Nanoflowcell flow tech cars nearing production

The first time we heard about Nanoflowcell, it was at the 2014 Geneva Motor Show, where it revealed the Quant E. The startup followed that appearance up with a double debut at the 2015 Geneva Motor Show, showing the Quant F and smaller, simpler Quantino. Now its flow cell-powered cars are nearly ready for production, and the latest versions will be featured at this year's Geneva event.

California to get utility-owned EV charging stations with dynamic pricing

The California Public Utilities Commission has approved a pilot program that will see public utility San Diego Gas & Electric install and operate 3,500 new charging stations for electric vehicles. Charges for plugging in to charge an electric vehicle will vary according to time of day in a scheme meant to encourage off-peak charging when renewable power sources are more plentiful.

Lithium-oxygen breakthrough clears the air for boosted batteries

Boasting an energy density similar to that of gasoline, lithium-air (or lithium-oxygen) batteries may one day prove the panacea for the range-anxiety associated with electric vehicles. But first there are a number of challenges that need to be overcome, one of which is the unwanted buildup of lithium peroxide on the electrode which hampers this type of battery's performance. Scientists have now figured out a way that this mess might be avoided – an advance they say could lead to batteries with five times the energy density of those currently available.

Lithium-ion battery warms itself in cold environments to maintain performance

Extreme temperatures can seriously compromise the performance of lithium batteries. We've seen a number of developments promising to reduce the risk of them overheating and catching fire, but at the other end of the scale, freezing temperatures aren't too friendly either, often leading to substantial power loss. In an advance that could have ramifications for everything from electric vehicles to space exploration, researchers have built a lithium battery that warms itself up to battle the winter chill.
