Pre-Switch promises to add 5-12% more EV range by eliminating switching losses
How would you like it if your EV could go ten percent farther with the same size battery? You’d love it, of course, and so would every EV manufacturer out there. Range is one of the most important parameters in the EV industry, as many potential EV drivers are apprehensive about lower range ratings. Manufacturers… Read more »
No, Workhorse hasn’t yet secured funding to buy GM’s Lordstown plant, but the deal is moving forward
For some time, Charged has followed the story of Workhorse Group, a Cincinnati-based company that has built a prototype electric pickup, has sold electric trucks to UPS and FedEx, and is in the running for a major contract to supply delivery trucks to the US Postal Service. Along with other observers of the EV scene,… Read more »
BMW’s electric Mini Cooper SE: redeemer or regression?
BMW can’t seem to make up its mind about electrification (the same could be said about most of the legacy automakers). In 2013 it released the i3, which was a giant stride forward at the time. The once-revolutionary city car continues to sell in respectable numbers in some European markets, but BMW never followed up… Read more »

A closer look at the losses in power semiconductors
A previous article examined loss mechanisms in traction motors, which tend to be the single biggest source of losses in a modern EV drivetrain. This time, the focus is on the various power semiconductors, as they are the next biggest source of losses. Also covered in brief are ways to mitigate these losses and design… Read more »
Freudenberg develops lightweight plastic housing to seal against electromagnetic radiation
Researchers at Freudenberg are developing a plastic housing material for EV electronics as an alternative to heavier and more costly aluminum. To protect against electromagnetic waves that can disrupt signal flow in microprocessors and transmitter-receiver systems, EV makers typically encase electrical components in conductive metal housings, usually aluminum. Freudenberg says the additional weight of the… Read more »
