Smart charging specialist Wallbox acquires charging app provider Electromaps

Wallbox, a Barcelona-based manufacturer of smart charging solutions, has announced the acquisition of Electromaps, a digital platform for locating and accessing charging points. The Electromaps app, which allows users to access and pay for charging directly from their mobile phones, features a database of over 120,000 recharging points in 120 countries, and has some 100,000… 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 »

Protection For Electric Vehicle Charging Infrastructure

  This presentation will discuss fault analysis, protection and switch-disconnection in Electric Vehicle Charging Infrastructure from transformer LV side, passing through the AC/DC front-end converter to the DC fast-chargers. This session will analyze the short-circuit and ground fault transient and steady-state condition considering all the contributions coming from the AC grid and the all the… 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 »

ORNL demonstrates bi-directional wireless charging on UPS delivery van

Researchers at the DOE’s Oak Ridge National Laboratory (ORNL) recently demonstrated a 20-kilowatt bi-directional wireless charging system installed on a UPS medium-duty, plug-in hybrid electric delivery truck. In the demo, the system transferred power at more than 92% efficiency between the truck and a charging pad across an 11-inch air gap, using two electromagnetic coupling… Read more »

Fermata receives UL certification for vehicle-to-grid EV charging system

Underwriters Laboratories (UL) has announced that Fermata Energy’s bidirectional EV charging system is the first in the world to be certified to a new North American safety standard, UL 9741. The standard covers bidirectional equipment that charges EVs from an electric power system (EPS) and also allows the vehicle to export power to an EPS,… Read more »

Wallbox’s bidirectional DC home charger turns heads at CES

Bidirectional charging encompasses several applications that can be collectively referred to as V2x (vehicle-to-grid, vehicle-to-home, maybe someday vehicle-to-brain). It’s expected to play an important role in tomorrow’s electrified, connected transportation ecosystem, but to date it exists only in pilots, most of them involving commercial fleets. So the new Quasar bidirectional EV charger from Barcelona-based Wallbox,… Read more »

SAE updates J2954 wireless charging standards for EVs up to 11 kW

SAE International has published a second version of Recommended Practice (RP) SAE J2954, its standard for wireless power transfer (WPT) for EVs of up to 11 kW power levels. The RP establishes specifications for interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for wireless charging of light-duty electric and plug-in EVs. SAE is seeking… Read more »
