Ennovia supplier of e-mobility applied sciences, has launched a brand new expertise for sealing busbars, which prevents coolant leakage in hybrid and EV drivetrain purposes.
ENNOVI-SealTech can be utilized with both busbars or different interconnects to accommodate purposes resembling motors, inverters or oil pump interfaces. It affords two sealing strategies: double-walled shrink tubes or adhesive tape for difficult purposes. Each get rid of post-processing, enhancing manufacturing effectivity and design flexibility with out sacrificing sealing efficiency, in line with ENNOVI.
Each configuration is validated by way of a complete testing course of, together with thermal getting old at 150° C for 1,000 hours and thermal shock biking from -40° C to +150° C for 600 15-minute cycles, in accordance with the EN 60068-2 commonplace. A leak take a look at can be carried out to confirm sealing integrity.
Using shrink tubing or tape permits ENNOVI-SealTech to adapt to nearly any busbar form and design specification. The expertise is appropriate with a variety of metals and plastics, together with copper, aluminum, PA66, PBT, PC and others.
“Managing busbar interfaces in EVs the place coolant is current on one facet and a dry, electrically strong connection is required on the opposite facet, presents a number of challenges,” mentioned Dominik Pawlik, Product Portfolio Director for Energy Interconnects at ENNOVI. “Typical sealing strategies, resembling potting or utilizing rubber O-rings or gaskets, incur the excessive value and time for secondary processes and/or points with leakage over the lifetime of the meeting—ENNOVI-SealTech overcomes all these limitations.”
