less than 30 minutes.
That would provide “real long-distance capacity,” he said, for the first Audi long-range battery electric vehicle.
Even more interesting, Hofmann suggested, would be a longer-term expansion from 150 kW to as much as 350 kW.
The goal, he said, would be that battery recharging “not take any longer time than refueling”—offering “long-distance [electric] mobility with high convenience.”
Ideally, he said, such recharging would be even quicker and more convenient than standing next to your car while you refilled it with gasoline or diesel fuel.
For Audi to get to 150-kW DC fast charging, the carmaker must work toward several concurrent advances.
First, existing committee work to define a CCS charging standard that goes as high as 150 kW must reach consensus and issue a published standard—or be very close to doing so.
Second, Audi and some combination of the rest of the CCS partners must agree on how a U.S. network of such sites would be funded and built over the next three to five years.

The challenge is that while Tesla alone planned, funded, and built its Supercharger network, multiple carmakers with possibly conflicting agendas and product plans must agree how to proceed to build a network that will initially benefit only some of them.
Moreover, there will have to be consensus on how such a network will be branded. Multiple Audi executives were quite clear, as hydrogen fuel-cell expert Rene von Doorn put it, that VW Group is “a carmaker, not an energy supplier.”
“We are not interested in [providing] any fueling infrastructure, except for demonstration projects,” he said.
