Marelli obtains global contract from a major carmakerto supply battery thermal solutions for electric vehicles

Marelli has been awarded a significant contract from a major global carmaker to supply the Battery
Thermal Plate (BTP) for future Battery Electric Vehicles (BEVs). The solution, a key technology forthermal energy management in electric vehicles, has been developed and will be produced in-houseby Marelli.
The supply will begin in 2024, reaching approximately 5 million units over the contract period. Theagreement involves various vehicle platforms and segments for the Chinese, North American andEuropean markets.
“We are proud of this important assignment, which further strengthens our collaboration with global
carmakers on technologies that are key to optimizing thermal energy management of vehicles” said
Shuji Kobayashi, President of Marelli’s Green Technology Solutions business. “Through oursolid experience and comprehensive portfolio, we support OEMs in achieving the most efficientsolutions for electric, hybrid and internal combustion engine vehicles, adapting to their specific needs
to co-create with our customers their vehicles of tomorrow."
Effective thermal management of the battery is essential to ensure performance and efficiency infully electric vehicles, where the battery is the only energy source available. Thermal management
impacts battery life, vehicle driving range, propulsion system performance and fast charging
capability, and is key to maintaining a comfortable cabin environment. To reach maximum efficiency,
the battery must always remain within a specific optimal temperature range under all external
temperature conditions (hot/cold), while meeting the needs of the cabin and propulsion systems.
To achieve this, Marelli’s Battery Thermal Plate uses the ‘Dot Dimples’ design, which guarantees anoptimized heat exchange. Thanks to specific paths of the thermal flows, this solution stabilizes thetemperature of the battery cells and provides excellent temperature uniformity.
It also allows for an extremely flat product that requires limited space, ensuring an easy integration
and assembly within the vehicle. The production technologies and materials used for this solution
guarantee high durability and quality.
Furthermore, Marelli’s in-house testing laboratories and simulation capabilities allow to quickly adapt
the dimple design technology to the needs of each customer, for different types of batteries andgeometries. The solution is therefore highly customizable, going from small to extra-large size.

This project is the result of a global development, thanks to Marelli’s worldwide R&D centers, andthe production will be located in China, Mexico and Romania.
In addition to the Battery Thermal Plate, Marelli offers a complete range of solutions for the control,
management and optimization of the heat balance of all vehicle systems, thanks to its provenexpertise in key heat exchange technologies for different types of propulsion systems.
