800V Electric Vehicles Charge into Mainstream with SiC Power Electronics 

The demand for electric vehicle power electronics will increase dramatically in the next ten years, primarily driven by rapid growth in the battery EV car market, where market analyst IDTechEx of Cambridge, UK, predicts a 15% CAGR globally over the next decade. Currently, the weighted-average battery capacity of BEV cars is increasing in all regions, piling pressure on battery supply chains, and creating uncertainty. The result is that drive cycle efficiency must come to the forefront of powertrain design, meaning the time has come for high voltage wide bandgap power electronics. […]

Tech Tips: Removing the Bottleneck in Welding Electrical Conductors for EVs 

The need to increase the rate of joining electrically conducting components has become critically important in the electric vehicle sector as it is emerging to be the bottleneck of manufacturing, according to Alex O’Farrell, development engineer with Cambridge Vacuum Engineering. As a maker of welding machinery, the UK-based company works close to the subject. In a recent presentation prepared for the 75th International Institute of Welding Annual Assembly & Conference in Tokyo, O’Farrell made his case for electron beam welding technology, highlighted here.  […]
