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 »

Duke Energy pilot supports charging infrastructure in South Carolina

Duke Energy has proposed a three-year, $10.4-million pilot initiative to support the installation of charging stations in South Carolina. The pilot is comprised of four programs with the overarching goal of understanding the impact increased EV adoption will have on the electrical grid: Residential EV Charging Program – Provides rebates for up to 400 residential… Read more »

SAE releases new J3068 specification for charging of medium- and heavy-duty EVs

SAE International has published its recommended practice for plug-in charging of heavy-duty EVs. The new J3068 standard allows vehicles to fully utilize three-phase AC power. Presenting a symmetric three-phase load enhances grid stability, especially at high power levels. SAE J3068 standardizes an AC three-phase-capable charging coupler and digital control protocols, offering sufficient power and reliability… Read more »

New study finds V2G discharging harmful to EV batteries

Vehicle-to-grid (V2G) technology is seen as a potentially valuable resource for balancing electrical grids and facilitating the use of renewable energy. However, a new study by a team at the University of Hawaii suggests that the additional cycling to discharge vehicle batteries to the grid is detrimental to battery performance. In “Durability and reliability of… Read more »

Groupe PSA and partners launch GridMotion smart charging project

Groupe PSA and several partners have launched a new project to evaluate smart charging technology. The idea is to reduce an EV driver’s electricity bill by shifting charging times to periods of lower electricity prices. Further savings could be achieved by providing grid balancing services through a Vehicle to Grid (V2G) system. The two-year GridMotion… Read more »
