Innovative High Efficient Thermal Management System, coordinated by Saint jean Industries

InnoTherMS objectives

To optimise the energy efficiency of electric vehicles, design choices can no longer be made on the basis of isolated components (engine, battery, passenger compartment, etc.). These decisions must therefore be made for the vehicle as a whole.

In this case, the InnoTherMS project aims to propose an innovative systems approach to thermal management for 100% electric vehicles.

The aim of the InnoTherMS project is therefore to increase the range of electric vehicles by 10% by improving the overall thermal management of the vehicle.


  • A new system architecture incorporating new technologies for energy recovery and storage and the use of innovative materials.
  • Optimum management of thermal energy by interconnecting the various circuits. The approach takes into account: the use, storage and optimal and intelligent distribution of thermal energy.
  • An adaptive and connected control strategy for optimal system control and fast, accurate energy distribution.
  • An industrial approach with a link between energy performance and the cost of solutions to provide manufacturers with a range of solutions that are sufficiently mature for rapid deployment and integration in vehicles.

Results of the InnoTherMS project

  • Design, development and virtual validation of an innovative thermal management system to combine thermal comfort and energy efficiency.
  • Multi-platform concept validated on real-life use cases, considering vehicle types with several simultaneous thermal control requirements (e.g. food transport vehicle).
  • Overhaul of the thermal management system and deployment of an intelligent thermal flow control strategy. This will result in a 1% increase in the range of electric vehicles.

Business profits

  • Technical development of the EV chain with an optimised architecture for the thermal management of electric vehicles.
  • Modelling of the thermal management of the vehicle with the virtual study of numerous cases. This will lead to a reduction in development costs by reducing the number of tests on real prototypes.
  • Broadening the partners’ areas of expertise, giving them a competitive edge and opening the door to new activities related to electric mobility.

Monitoring the InnoTherMS project

  • The thermal management unit from the InnoTherMS project is showing promising results: +13% autonomy. The proof of concept has been virtually validated, and the project is now closed. A potential +30% autonomy is estimated via additional studies on the control strategy.
  • To move on to the next phase of the project, the development of a prototype representative of the solution developed should be launched for integration in a vehicle. Testing and validation in an operational environment would confirm the reliability and effectiveness of such a system.
