Using bidirectional programmable DC power supplies for battery testing
Sponsored by EA Elektro-Automatik In today’s fast-paced world the need to create quicker, more mobile mechanical devices is steadily increasing. One primary method for doing this is to replace traditional gas-powered or plugged-in devices with battery power. Batteries have become smaller and increasingly efficient as a result. In order to keep up with the rate… Read more »

Fleet management specialist ViriCiti has begun rolling out a major implementation of its Smart Charging service for Qbuzz, a public transport operator in the Netherlands that runs a fleet of 782 vehicles. Qbuzz will use ViriCiti’s Smart Charging solution to manage a total of 163 chargers (both plug-in and pantograph) from Heliox and ABB, which… Read more »
3 factors that impact gap filler reworkability in EV battery packs
Sponsored by Parker LORD The design of electric vehicle battery packs may vary among manufacturers but commonly, the battery is attached to its cooling plate not only with fasteners but also thermally conductive polymeric materials called gap fillers. Gap fillers can outperform thermal pads in this application to achieve lower thermal impedance, as the gap… Read more »
ZF orders another bdtronic trickle impregnation machine for EV motor production
bdtronic, a German mechanical engineering company and process specialist, will provide ZF Friedrichshafen with another trickle impregnation machine for electric motor production. ZF is already using bdtronic systems at several locations worldwide, and is now ordering the next machine for the trickle impregnation of hairpin stators. The stators will be used for front- and rear-wheel… Read more »
DOE to fund EV charging cybersecurity in Michigan
The DOE has announced more than $7 million in funding for a Michigan-based cybersecurity company, Dream Team (DTLLC), to develop an infrastructure that protects the electric grid from cyber-attacks on EVs and EV charging systems. Once the electric roadway and vehicle-to-grid (V2G) technology has been developed, it will be tested at the American Center for… Read more »
