JERA and Toyota deploy first large capacity Sweep Energy Storage System with second-life batteries

Green Car Congress

JERA, the largest power generation company in Japan, responsible for about 30% of Japan’s electricity, and Toyota Motor have built and deployed the first large-capacity “Sweep Energy Storage System”. The project plans to operate grid storage batteries for recharge and discharge operations, connected to the Chubu Electric Power Grid Co.,

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

The analysis indicated that electrified fleets had 40-45% lower greenhouse gas costs per trip compared to the gasoline-powered version. In the simulations, battery-powered vehicles, particularly the 40 kWh ones, needed more frequent and longer trips without passengers to get to recharging stations. 2c07030

Hawaii study finds vehicle-to-grid discharge detrimental to EV batteries

Green Car Congress

Results of a study by a team at the Hawaii Natural Energy Institute, SOEST, University of Hawaii at Manoa, suggest that the additional cycling to discharge vehicle batteries to the power grid in a vehicle-to-grid (V2G) scenario, even at constant power, is detrimental to EV battery cell performance. 2017.05.015.

Berkeley study finds self-driving electric taxi fleets in Manhattan would deliver significant cost and environmental benefits

Green Car Congress

We found plenty of times during the day when a portion of taxis could slip off to recharge, even if just for a few minutes. They further estimated that such an SAEV fleet drawing power from the current NYC power grid would reduce GHG emissions by 73% and energy consumption by 58% compared to an automated fleet of ICEVs.

AeroVironment licenses PNNL EV smart charger controller technology

Green Car Congress

Under normal conditions, this stabilizing technology will be particularly important as the power grid is expected to rely more and more on variable renewable resources such as wind and solar technologies. If a million owners plug in their vehicles to recharge after work, it could cause a major strain on the grid.
