Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

Researchers at Harvard have demonstrated a metal-free organic–inorganic aqueous flow battery—a quinone–bromide flow battery (QBFB)—as an example of a class of energy storage materials that exploits the favorable chemical and electrochemical properties of a family of molecules known as quinones. —Huskinson et al.

The Role of Power Utilities in Turning EVs into a Grid Asset – Part 2

Driivz

The same approach can balance the flow of power between chargers at a workplace or destination, where cars are parked for relatively long time periods, to avoid grid overload during peak energy use. When wind and sun are plentiful, excess clean energy can be stored in the batteries of EVs that are parked and connected to smart chargers.

A Driver-Centric Approach Is Essential to Broad Vehicle-to-Grid (V2G) Adoption

Driivz

V2G returns the energy stored in EV batteries to the grid. In doing so, it promises to significantly advance the power system flexibility required to support charging the 250 million EVs projected to be on the road by 2030. EV owners don’t view their cars as devices that store energy for someone else’s use. Power aggregators?

The Essential Guide to EV Smart Charging and Smart Energy Management

Driivz

Smart EV charging uses intelligence to manage when and how an electric vehicle plugged into a smart charger will receive power for charging based on the cost of electricity, its availability, and the needs of the driver. At its most basic level, power flexibility gives users more options about whether and when to use energy.

Slow start for charge of the electric cars - Times Online

Tony Karrer Delicious EVdriven

In developing its E-Flex technology for the Chevrolet Volt (which will come toBritain as the Vauxhall Ampera) General Motors addressed this problem byadding a small petrol engine to start automatically and recharge thebatteries when they are running low and thereby extend the car’s range sothat it can reach a convenient power point.
