DOE seeking comment on draft $50M solicitation for new projects over 11 areas of interest to improve vehicle performance and decrease fuel consumption

Green Car Congress

A prototype demonstration part shall be produced which reproduces, to the maximum extent practicable, the expected stresses, clearance, dimensional stability, and fatigue challenges of next generation high efficiency internal combustion engine rotating components. In this AOI, solutions should be capable of being commercially manufactured.

Are electric vehicles safer than combustion engine vehicles?

Electric Vehicles India

Yesterday also we get to hear a similar incident from Okinawa where the electric scooter had been parked in a garage and being recharged in the night when a blast had occurred. Firstly if we look at the conventional vehicles which use internal combustion engines, it is challenging to replace an ICE vehicle with an electric one.

TU Graz team uses monocrystalline Si as Li-ion anode; integrated micro batteries for on-board sensors

Green Car Congress

Electrochemists at TU Graz have used single crystalline acceptor-doped Si—as ubiquitously used in the semiconductor industry—as anode material for rechargeable Li-ion batteries. This increase amounts up to 300% if we refer to amorphous silicon (a-Si) and complete electrochemical lithiation (0 mV vs Li/Li + ).

A closer look at minimizing AC charging losses: From the breaker to EV (Part 1)

Charged EVs

In this article we’ll be taking a closer look at ways to minimize charging losses that are under the control of either the manufacturer or the owner of the EV (in other words, excluding things like changing the electrical generation source from coal to nuclear or solar, as helpful as that would be).

Why Warren Buffett is investing in electric car company BYD - Apr. 13, 2009

Tony Karrer Delicious EVdriven

MidAmericans David Sokol, BYDs Wang, and company advisor Li Lu flew with Sokol from Detroit to Omaha so that Wang could meet Buffett in person. By about 2000, BYD had become one of the worlds largest manufacturers of cellphone batteries. The E6 will hit the Chinese market later this year. "The GPS isnt working," she says.
