Our vision: this business will be your key in the next decade to winning a significant market share
The zero-emission technologies that EXOES can help you with: batteries and power electronics or heat pumps.
EXOES co-develops future thermal management systems to improve their cost/benefit ratio. We are involved from the drafting of the specifications to vehicle integration.
EXOES brings you an understanding of the application for which your fluids will be used and helps you continuously improve their performance and your market share.
Each year, our clients save 30-40% in terms of development time with a high level of service and quality.
Manufacture of representative
prototypes
Manufacture of customised test
benches delivered to our customers
or used internally
Representative tests for
the automotive sector
0D, 1D, 3D simulation
correlated with test results
EXOES provides you with all its skills in thermal, mechanical, fluid, electronic and electrical engineering for a perfect integration of all components in a system.
In addition, we have developed agile processes to significantly optimize our lead times and thus help you meet the requirements of the automotive sector.
We are also solicited for the development of other thermal management systems for the following components: power electronics, electric motors, and integration of complete cooling systems in an electric vehicle (cooling circuit of the battery, electric motor, power electronics).
The customer is a European car manufacturer in the top 5 worldwide
Duration of the program: 22 months in 3 phases
Cell type: NMC > 60 Ah
Role of Exoès before the beginning of the program: participation in the drafting of the specifications, advice and sharing of experience on the definition of the evaluation and validation program of different technologies and different immersion cooling fluids. Support for decision making on the split between simulations and real tests.
The customer’s need
-Define the ideal fluid for monophasic and diphasic cooling
-Carry out an evaluation of the series cost of a complete cooling system according to different cooling architectures
-Calculate the impact of different immersion cooling architectures on the mass of a vehicle
-Design a representative battery module
–Test this module in performance
–Test the module safety with an abuse test (nail puncture test)
–Define an ageing test protocol with several fluids
–Characterize the cell to determine the maximum C-rate at a defined maximum temperature
-Design and manufacture electrical heating elements representative of the heat losses of tomorrow’s cells and assemble them into modules
-Carry out thermal performance simulations and correlate them with test bench measurements
The customer is a US based fluid manufacturer among the worldwide leaders
Duration of the program: 15 months in 2 phases
Role of Exoès before the beginning of the program: complete definition of the evaluation and validation program of different immersion cooling fluids.
The customer’s need :
-Compare the performance of different fluids for monophasic and diphasic cooling by carrying out tests on existing prototypes and test benches at Exoès
-Evaluate the series cost of a complete cooling system for a given module architecture.
-Publish a white paper for car manufacturers explaining how to fill and drain the fluid and clean the module and battery pack
-Define the sensitivity of the fluid to water absorption and pollution
-Characterize fluid mixtures and define the method for mixing and ensuring homogeneity
-Build a battery module for comparative abuse tests between different fluids
