You can tell it the color and the right color shows up.Herm said:Scott, does that app keep track of the color of your Volt?

Almost 62% electric, nice.scottf200 said:Some cool numbers I thought today (30-Nov-2012) via: http://www.chevrolet.com/volt-electric-car.html
Martin Tesar said:I decided to purchase the Volt – as I fully appreciate both its technology, what it does achieve and a lifelong dream from a Childhood reading a futuristic book from our State Electricity Commission that the future would be electric. And that included an electric car – which at the time left me wonder how?
When I heard they were about to take pre-orders back in June 2012 I jumped at the chance. At first I was a little shocked that I couldn’t customise the car like in NA, only the exterior colour. I rang round got the best price and place my deposit with an established dealer.
Luckily I was very patient – until I knew the car was in port Early November, then I started to call Holden and the dealer as to why the wait? In the background I wasn’t too stressed as I was still finished the garage renovation and that was taking way longer than expected.
Not a problem. If they are driving it, the gas generator will always keep a minimum (safe) charge. The Volt uses a range of about 23-87% SOC (or thereabouts). The 23% minimum is unlikely to drop significantly if not driven, even in three weeks. And if driven it will maintain that level, or slightly higher.camasleaf said:My employer bought 2 Volts, but has no charging capabilities. They are working on getting EVSE installed, but they are not sure when is going to happen. The cars are running on gas only, with the reasoning that "it still gets 35 mpg". My question is how long can the battery stay at the lower level without any damage? I believe it has been over 3 weeks already.
Yep, if anything the low SOC and minimal cycling will extend calendar life of the battery pack.LEAFer said:Not a problem.

To keep its cool, and warmth, GM engineers opted for a liquid-cooled pack rather than air cooling for durability, thermal stability, and packaging benefits. Li-ion automotive batteries must endure very high dynamics. Momentary peak loads, such as created during brake-energy regeneration and acceleration, generate powerful electrical currents. The currents create internal resistance, which causes significant warming of the cells.
Temperature extremes can diminish a battery’s efficiency and rapidly accelerate battery aging, noted Frank Weber, Volt’s enthusiastic and laser-focused Global Chief Engineer who departed the program last year for Opel.
“For example, the delta between 70°F (21°C) and 90°F (32°C) can be critical to battery life,” he asserted. The battery is designed to work while plugged in, at temperatures from -13°F (-25°C) to +122°F (+50°C). The permitted temperature gradient within a battery cell, and from cell to cell, is 5 to 10 K.
A 50:50 glycol mixture is actively circulated through 144 metal “fins” between each of the Volt’s 288 cells. The fins are 1-mm-thick (0.04-in) stamped aluminum plates that conduct heat. The Volt’s pack has five thermal management circuits to handle the multiple subsystems. The system uses multiple electric coolant pumps (12- and 50-W) supplied by Buehler Motor of Germany. The pumps feature brushless dc motors and integrated electronics, and are designed to run extremely quietly, explained Robert Riedford, President of Buehler Motor Inc.
In cold weather, the battery is preheated during charging. Inputs from 16 temperature sensors are sent to a heating coil that warms the coolant, regulating individual cells’ temperature, said Bill Wallace, GM’s Director of Global Battery Systems.
GM engineers worked with heat-transfer systems expert Behr America to develop Volt’s front-end cooling module (FECM) as well as to introduce the industry’s first use of “chiller” technology in a production electrified vehicle. (See sidebar, page 33.)
Volt’s battery management system runs more than 500 diagnostics at 10 times per second, continuously monitoring the battery in real time. GM engineers said 85% of the diagnostics ensure the pack is operating safely, while the remaining 15% track battery performance and life.
Weatherman said:When I test-drove a Volt a few months ago, I was surprised to see no battery temperature gauge on the dash display. Has any Volt owner been able to read the temperature of the battery to see how well the TMS is performing? I’d be curious as to how well the insulation keeps temperatures under control if you happen to work some place where you have to park your car out in the sun all day and can’t plug it in.
I'm sure it's been discussed before, but there are several variations on battery temp available on DashDAQ - min cell temp, max cell temp, average temp, and I think one or two more. Watching average the last few weeks, it hasn't done much. In the 90-100 degree heat last week, it was 77-81. These last couple days with 50 degree mornings, it was 77...
Some Chevrolet Volt Dealers Back Out Of Program Due To High Cost Of Tools
General Motors sent all of their Volt-certified dealers a bill for $5,100 worth of specialized tooling. Some of Chevrolet’s 2,614 Voltec dealers, estimated to be as high as 40, said they would rather not sell the car then.
Last year, according to GM spokeswoman Michelle Malcho, dealers spend between $1,800 and $2,800 on specialized equipment for the Volt.
However, beginning on January 1st, 2013, Chevrolet wants local technicians to have the ability to remove and ship segments of the Volt’s over 400lb battery in order to save costs. Previously, the entire pack was removed and returned for service.
In order to be able to ‘divide and conquer’ the pack, dealerships need a $4,735 battery depowering tool to drain the battery before removing sections...
You are certain attempting to spin this with your 'frequency soon' comment ... as usual (looking at your consistent post in this thread). You can search gm-volt.com but it seems pretty rare. Glad they are planning ahead and have the confidence they can just replace part of the pack as needed. Obviously from the past few post above they have carefully and responsibly planned the battery management.edatoakrun said:I guess GM expects to require battery servicing at some significant level of frequency soon.
Anyone know how frequently Volt's have had their "entire pack...removed and returned for service" so far?

40 dealers out of how many? let them not sell it. anyone stupid enough to not see the writing on the wall deserves to get what they ask for. imm, $5100 is a bargain. in fact that price is too low to believe. that kind of specialized equipment simply does not come cheap
bet those very same dealers would not hesitate a second to spend $50,000 on fixing up the showroom. dont get me wrong, a nice showroom does help but without the product you cant sell what you dont have.
this battery thing? its just the very very very beginning. the sooner you get on board the less catch up you WILL HAVE to do
