MUNICH: Charging an electric car away from home can be an exercise in uncertainty — hunting for that one lonely station at the back of a rest area parking lot and hoping it’s working.

In Europe, some of the biggest automakers are out to remove such anxieties from the battery-only driving experience and encourage electric vehicle sales by building a highway network of fast-charging stations. The idea is to let drivers plug in, charge in minutes instead of hours, and speed off on their way — from Norway to southern Italy and Portugal to Poland.

Much is at stake for the automakers, which include Volkswagen, BMW, Daimler and Ford. Their joint venture, Munich-based Ionity, is pushing to roll out its network in time to service the next generation of battery-only cars coming on the market starting next year. They’re aiming to win back some of the market share for electric luxury car sales lost to Tesla, which has its own, proprietary fast-charging network.

Despite a slower-than-expected start, Ionity CEO Michael Hajesch told the Associated Press in an interview he’s “confident” the company will reach its goal of 400 ultrafast charging stations averaging six charging places each by 2020.

The idea is “to be able to drive long distances with battery electric vehicles, across Europe and to have the same experience at each station, meaning a very easy and comfortable customer journey,” Hajesch said, speaking at the company’s Munich headquarters near the 1972 Olympic stadium.

The idea is to break electric cars out of the early adopter niche, in which they are charged slowly overnight at home and used for short commutes.

“The sites we are looking for are really the A-sites,” he said, “directly at the autobahn. Not down the road, not driving 5 kilometers into the next industrial area and finding a charging station somewhere, without light, or any amenities around, but right at the autobahn.

“If you’re going from Hamburg to Munich, because it’s a weekend trip to friends, typically you do not have much time,” he said. So what counts will be “the speed of recharging your vehicles, and at the same time finding maybe some amenities: maybe a coffee, getting a newspaper or whatever.”

Ionity opened its first station April 17 at a rest stop off the A61 highway near the small town of Niederzissen, 30 miles south of Bonn in western Germany. The six high-speed chargers are operating in “welcome mode,” meaning they’re free until May 31. After that, Ionity plans to charge for the power, which it seeks to obtain from renewable sources.

Ionity has agreements for some 300 sites, working with fueling station and rest stop landlords. The average distance between stations will be 75 miles.

More charging availability is what it will take to get an environmentally aware car buyer like Rainer Hoedt, 58, to choose a battery-only vehicle. The Berlin geography teacher owns a Mitsubishi Outlander, a plug-in hybrid that combines internal combustion with a battery he can charge overnight. The battery-only range of 30 miles lets him drive emissions free for daily trips at home.

But a family vacation of more than 120 miles to the Baltic Sea was a different story.

Hoedt had to drive on internal combustion before finding a lone charging station as he approached his destination.

On the way back, he was able to charge at a rest stop, but only by asking a nonelectric car owner to move his vehicle away from the lone charging pole. A battery-only car might never have made it home.

And he couldn’t use one to visit a cousin 400 miles away.

“I looked at the option .... The infrastructure is still so bad, I just don’t want to risk that I get stranded,” he said. “Once the infrastructure gets better, that might be my next car.”
