Traditional battery cooling takes the form of a plate, usually made of aluminum, with embedded channels for the coolant. The battery cells, which are usually surrounded by a metal sleeve, and the cooling plate are rigid. Direct contact, for instance due to manufacturing tolerances, always results in an air gap and thus poor thermal conductivity.…

DeeDee Smith, Luigi Marino, Brian Baleno Solvay Materials A significant challenge for eMotor 800 Volt designers is to design smaller and more compact eMotors. Successfully doing so allows for the potential to reduce the mass of both the eMotor and battery pack. A new slot liner material, Ajedium™ PEEK films, gives engineers the design freedom…

As electrification progresses, in-vehicle hardware and software architectures will evolve from distributed electronics to a “full car computer and zonal” model. We spoke with Patrick Leteinturier, Fellow Automotive Systems, Infineon Technologies, about these new architectures, new semiconductor materials, and the central role of “motion control”.

As the world moves towards an electrified future, the demand for permanent magnets is amplifying the already intense pressures on global supply chains. But in the sandplains of Western Australia, a small regional community called Eneabba is at the centre of what is set to become a globally significant and strategic hub for the downstream…

glulock® - A unique in-tool bonding technology for e-laminations in motor stacks Motor-cores have been build by mechanically interlocking individual motor laminations for decades. With materials in laminations for e-motor cores becoming thinner and thinner and increased efficiencies of electrified propulsion systems this process of mechanically interlocking the „stacks“ has become more and more difficult…

Perfect E-Shaft with Integrated Production Solution For the transmissions of electric vehicles to develop the desired high torque under all driving conditions, a very large gear ratio is needed, which requires high speeds. And to ensure sufficient momentum at all speeds and enable the driver to accelerate without shifting gears, the electric drive has to…

How far do powertrains extend? As electrification increases, you might say they go from plug to wheel. But as this year‘s discussions at the CTI Symposium in Novi showed, infrastructures and the availability of energy sources also need to be considered. The overarching factor is the need to reduce the CO2 footprint of future vehicles.…
