Cummins to manufacture LFP batteries for commercial vehicles in Spain
US motor specialist Cummins announces the construction of a battery factory in Spain. Under its Accelera by Cummins brand, LFP battery packs for commercial vehicles will be manufactured there. The plan includes a modular 102-kWh system with a voltage of up to 840 volts for buses and trucks.

Accelera is a brand specialising in zero-emission technologies under the US-based engine and energy technology group Cummins. Under the management of this subsidiary, a battery production operation is now set to be established in Europe. At this month’s IAA Transportation, the company announced its intention to manufacture batteries based on its Advanced LFP battery platform at a new facility in Spain. These packs are said to be modular 102-kWh systems with a voltage of up to 840 volts. Cummins has not yet disclosed the exact location of the production site in Spain.
The announcement does not come as a complete surprise. At Busworld Europe 2025, Cummins outlined its battery plans for Europe in broad terms. Additionally, its subsidiary Accelera is already involved in a joint venture with Daimler Truck and Paccar in the US (Amplify Cell Technologies) to produce battery cells for commercial vehicles in the US state of Mississippi. Accelera by Cummins, Daimler Truck and Paccar are jointly investing “two to three billion dollars” there. However, the start of production at that site was recently delayed from 2027 to 2028. Nevertheless, the initiative demonstrates that the US manufacturer is seriously pursuing diversification into the battery industry.
While the US plans explicitly involve battery cell production, Cummins remains vague about its European intentions. It is unclear whether the Spanish facility will focus solely on assembly or if battery cells will also be manufactured there. (The electrive editorial team has submitted a corresponding inquiry to the manufacturer but has not yet received a response.)
What is clear is that in the US, the joint venture has brought on board EVE Energy, a Chinese specialist in the production of LFP battery cells. EVE holds a ten per cent stake in Amplify Cell Technologies, serves as a technology partner and contributes its expertise in the development and manufacturing of battery cells. Since Cummins has not announced any partners for Europe, it is more likely that the focus there will be on establishing pure assembly operations using supplied cells. After all, in addition to the know-how, the investments required for cell production are substantial. However, as mentioned, this has not yet been confirmed.
Regarding the battery packs themselves: Accelera’s website provides an overview of four pack variants (1T to 4T). The 1T is a very flat, single-layer ‘half-voltage pack’ with dimensions of 2 m x 62 cm x 14 cm and a nominal energy content of 51 kWh. The 2T, 3T and 4T packs, on the other hand, are ‘full-voltage packs’ with the aforementioned 102 kWh capacity and up to 840 volts. Their formats differ: the 2T pack, with its two layers, is structured similarly to the 1T but is twice as tall. The 3T and 4T have a smaller footprint but are taller. The 3T consists of three layers, while the 4T has four. All packs are said to have a lifespan of 4,000 cycles and can be charged from 10 to 80 per cent in 25 minutes. According to media reports, the batteries feature a “cell-to-pack” architecture, eliminating the module level.
Amy Davis, President of Accelera and Components, commented on the plans for Spain as follows: “We’re seeing growing demand for battery-electric solutions in the European commercial vehicle market, and our customers are looking for partners who can help them scale with confidence. Manufacturing in Spain strengthens our ability to support customers locally, while positioning us for long-term growth in the region.”
