Harvey Gulf orders Wärtsilä energy storage for four LNG-powered supply vessels
Wärtsilä, a provider of marine industry LNG solutions and services, will supply its Energy Storage System (ESS) to Louisiana-based Harvey Gulf, which will retrofit the system to four Harvey Energy-class LNG-fueled Platform Supply Vessels (PSVs). A fifth vessel in this class was previously fitted with a Wärtsilä ESS. When the upgrade project is completed, all… Read more »
A closer look at the DC Link
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 »
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 »

Lightning Systems triples size of Colorado EV facility
Commercial EV supplier Lightning Systems is tripling the size of its facility in Loveland, Colorado. Lightning moved its headquarters, manufacturing and R&D into the former Hewlett-Packard/Agilent campus in southwest Loveland three years ago. The company recently took over the entire building, expanding its square footage from 45,000 to 142,000. “Our mission is to provide commercial… Read more »
The sun-to-car connection: SolarEdge provides the missing link from solar panels to EV charging
Q&A with SolarEdge Founder and VP of Marketing and Product Strategy Lior Handelsman An EV is a fine thing on its own—but it becomes truly transformative as part of a local system that also includes solar panels, battery storage and smart charging. SolarEdge Technologies provides hardware and software to bring these elements together, including solar… Read more »
Webinar: Designing silicon carbide solutions for EV fast charging
EV fast chargers bypass the vehicle’s on-board chargers (OBCs) for rapid direct battery charging. This allows batteries to be charged in just 30 minutes versus 4+ hours from OBCs. But the demands of these systems are significant. Design goals for fast chargers call for highly efficient power electronics and very high power density that’s possible… Read more »
