Corbetta, Italy- Marelli., launches 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 effective thermal energy management is critical, especially in electric vehicles, since the cooling and heating needs of the vehicles components and passengers necessitate considerable energy consumption. Greater efficiency can be achieved by appropriately regulating and controlling the three systems that most affect energy usage: the e-powertrain thermal system, the battery thermal system and the cabin thermal system.
While most electric vehicles feature a number of heat exchangers with a single function, Marelli's integrated Thermal Management Module modularizes water-cooled heat exchangers with a smart valve arrangement, such as the chiller or water-cooled condenser. The iTMM efficiently integrates the three systems, leveraging their synergies and sharing components, by using this integrated valve, which manages up to six channel combinations. This decreases overall system complexity while assuring appropriate cooling of the electric engine, great safety and ultra-fast battery charging, and optimal thermal comfort within the cabin.
Yet another advantage of the iTMM is its efficacy in severe weather and low temperatures, which allows the vehicle's driving range to be increased by up to 20% when installed alongside 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.
Alongside this innovative technology, Marelli’s Thermal Solutions division develops a full range of thermal systems to improve vehicle durability and performance, both for internal combustion engine and electric powertrains, maximizing the effectiveness through an efficient control and balance of thermal energy.
