One of the fundamental elements of this new stage is the adoption of the Volkswagen Group unified cellA common battery solution will be used extensively across different models, brands, and segments within the consortium. This standardization strategy facilitates large-scale production, enhances flexibility between plants, and helps reduce manufacturing costs—key to expanding the reach of electric vehicles to a wider audience.

The battery system assembled in Martorell is based on the architecture MEB+, an evolution of the group's electric platform for compact and urban vehicles. This concept incorporates a design cell-to-pack which allows for better use of available space and, in certain configurations, uses cells with lithium-iron-phosphate chemistry (LFP), an alternative that offers good durability and can help to lower the final cost of the vehicle.

In addition to the unified cell, the system integrates the so-called E-BoxThe E-Box, considered the "brain" of the battery, manages the overall operation of the system, from temperature and charge level control to communication with the rest of the vehicle. It is manufactured at the El Prat plant, which has transitioned from producing traditional gearboxes to specializing in key elements of the electric vehicle value chain, a clear example of [the company's commitment to innovation]. industrial reconversion Within the group.

In the first phase, the battery cells assembled in Martorell come from the plant of Salzgitter (Germany)Subsequently, the supply will shift towards the future Sagunt gigafactory (València), which the Volkswagen Group is launching through PowerCo and which aims to become a strategic node within the European battery chain.

The adoption of this common technology aims to guarantee speed, scale and flexibility in the electrification of the consortium's various brands in Europe. The idea is for Martorell to play a central role in the production of battery systems for a new generation of electric urban vehicles, both for CUPRA and Volkswagen, with the capacity to adapt to the needs of different markets and regulations.

Renewable energy and skilled employment at the Martorell plant

The battery assembly plant stands out not only for its production capacity, but also for its integration of sustainability and resource efficiency criteriaThe building houses some 11.000 solar panelswhich cover approximately 70% of the electricity consumption associated with the assembly process. This contribution of renewable energy helps to significantly reduce the carbon footprint of production.

Along with the energy component, the facility has a system of rainwater collection and storage with a capacity similar to that of three Olympic swimming pools. This infrastructure allows for the reuse of water in various internal processes, reinforcing the water efficiency strategy in a context where the sustainable management of this resource is gaining increasing importance in industry.

In terms of employment, the plant provides jobs for around 500 specialized peoplewith profiles ranging from highly trained operators in automated processes to engineers and quality or maintenance technicians. The transformation towards electromobility is driving the need for new skills, both in the field of software and electronics and in the field of energy storage system management.

Seat and CUPRA emphasize that the investment in this new battery plant is part of a broader commitment to a sustainable and competitive production in Spain.
