ESI Automotive Reveals How To Improve Ev Thermal Conductivity Sixfold At Major US Event

This year’s Electric and Hybrid Vehicle Technology Expo and Battery Show
will see 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
takes 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 will showcase how this sixfold conductivity
increase is enabled by ALPHA® Argomax® silver sintering technology at Booth
1301. In addition, experts from the company will hold 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 will be 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

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.”
