Report: VW invests in novel energy storage company QuantumScape and its solid-state “All Electron Battery”

Green Car Congress

Volkswagen executives have been hinting for awhile now about taking a different approach to high-energy-density electrical storage for long-range electric vehicles than the more “conventional” next-generation Li-ion or Li-metal battery pathways. conventional capacitors). roughly the same as the target.

ORNL demos 20 kW bi-directional wireless charging on UPS PHEV truck; 11" air gap, >92% efficiency

Green Car Congress

Researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) in late February demonstrated a 20-kilowatt bi-directional wireless charging system installed on a UPS medium-duty, plug-in hybrid electric delivery truck. UPS appreciates the Department of Energy’s support on this effort.

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.

Two studies exploring battery costs for hybrids and plug-ins: LEESS, PHEV20, and PHEV40

Green Car Congress

For PHEV20 batteries, TIAX found significant overlap in battery costs among five cathode classes, with wider variation within each chemistry based on the electrode design than between chemistries. kWh of usable energy storage, satisfying drive cycle requirements over the 20-mile urban drive cycle.

EKODA consortium exploring direct reuse or repurposing of batteries, gearboxes

Green Car Congress

It records the battery type, model, serial number and power class (in kilowatts) and compares this information with an internal database. If the energy storage system is older, it would be possible to use it in a smaller agricultural machine. Next, the battery cover is removed through a semi-automated process.

New Electrostatic Nanocapacitors Offer High Power and High Energy Density

Green Car Congress

Batteries, particularly lithium-ion, store large amounts of energy but have more difficulty with high power or fast recharge. Electrostatic capacitors are characterized by high power but energy storage is limited because only surface charge is used. Gary Rubloff.
