Developed with an investment of €300m ($352m), the site has been designed to assemble one battery system every 45 seconds, which translates into around 1,200 units a day and as many as 300,000 systems a year.
The plant occupies 64,000m² within the Martorell complex.
According to the company, this latest phase of development is part of a wider transformation of Martorell, which is described as the Volkswagen Group’s third-largest production site in Europe.
The factory currently accounts for roughly 25% of vehicle manufacturing in Spain, with a stated target of reaching a maximum annual capacity of 600,000 vehicles in the future, of which up to 300,000 could be battery-electric models.
Seat and Cupra CEO Markus Haupt said: “The opening of this battery system assembly plant is a turning point in the history of Seat and Cupra. Today we see how our ambition becomes a reality: we are ready to produce 100% electric made-in-Spain cars that will make electric mobility accessible across Europe.”
The project is included within a wider €3bn programme to electrify the Martorell site.
It sits within a broader €10bn investment plan in Spain by Seat, Cupra, the Volkswagen Group and partners, linked to vehicle and component production.
Battery systems assembled at the plant will be transferred to the vehicle assembly workshop via an automated route using a 600m bridge.
The building is fitted with 11,000 solar panels on its roof, which are expected to generate around 70% of the power required for the battery assembly processes.
Seat and Cupra are said to be playing a central role in the Volkswagen Group’s Electric Urban Car Family programme, which covers four electric models from three brands to be built in Spain.
In addition to the Cupra Raval and Volkswagen ID. Polo at Martorell, the programme includes production of the Skoda Epiq and Volkswagen ID. Cross at the Volkswagen Navarra plant.
Volkswagen Brand CEO and Seat and Cupra supervisory board chair Thomas Schäfer said: “Four years ago, we made a historic investment to establish Spain as a key location and European benchmark for electromobility.
“Today, with the opening of this battery system assembly plant in Martorell, we are beginning a new chapter for the Volkswagen Group, for Spain and for Europe.”
