Google and IEEE launch $1M challenge for downsized inverters

Green Car Congress

Google and the IEEE have launched the Littlebox Challenge—an open competition to design and build a small kW-scale inverter with the highest power density (of at least 50 W/in 3 , or 3.05 kW/L) in an enclosure of less than 40 in 3 in volume (0.66L). USABC Electrical and Electronics Technical Team Roadmap (June 2013).

Penn State, EC Power use internal thermal modulation to enable stable fast charging

Green Car Congress

Further, we build a digital twin of such a battery pack to assess its cooling and safety and demonstrate that thermally modulated 4C charging only requires air convection. 1 battery to 75% (or 70%) state of charge in 12 (or 11) minutes for more than 900 (or 2,000) cycles.

Study Assesses Product Attribute Trade-offs and Technological Progress; Meeting Proposed Obama Fuel Economy Standards Will Require Downsizing and Change in Fleet Mix

Green Car Congress

Honda, Toyota and Nissan rank higher than US manufacturers for passenger cars (Nissan and GMC are effectively equal), but the three Japanese manufacturers trail GMC when building light duty trucks, while only Honda surpasses Ford. The estimates are ranked by the firms’ light truck efficiency; the rankings change considerably. Knittel, 2009.

Scaleo chip introduces Advanced Motor Events Control (AMEC) technology for internal combustion engine and electric motor control

Green Car Congress

Carmakers are developing a wide variety of new powertrain systems, from downsized thermal engine, to hybrid systems to full electric motorization. AMEC simplifies ECU design and saves cost, banning useless external logic or component to build a complete function or match response timing.

Westport and GTI awarded $900,000 to advance natural gas combustion technology; ESI with high frequency corona discharge ignition

Green Car Congress

The technology enables a “downsized” natural gas solution that is cost-competitive while providing similar levels of power, torque, and fuel economy to a larger diesel engine. Westport will contribute approximately $250,000 in additional funds for a total of $1.15

ECONAMIQ: Flexible over-expansion with cylinder deactivation can reduce ICE fuel consumption by up to 20%

Green Car Congress

The new ECONAMIQ technology builds on existing concepts such as cylinder deactivation and variable valve timing with a unique patented combination of routing gasses for increased system efficiency. The residual pressure of at the end of the power stroke is used in an extra low-pressure stroke of the non-burning cylinders.

A123: Increasing 48V battery power up to ~25 kW enables advanced mild hybrid capabilities with greater fuel savings

Green Car Congress

Improving battery power to such as level would further enable hybridization to near-HEV levels as well as engine downsizing, thereby enabling fuel economy improvements beyond the current 10-15% MHEV limit. Additionally, advanced features such as electric low-speed drive, park-assist, electric-turbo, and others may utilize the 48V system.
