Comparing liquid-dispensed gap fillers and thermal pads in battery packs: WEBINAR

Heat generated in high-density automotive battery packs is often managed by connecting battery cells and/or modules to a heat sink via a thermal interface material (TIM). The TIMs promote heat conduction by displacing any air that resides within the large gaps and microscopic rough surfaces that exist between the substrates to be bridged. In practice, battery… Read more »

Ecovolta to build automated 200 MWh battery assembly plant in Switzerland

Swiss battery system and production specialist ecovolta (don’t kill us yet folks, the lowercase isn’t a typo) will build a 200 MWh battery pack assembly plant this September in the Swiss canton of Schwyz. The plant will use fully-automated processes to produce both prismatic and cylindrical batteries. The battery packs will have voltage levels ranging… Read more »

ZapGo’s Carbon-Ion tech combines power density of supercapacitors and energy density of batteries

Williams Advanced Engineering has selected ZapGo, a spinout of Oxford University, to join a consortium working to develop next-generation battery systems for EVs (part of the UK government’s Faraday Battery Challenge). ZapGo’s Carbon-Ion technology, based on carbon nanomaterials including graphene, is intended to combine the power density of supercapacitors and the energy density of rechargeable… Read more »

New thermoelectric superlattice doubles rate at which waste heat is converted to electricity

Researchers from Hokkaido University and colleagues in Japan and Taiwan have improved the ability to transform wasted heat into usable electricity by narrowing the space through which spread electrons move, according to a new study published in Nature Communications. Currently, more than 60 percent of the energy produced by fossil fuels is lost as waste… Read more »

ZF’s Axle Hybrid concept electrifies its AMT to improve shifting performance

German automotive supplier ZF has unveiled a new Axle Hybrid concept which uses an electrified Automated Manual Transmission (eAMT). This system combines ZF’s traditional electric axle drive system (eVD) with its automated manual transmission (AMT). The eAMT eliminates tractive force interruption and features AWD capabilities. “With eAMT, ZF has developed a fully-fledged plug-in hybrid drive for front-transverse vehicles,”… Read more »
