Porsche is leading the development of an ultra fast-charging infrastructure for Volkswagen’s next generation of electric vehicles, which includes Porsche’s own Mission E, but also Audi’s quattro e-tron and VW’s latest vehicle unveiled at the Paris Motor Show last month.

Now the German automaker confirmed working with other automakers toward the development of the technology and said that it will even work with Tesla vehicles.

Porsche says that the 800-volt charging system able to charge up the Mission E’s battery pack to 80% in about 15 minutes.

The Mission E and Volkswagen’s other next-gen EVs are coming just before the end of the decade and Porsche says that new charging stations using the ultra fast-charging infrastructure will start to be deployed around the same time.

The company is looking to work with other automakers to facilitate the rollout. CEO Oliver Blume told Top Gear yesterday:

 “We are in contact with other manufacturers and suppliers around the world to build a fast-charging network. Everybody has the same need. It sounds easy but getting the details agreed is hard. We already have the clear technical concept. It can even work with Teslas, with an adapter.”

Tesla has a significant lead with electric vehicle fast-charging. The Tesla Supercharger currently being deployed have a capacity of 145 kW – 450V at 335A – and the company’s vehicles can receive up to 120 kW or about twice the power output of all other electric cars currently available.

Yet, Porsche is talking about a system about 2x faster.

Tesla has always been opened about letting other automakers use its network, but until the Mission E and other long-range vehicles with big battery packs hit the market, it wouldn’t really be useful. Last year, Tesla confirmed that it was in talks with European automakers to allow the access to the Supercharger network.

Additionally, Mercedes CEO Dieter Zetsche, who recently launched the company’s new all-electric brand ‘EQ’, confirmed being in talks with Porsche over the charging technology.
