SAE International publishes new J2954 wireless charging standard

Green Car Congress

SAE International has published the first global standard that specifies, in a single document, both the electric vehicle and supply equipment (EVSE) ground-system requirements for wireless charging of electric vehicles (EV). The technology is a safe and efficient method for transferring power from the AC grid supply to the electric vehicle.

New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new battery design could help ease integration of renewable energy into the electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. Compared with a seasonal battery, this new design is especially adept at short- to medium-term grid energy storage over 12 to 24 hours.

SwRI forms joint industry program to investigate safety, longevity of grid-connected energy storage systems

Green Car Congress

Southwest Research Institute (SwRI) has launched a new Joint Industry Program (JIP) to investigate energy storage systems for the grid. Over the course of its life, a grid-connected battery must respond slowly or suddenly, depending on the grid demands. One of the central questions is how long it takes for a battery to degrade.

Ford, U Mich study finds greater greenhouse gas reductions for pickup truck electrification than for other light-duty vehicles

Green Car Congress

Cumulative greenhouse gas emissions versus vehicle mileage for (a) internal combustion engine and battery electric sedans, SUVs, and pickup trucks, and (b) hybrid electric and battery electric sedans, SUVs, and pickup trucks. The lower and higher limits of each range are results for base and premium models, respectively. .
