Argonne study finds BEVs can have lowest scheduled maintenance costs, but highest cost of driving

Green Car Congress

The study considers five different powertrains (internal combustion engine, hybrid-electric, plug-in hybrid-electric, fuel-cell-electric, and battery-electric) and 12 cost components (purchase cost, depreciation, financing, fuel, insurance, maintenance, repair, taxes, registration fees, tolls and parking, payload capacity and labor).

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

Smaller Ioxus cells offer a power density of 22-28 kW/kg, and larger cells offer densities of 12-15 kW/kg, said Chad Hall, COO of Ioxus. both electrodes are carbon, as opposed to the hybrid (asymmetric) ultracapacitors in which in one of the electrodes is carbon and the other electrode utilizes a different material.
