MAHLE Battery Cooling Plates Enter EV Series Production In Spain

MAHLE has started series production of MAHLE battery cooling plates for electric vehicles at its Montblanc facility in Tarragona, Spain. The production upgrade follows a double-digit million-euro investment aimed at transforming operations and increasing manufacturing capability. The plant can produce up to 15,000 units per week after full capacity expansion. The project supports growing demand for advanced thermal management solutions as electric vehicle manufacturers focus on improving battery efficiency, charging performance, and long-term reliability through optimized cooling technologies.

The upgraded production line integrates advanced manufacturing processes, including cathodic dip coating and PVC surface treatments, to improve durability and performance of battery cooling plates. The components are produced using aluminum, a fully recyclable material that helps reduce environmental impact throughout the product lifecycle. Following the adaptation of 10,000 square meters of facility space, production output will gradually increase from 1,000 units per week to 8,000 units per week by the end of 2026, strengthening the facility’s role in electric vehicle component manufacturing.

Battery cooling plates developed at the Montblanc plant are designed to maintain battery temperatures below 40°C while ensuring uniform heat distribution across individual cells. This thermal management capability helps support lithium-ion battery performance, faster charging capability, and improved operational lifespan in electric vehicles. The expansion reflects the increasing importance of efficient battery cooling technologies as automakers accelerate electrification strategies and demand reliable solutions for high-performance electric vehicle platforms.

The production initiative has received support from PERTE VEC 2, a Spanish government program focused on strengthening electric and connected vehicle development. Additional assistance has been provided by the Government of Catalonia through ACCIO. The investment highlights the strategic importance of localized electric vehicle component manufacturing in Spain, supporting industrial transformation and advanced automotive technology development across the region.
