UPS-led SEUL consortium switches on smart-grid fleet charging solution in London; maxing out on EVs without expensive grid upgrades

Green Car Congress

A UPS-led consortium has deployed new smart-grid charging technology in London that overcomes the challenge of simultaneously recharging an entire fleet of electric vehicles (EVs) without the need for the expensive upgrade to the power supply grid. UPS thinks this is a world first, right in the heart of a mega-city.

NTSB Chair questions safety impact of heavy EVs

Green Car Congress

During a keynote speech to the Transportation Research Board annual meeting Wednesday, National Transportation Safety Board (NTSB) Chair Jennifer Homendy questioned the safety impact of electric vehicles. Electrifying vehicles adds yet more weight. Heavier vehicles also generate more particulate pollution from tyre wear.

BNEF ups forecast for global investment in stationary energy storage, sees majority of capacity likely to be grid-scale

Green Car Congress

BNEF projects that it will be made possible by further sharp declines in the cost of lithium-ion batteries, on top of an 85% reduction in the 2010-18 period. The report goes on to model the impact of this on a global electricity system increasingly penetrated by low-cost wind and solar.
