With HEV/EV technology (hybrid and electric vehicles) comes new leak test requirements for the automotive industry.
All the components employed in the electric powertrains, like batteries, power electronics and electric motors, must be guaranteed for sealing according to IP specifications, in order to prevent any possible entry of water or moisture from the ambient.
Moreover all of these components have cooling circuits, either working with refrigerant gas or water glycol mixture, that are needed to remove the heat generated in the normal working conditions. Cooling circuits, cooling plates, hoses and heat exchangers must be also tested for leakage, to guarantee the long term efficiency of the cooling device or to prevent the leakage of the cooling medium that could lead to a short-circuit.
Marposs can provide a wide range of standard products and customised applications, either manual or fully automated, for the leak testing of the EV components in the complete manufacturing chain. Depending on the leak testing requirements, different solutions and technologies can be proposed:
- Wide range of electronic equipment for the leak testing with air methods (absolute pressure decay, differential pressure decay, mass flow)
- Complete customised applications for the leak testing with air methods
- Sniffing solutions with tracer gas, for the identification of the leakage points
- Global check with tracer gas in accumulation or vacuum chamber, for the highest sensitivity testing
Our long term experience in the use of these technologies allows us to provide a competent support to the customers in identifying the most convenient and reliable solution and optimizing the testing process.
A demo station for the leak testing with Helium in vacuum chamber of the Cooling Jacket of an Electric Motor is shown on our booth at the Control Exhibition.
