Volkswagen has big plans for its future electric cars, and it’s just sent a clear signal. The German automaker has purchased $48-billion worth of electric-vehicle batteries from suppliers.

Fortune reported last week that the supplier deals bring VW much closer to its goal of purchasing nearly $60-billion worth of EV batteries. The automaker will need them; VW wants to sell 3 million electric cars per year by 2025.

To put the $48-billion figure into perspective, the massive purchase is nearly what all of Tesla is currently worth.

VW CEO Herbert Diess said the automaker wants to see Europe establish its own battery cell production, which echoed comments from Germany’s economy minister just this week. The official told a local German newspaper that the country’s automakers must invest in electric cars and battery production or face the consequences. Right now, the United States and Asia are poised to handle much of the world’s battery-cell production.

Diess also said the automaker will offer 25 battery-electric cars and 20 plug-in hybrids by 2020. Of course, the executive speaks for VW entirely, which covers the Volkswagen, Audi, and Porsche brands, notably. Audi will launch its first electric SUV later this year, and Porsche is on track to produce a production version of the Mission E concept in 2020. Meanwhile, VW will roll out a range of ID-branded electric cars.
