The evolution of cell interconnect technologies for battery pack manufacturing
Sponsored by Hesse GmbH By Sebastian Holtkämper, Product Manager, Hesse GmbH Looking back a decade ago on a tough worldwide EV market, hundreds of thousands of hybrid electrical vehicles (HEV), but only a few thousand battery vehicles (BEV) were yearly sold. Compared to the total car market, electric driving was a true niche experience at… Read more »
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 »
Zwickau VW plant to produce six electric models
The Volkswagen Group’s plant in Zwickau, Germany is undergoing a massive modernization process. When it’s done, the facility will be one of the biggest all-electric car factories in the world. The German automaker is investing some €1.2 billion to shift the plant’s production from three legacy models to six pure EVs from VW, Seat and… Read more »

HELLA develops two new battery systems for mild hybrids
Lighting technology and electronics company HELLA has developed two new battery systems for mild hybrids. The two systems, the Dual Voltage Battery Management System and PowerPack 48 Volt, allow for savings of five to six grams of CO2 per kilometer, according to the company. Designed for compact and mid-range vehicles, the Dual Voltage Battery Management System… Read more »
SiC vs GaN semiconductors for EV power converters: Tech Opinion
Just as engineers are starting to get used to the advantages (and quirks) of silicon carbide (SiC ) devices, another semiconductor material joins the fray: gallium nitride, or GaN. Though there are some superficial similarities between these two materials, and even some overlap in their areas of best use, it is my opinion that only… Read more »
BorgWarner unveils new onboard battery charger
Automotive parts supplier BorgWarner has released a silicon carbide onboard battery charger that is compatible with 400, 600 and 800 V systems. It accepts AC inputs with 7.4 kW, 11 kW, and 22 kW power ratings. Optional DC-to-DC converter rating integration from 2.3 kW to 3.6 kW is available. “Our technical center is dedicated to… 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 »
