The term DC link has traditionally referred to the junction between two power conversion stages where an energy storage element (almost always a capacitor) acts as a buffer for each. A classic example is the capacitor placed between the rectifier and the voltage source inverter in a mains-supplied variable frequency drive (see Fig. 1). This… Read more »

Scania introduces range of electric trucks
Scania, a major Swedish manufacturer of commercial vehicles, has announced a pair of new plug-in trucks: a plug-in hybrid and a fully electric model. Both versions are offered with L- and P-series cabs, and can be configured for general cargo, temperature-controlled transport, or for specialty applications such as hooklifts, tippers, concrete mixers, refuse collectors and… Read more »
Teardown expert Sandy Munro compares 10 leading EV motors in new video
Auto manufacturing expert Sandy Munro knows what makes cars tick. For years, he and his company have performed teardowns, taking new cars apart and analyzing every little bracket and screw—what it’s made of, who made it, and how much it cost. This week at the Charged Virtual Conference on EV Engineering, Sandy compared an assortment… Read more »
The technical challenges of bidirectional chargers
For years, we’ve been hearing about an EV technology that promises to be a game-changer: Vehicle-to-Grid (V2G) bidirectional charging. My recent work with one V2G charger developer, Fermata Energy, has convinced me that V2G has found its proverbial killer app: load peak shaving for commercial/industrial energy customers. This article is going to concentrate on the… Read more »
Tampa, Florida secures federal grant to deploy four electric buses
The Hillsborough Area Regional Transit Authority (HART), which serves the Tampa, Florida, metropolitan area, has secured a $2.7-million federal grant to buy four electric buses, which are expected to be in service in two years. The federal grant will cover half the total project cost, which also includes underground wiring and charging stations. HART and… Read more »
Next EV hotspot: Alabama?
You may not think of Alabama as a center of the auto industry, but in fact, Mercedes-Benz opened an assembly plant in Tuscaloosa County back in 1993, and today Hyundai, Honda, Toyota and Mazda, as well as several Tier 1 and Tier 2 suppliers, have operations in the Yellowhammer State. You may also think a… Read more »
In-Charge Energy is preparing for the coming tsunami of commercial electric trucks
Widespread adoption of electric commercial vehicles has seemed to be just around the corner for several years now. This has been a puzzling and frustrating situation for EV advocates (and even more so for electric truck builders), because the economic case for electrification is strong. Several industry experts have told Charged that the slow progress… Read more »
