ESI Automotive Revealed How To Improve EV Thermal Conductivity Sixfold At Major US Event

This year’s Electric and Hybrid Vehicle Technology Expo and Battery Show saw ESI Automotive demonstrate how new technologies such as silver sintering can help automotive OEMs achieve up to six times greater thermal conductivity of a die bond in the inverter of an electric vehicle. The event took place on September 14-16 at the Suburban Collection Showplace in Novi, Michigan, USA.

ESI Automotive is a major innovation provider that works closely with global automotive OEMs. The company showcased how this sixfold conductivity increase is enabled by ALPHA^® Argomax^® silver sintering technology at Booth 1301. In addition, experts from the company held a 40-minute presentation on Wednesday September 15, focused on three use cases showing how silver sintering is being used by automotive OEMs to improve vehicle performance and reduce total cost for ownership in EVs.

The event was the first time ESI Automotive has exhibited at a trade show following the recent acquisition of HK Wentworth Group and its Electrolube brand. The Electrolube brand adds value to ESI Automotive’s rich portfolio of solutions, thanks to its cutting-edge thermal management solutions. Electrolube will be situated within the main Expo alongside ESI Automotive, offering the latest solutions for EV vehicle batteries including TIM’s.

Working with ESI Automotive, OEMs can now access the broadest range of materials such as silver sintering materials, gap fillers, phase change materials, thermal pastes and thermally conductive encapsulation resins, among others. Across this extensive portfolio of technologies, ESI Automotive is helping vehicle OEMs reduce the risk of field failures through the development of an enhanced and more reliable final product to take to the market.

Chris Klok, director of vehicle electrification at ESI Automotive, explained: “Through the breadth of ESI Automotive, we are working with OEMs to view their designs and components at a systems level. This enables us to help them enjoy gains in range, power and reliability, through innovative technologies such as silver sintering die attach for inverters and thermal management solutions for battery packs.

“Thermal conductivity is one area where this can make a real difference and is critical for EV, since electric vehicles are more efficient if thermal conductivity in the electric powertrain is improved. ESI Automotive research has shown that silver sintering alone can produce a bulk silver bond with a melting point of 962°C and extremely high thermal conductivity, in the range of 200-300 W/m.K, compared to 26-55 W/m.K for solders.”

Chris Klok added: “As global regulations driven by climate change are pushing OEMs down the EV route and all major manufacturers are embracing vehicle electrification options, it is necessary to view traditional production lines from a systems level and identify where improvements can be made. In-creasing vehicle range, power and reliability remains a key challenge that OEMs are working hard to overcome. At this year’s Electric and Hybrid Vehicle Technology Expo and Battery Show, we’re looking forward to revealing how our recent acquisition of the Electrolube brand puts us in an even stronger position to partner with OEMs and achieve these goals.”
