Executives from German carmaker BMW and U.S.-based Tesla Motors Inc met this week in a move which could lead to the creation of charging stations usable for different types of electric cars.

BMW and electric carmaker Tesla are seeking ways to raise the popularity of battery-powered vehicles, which consumers have shunned due to their limited operating range, the scarcity of charging stations and the time it takes to recharge them.

"Both companies are strongly committed to the success of electro-mobility and discussed how to further strengthen the development of electro-mobility on an international level," a BMW spokesman said in a statement on Friday.

BMW said the meeting had taken place on Wednesday but declined to comment in detail about the nature of the talks, or about which BMW executives had met with Tesla.

In a conference call on Thursday, Tesla Chief Executive Elon Musk said there had been talks with BMW about how to promote the use of electric vehicles and how to make better use of Tesla's network of charging stations.

Carmakers including General Motors, Ford, Chrysler, BMW, Daimler, Volkswagen, Audi and Porsche have committed to adopting a common SAE combo standard for fast-charging connectors.

Fast-charging stations allow electric vehicle owners to recharge batteries up to 80 percent in less than 20 minutes.

Today, the Chevrolet Spark and the BMW i3 for example can use the same battery recharging stations.

Tesla has, however, developed its own network of high-speed charging stations including along key autobahn routes in Germany in an effort to make electric cars viable for long-distance commuting.

Tesla's charger system can be fitted with an adapter that allows its cars, including the Tesla Model S, to be recharged on both the SAE chargers and its own system.

SHARING PATENTS

Tesla also said on Thursday that it would allow others to make use of its intellectual property in the hope of speeding up development of electric cars by all manufacturers.

Musk said this included all of Tesla's patents, including several hundred current ones and several thousand in the future.

German premium auto makers have been keen to collaborate with Tesla.

In January, Daimler Chief Executive Dieter Zetsche said the German maker of Mercedes-Benz cars was open to deepening its partnership with the U.S. firm.

Daimler holds a 4.3 percent stake in Tesla, which is already supplying it with electric motors and batteries for its Smart Fortwo electric vehicle (EV) and the new Mercedes-Benz B-Class EV.
