Just as the winner of a 2012 Chevy Volt in our Drive for Innovation contest was announced, the automaker revealed changes for the 2013 version of the car that goes on sale in August. (But I don't think winner Ted Yan will be feeling all that left out!)
On the technology side, the major upgrade is increasing battery capacity from 16kW to 16.5kW, along with as yet undisclosed changes to the battery chemistry. These revisions result in the EPA electric-only range of the car going from 35 miles to 38 miles. Consequently, full recharge time on 120V goes from 10 hours to 10.5 hours.
GM says, based on Volt owners' experience and data, that battery life is not as sensitive as it first supposed -- which could mean future versions will use more of the battery capacity with deeper discharging to improve range along with charging closer to full battery capacity.
The list price (including destination charges) stays at $39,995, not including a US government rebate of $7,500.
For a close-up look at GM's Chevy Volt, go to the Drive for Innovation site and follow the cross-country journey of EE Life editorial director, Brian Fuller.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
