ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

Because the use of natural gas for transportation requires compressing, liquefying, or conversion, it is important to determine the best use of natural gas as a transportation fuel. The WTW analysis focused solely on the fuel-motive power cycle, disregarding the vehicle cycle—i.e., —Curran et al. Curran, Robert M.

Lux: future use of wide bandgap materials in power electronics will reduce EV cost

Green Car Congress

In electronic devices, WBG semiconductors can eliminate up to 90% of the power losses that currently occur during AC-to-DC and DC-to-AC electricity conversion, and they can handle voltages more than 10 times higher than Si-based devices, greatly enhancing performance in high-power applications.

Forecast: Lithium Ion Batteries for Electric Vehicles to Approach $8 Billion in Sales by 2015

Green Car Congress

PHEV/EV Models 2010-2012 by Battery Chemistry. Battery chemistries that prioritize energy capacity over power density can equally satisfy both the plug-in hybrid electric vehicle (PHEV) and the EV battery segments, enabling vendors to offer products to multiple vendors for multiple models.

Best speakers ever

Electric Auto Association

When Straubel—also known for his 1984 Porsche 944 EV conversion—left Tesla, he founded Redwood Materials , a leading lithium battery recycling company in Carson City, Nevada. He had all these charts and graphs showing the power going into the motor. That was quite a conversion.” After that, the word spread fast.”

Soot and Spin: Two Plug-in Paradoxes

Plugs and Cars

Paradox 1 - Soot: There's an apparent emissions paradox with plug-in hybrids (PHEV): Driving longer distances on battery power means more cold starts as the internal combustion engine (ICE) stops and starts up again after the batteries deplete. They could make PHEVs and EVs today, but they don't want to.

The driver can program times for charging as well as preheating or cooling and adapt them to his or her requirements, such as departure time, so as to save resources and costs. This is made possible by the second-generation modular infotainment platform, which uses the high computing power of the Tegra 30 chip from Audi’s partner NVIDIA.

Naysayer Alert – the hydrogen red herring

My Electric Car

Nonetheless, hydrogen fuel cell cars are, like pure battery powered cars, classed as Zero Emission Vehicles (ZEV). If taken from such sources, hydrogen is a fossil fuel, and is not a renewable resource. The only by products are water and a fair degree of heat, the latter indicating a degree of inefficiency and wasted energy.
