Marelli has launched its new integrated Thermal Management Module (iTMM) for electric vehicles, which allows the efficient combination of the vehicle’s different thermal circuits into one single component to shape a more efficient thermal management system, ultimately increasing driving range, safety and flexibility.

An optimised thermal energy management is a key factor especially in EVs, as the cooling and heating needs of components and passengers within the car require high energy consumption. Greater efficiency can be achieved by managing and controlling properly the three systems that most affect energy usage: the e-powertrain thermal system, the battery thermal system and the cabin thermal system.

While EVs generally have a number of heat exchangers with a sole function, Marelli’s integrated Thermal Management Module modularises water-cooled heat exchangers, such as the chiller or water-cooled condenser, with a smart valve arrangement. By using this combined valve, which manages up to 6 channel combinations, the iTMM efficiently connects the three systems, exploiting their synergies and sharing components, to obtain optimized energy management. This reduces the total system complexity, while ensuring ideal cooling of the electric powertrain, high safety and ultra-fast charging of the battery and an optimal thermal comfort within the cabin.

Another improvement enabled by the iTMM is the efficiency in severe weather conditions and at low temperatures, that allows the increase of the vehicle’s driving range up to 20%, when coupled with a heat pump system in winter conditions.

The integrated system has a reduced number of parts, with smaller size and weight, ensuring to carmakers simplicity of the assembly, architecture flexibility within the vehicle and competitive system cost. The module meets all the latest market requirements, such as ultra-fast charging with pre-conditioning and compliance with OBD (On-Board Diagnostics) standards.
