Marelli iTMM. It’s time for a change in thermal management

The iTMM was created from the automotive vocation of Marelli, with its Italian roots, and the expertise of Japan’s Calsonic Kansei, which welcomed it into its constellation four years ago.

iTMM from Marelli is conceived for solving a crucial point of the electric vehicles

Marelli ‘s integrated Thermal Management Module (iTMM) is a solution that enhances the efficiency and performance of electric vehicles through optimized energy management and thermal control. It achieves this by modularizing water-cooled heat exchangers, such as the chiller or water-cooled condenser, and integrating them with a smart valve arrangement. The iTMM incorporates a combined valve that can manage up to six channel combinations, allowing for efficient connectivity between the three systems: the electric powertrain, the battery cooling system, and the cabin thermal management system. By exploiting the synergies among these systems and sharing components, it reduces the complexity of the overall system. The primary goal of the device is to ensure ideal cooling of the electric powertrain, which is crucial for maintaining its optimal performance and reliability. Effective cooling helps in managing the heat generated during operation and prevents any overheating issues. Additionally, the iTMM enables high safety standards by efficiently regulating the temperature of the battery, which is a critical component of electric vehicles.

And what about charging?

Another benefit of the iTMM is its ability to facilitate ultra-fast charging of the battery. By efficiently managing the thermal conditions during charging, the iTMM optimizes the charging process, enabling faster charging times and enhancing the overall convenience for the vehicle owner. In summary, Marelli’s integrated Thermal Management Module (iTMM) combines water-cooled heat exchangers with a smart valve arrangement to enhance the energy management, cooling efficiency, battery safety, fast charging capabilities, and cabin comfort of electric vehicles. By leveraging the synergies between these systems and reducing system complexity, the iTMM contributes to the overall performance and user experience of electric vehicles.

And more advantages, such as efficiency, weight, size

The iTMM offers improvements in efficiency, particularly in severe weather conditions and low temperatures, which can result in increased driving range of electric vehicles. According to Marelli is by up to 20% when combined with a heat pump system in winter conditions. By integrating multiple functions into a single module, the iTMM reduces the number of parts required in the overall system. This leads to a smaller size and lighter weight, providing carmakers with advantages in terms of simplicity during assembly and greater flexibility in designing the vehicle’s architecture. The module is designed to meet the latest market requirements, including the capability for ultra-fast charging with pre-conditioning. Moreover, the iTMM complies with On-Board Diagnostics standards. OBD is a system that monitors and detects malfunctions in various vehicle components and systems, ensuring compliance with emissions regulations and facilitating easier diagnostics and repairs.

Summarizing

In summary, the iTMM offers improved efficiency in severe weather conditions and low temperatures, resulting in an increased driving range when combined with a heat pump system. Its integrated design reduces the number of parts, leading to smaller size, lighter weight, and cost competitiveness. The module also meets market requirements such as ultra-fast charging with pre-conditioning and compliance with OBD standards, enhancing vehicle performance, safety, and regulatory compliance.
