Tesla Motors and BMW have opened discussions to clear a way to promote the use of electric cars.

“Both companies are strongly committed to the success of electromobility and discussed how to further strengthen the development of electromobility on an international level,” a BMW spokesman said in a statement.

Tesla CEO Elon Musk said on Thursday that there had been talks with other carmakers, including BMW, about how to promote the use of electric vehicles and how to make better use of its network of German charging stations.

German premium automakers have been keen to collaborate with Tesla. In January, Daimler CEO 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 and the new Mercedes-Benz B-Class EV.

Toyota will end its deal to buy battery packs and motors from Tesla for the Toyota RAV4 EV. Toyota has a 2.4 percent stake in Tesla.
