CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

In a new study published in the journal Applied Energy , Carnegie Mellon University (CMU) researchers found that controlled charging of plug-in hybrid electric vehicles (PHEVs) reduces the costs of integrating the vehicles into an electricity system by 54–73% depending on the scenario.

Reference scenario impact indicator values by eight components and nine stressor sources. Components: WT = wind turbine; Fnd = foundation; EC = electrical connections, including substation; Inst = installation; IOo = input-output, other; Mnt = Maintenance, excluding replacement parts; RP = replacement parts; EOL = end-of-life.

Ford lowers fuel economy ratings for hybrids, plug-in hybrids, and Fiestas; goodwill payments to buyers coming

Green Car Congress

Ford Motor Company is lowering the fuel economy ratings for its 2013- and 2014-model year hybrid and plug-in hybrid vehicles, as well as most 2014-model year Fiestas. The MKZ hybrid, however, was hit with a 15.6% In some cases, the reduction was minor, on the order of 2-3%. This is our error. When we see an issue, we address it.

5 Big Ideas for High-Temperature Superconductors

Cars That Think

It refers to materials that superconduct above −195.79 °C, the boiling point of liquid nitrogen. But the materials could show up sooner in a wide array of practical applications, including wind power, energy storage, and nuclear magnetic-resonance machines. High temperature” isn’t room temperature.

EIA projects decline in transportation sector energy consumption through 2037 despite increase in VMT, followed by increase

Green Car Congress

For the Transportation sector, EIA projects that energy consumption will decline between 2019 and 2037 (in the Reference case) because increases in fuel economy more than offset growth in vehicle miles traveled (VMT). Light-duty vehicle miles traveled increases by 20% in the Reference case, growing from 2.9 trillion miles in 2018 to 3.5

EIA: light duty vehicle energy consumption to drop 25% by 2040; increased oil production, vehicle efficiency reduce US oil and liquid imports

Green Car Congress

LDV energy consumption declines in AEO2014 Reference case from 16.0 quadrillion Btu in 2040 in the AEO2013 Reference case. The rising fuel economy of LDVs more than offsets the modest growth in VMT, resulting in a 25% decline in LDV energy consumption decline between 2012 and 2040 in the AEO2014 Reference case.

Study: Combination of active and passive engine-off coasting delivers optimal fuel savings with 48V hybrid systems

Green Car Congress

However, the HELLA team noted, during passive engine-off coasting, the vehicle speed may slow down more than anticipated due to wind drag, rolling and mechanical frictions. CO 2 was reduced by 15% as compared to a reference micro-hybrid vehicle with only a stop/start function. B segment: 1200kg vehicle with 1.2l gasoline or 2.0l
