Cummins will manufacture LFP batteries for commercial vehicles in Spain
U.S. engine manufacturer Cummins announces plans to build a battery factory in Spain. Under its Accelera by Cummins brand, LFP battery packs for commercial vehicles will be produced there. The system in question is a modular 102-kWh unit with a voltage of up to 840 volts, designed for buses and trucks.

Accelera is a brand specializing in zero-emission technologies, owned by the American engine and energy technology company Cummins. This subsidiary is now set to establish “battery production in Europe.” At the IAA Transportation, the company announced its intention to manufacture batteries using its “Advanced LFP” battery platform at a new facility in Spain. These battery packs are expected to be modular 102-kWh systems with a voltage of up to 840 volts. In response to an inquiry from electrive, a company spokesperson clarified that the location will be the city of Guadalajara, about 50 kilometers northeast of Madrid.
The announcement is not entirely surprising. Back at Busworld Europe 2025, Cummins already outlined its broad battery plans for Europe. Additionally, its subsidiary Accelera is already involved in a joint venture with Daimler Truck and Paccar in the U.S. (“Amplify Cell Technologies”) to produce battery cells for commercial vehicles in Mississippi. Accelera by Cummins, Daimler Truck, and Paccar are investing “two to three billion dollars” together there. However, the start of production was delayed from 2027 to 2028. Nevertheless, this initiative shows that the U.S. manufacturer is seriously pursuing diversification into the battery industry.
While the U.S. explicitly mentions battery cell production, Cummins remains vague about its plans for Europe. It is therefore unclear whether operations in Spain will be limited to assembly only or if cells will also be manufactured there. The electrive editorial team has sent a query to the manufacturer, but so far there has been no response.
It is clear that in the U.S., the three partners of the joint venture EVE Energy have brought on board a Chinese specialist in LFP battery cell manufacturing. EVE itself holds a 10 percent stake in Amplify Cell Technologies, acts as a technology partner, and contributes its expertise in battery cell development and production. Since Cummins does not name any partners for Europe, it is likely that the region will focus on a pure assembly process using supplied cells. After all, in addition to technical knowledge, investments in cell manufacturing are also substantial. As mentioned, this has not yet been confirmed.
Regarding the battery packs themselves: Accelera provides an overview on its website of four pack variants (1T to 4T). The 1T is a very flat, single-layer “Half voltage pack” with dimensions of 2m x 62 cm x 14 cm and a nominal energy capacity of 51 kWh. In contrast, the 2T, 3T, and 4T packs are “Full voltage packs” with a capacity of 102 kWh and voltages up to 840 volts. Their formats differ as follows: The 2T pack, with its two layers, is similar in structure to the 1T but twice as tall. The 3T and 4T packs have a smaller base area but are taller. The 3T consists of three layers, while the 4T has four layers. All packs are said to have a lifespan of 4,000 cycles and can reach 80% charge in 25 minutes from 10%. According to media reports, the batteries feature a “Cell-to-Pack” architecture that eliminates the module level.
Amy Davis, president of Accelera and Components, commented on the plans for Spain as follows: “We are seeing growing demand for battery-electric solutions in the European commercial vehicle market, and our customers are looking for partners who can help them expand their businesses securely. Manufacturing in Spain enhances our ability to support customers locally and also gives us a strong foundation for long-term growth in the region.”
