Continental showcases full hybrid with 48-volt drive system

Continental has introduced a 30 kW, 48-volt high-power drive system for full hybrid vehicles, which it says is cheaper than the high-voltage systems used up to now. Until now, manufacturers have typically used 48-volt systems in “mild hybrid” vehicles, in which the electric motor doesn’t drive the vehicle directly, but only assists the ICE. Full… Read more »

Power Integrations’ new gate-driver system enables paralleling of up to four SiC power modules

Power Integrations, a manufacturer of gate-driver technology for medium- and high-voltage inverter applications, has introduced the SCALE-iFlex gate-driver system for IGBT, hybrid, and silicon-carbide (SiC) MOSFET power modules with blocking voltages from 1.7 to 4.5 kV. The system consists of a central Isolated Master Control (IMC) and one to four Module-Adapted Gate Drivers (MAGs). The… Read more »

Survey finds biggest concern in EV battery industry is time to market

Voltaiq, a battery software platform company, has released an industry survey, Preparing for The Electrification Tsunami, that examined many of the challenges battery manufacturers, suppliers, and integrators currently face. Conducted in Q1 2019, the survey polled battery cell producers, battery pack and component developers, academic and national labs, and companies involved in transportation, consumer electronics,… Read more »

M&I Materials’ new dielectric fluids for battery and charger immersion cooling

UK-based M&I Materials has developed a new range of biodegradable dielectric fluids, MIVOLT, to provide immersion cooling for EV batteries and charging points. As non-conductive fluids, MIVOLT fluids can come into direct contact with electronic components, which M&I says is a more effective method of heat removal and a lighter-weight option than designs that rely… Read more »

Wildcat Discovery Technologies receives second patent for silicon anode electrolytes

Wildcat Discovery Technologies, a company that uses high-throughput methods to develop next-generation battery materials, has received a second patent on its development of electrolytes for silicon anode batteries. Wildcat’s first patent for this work was awarded in late 2018 and covered the use of sulfolane-based electrolytes. This new patent covers acrylate-based additives which can be… Read more »
