Porsche is considering several locations in its home state of Baden-Württemberg for the production of battery cells for electric cars, according to unnamed sources within the company.
The planned factory would be able to produce a capacity of 100 megawatt hours a year, which would enough battery cells for roughly 1,000 cars.
Production is to start in 2024, according to Automotive News Europe sister publication Automobilwoche.
As recently as June, there was talk that the factory would probably be built in Tübingen.
In addition to Tübingen, Gärtringen and a location near Heilbronn are also in the running, according to the sources.
The Stuttgarter Zeitung and the Stuttgarter Nachrichten newspapers had previously reported on Porsche’s plans.
According to the papers, the Porsche management board intends to make a decision in the next few weeks.
The sports-car maker announced in June that it wanted to produce high-performance battery cells on a small scale together with a partner.
According to its previous statements, Porsche will invest a high double-digit million sum in the new company.
In July, Germany's BASF announced it had been chosen as the exclusive partner to develop high-performing lithium ion batteries for electric vehicles with Cellforce Group, a joint venture between Porsche and Customcells.
Several European automakers are making substantial investments in battery production as they seek to develop competitive batteries at home.
The localized production of batteries would also free them up from potential supply chain disruptions or other foreign production dependency issues.
Volkswagen Group CEO Herbert Diess recently said enough capital is available to pull off the automaker's ambitious plan to build six large battery factories across Europe with partners by the end of the decade.
The six European factories will have joint production capacity of up to 240 gigawatt hours a year, with the first 40 gWh coming from Northvolt starting in 2023.
Meanwhile, Ford’s battery venture with SK Innovation will extend into Europe with a global EV plan calling for 240 gWh of battery cell capacity, equal to about 10 plants.
Toyota also plans to spend nearly $14 billion on batteries, including solid state, by 2030, while simultaneously expecting to slash the cost of batteries by half in the second half of this decade.
