4:01	Britta Gross - Hi everyone. Mark Duvall and I are here at the Business of Plugging In Conference in Detroit. Great forum so far.

4:01	Mark Duvall - I agree with Britta, great conference so far. Ready to answer your questions.

4:02	[Comment From Bernard Simon ] What recharging infrastructure can Chevy Volt buyers realistically expect when they drive a car out of the dealership in early 2011? Thanks.

4:03	Britta Gross - The good news is the only thing we really have to have in place is a solution for home charging. As Jon Lauckner said this morning, the Volt comes with a 120-V charger and if you can find a normal outlet, you can charge the Volt.

4:04	[Comment From Philipp Andres ] I am wondering what actual value V2G has for car owners if the battery is like that for the Chevy Volt with a 50 mile range

4:04

Mark Duvall - V2G is definitely something of a future technology. Many believe that it has a pretty strong business case behind it, as long as there is not too much impact on battery life and the vehicle would always be available when the owner wanted to drive it---as this is primary reason you buy a plug-in vehicle.

4:05	[Comment From John Brown ] I saw somewhere that GM would 'inspect' (or arrange inspection) of home charging infrastructure?

4:08

Britta Gross - There are going to be several solutions. Some utilities want to take responsibility for home charging installation (if required) and we see this as an optimal solution because the consumer handholding, rate information availability and inspection would all be part of this process. Another solution would be a third-party service provider. We're still weighing all the options.

4:08	[Comment From Guest ] What is V2G?

4:08

Mark Duvall - V2G means Vehicle-to-Grid. A plug-in with V2G would have the ability to actually provide electricity to the grid from its battery for short periods of time. One example is you arrive home on a hot summer day when the grid is relatively stressed and electricity from your vehicle would reduce your house's load on the grid. It is envisioned that you would receive incentives for doing this, possibly small payments, which could add up over time, or inexpensive electricity when you recharged later that night

4:08	[Comment From Philipp Andres ] Does the Chevy Volt come V2G enabled? For example does it have two way power flow capabilities and the ability to record such power flows?

4:10	Britta Gross - Not at launch of the first generation Volt. This is something we are going to continue to look at as we learn what the impact to overall battery durability will be since it is additional use of the battery beyond driving.

4:10	[Comment From Guest ] How long does it take to charge a volt

4:11	Britta Gross - About three hours at 240 V and about eight hours at 120 V

4:12	[Comment From Philipp Andres ] What is the estimated lithium-ion battery life for the Chevy Volt and have you finalized your selection of battery vendors or are you developing those batteries internally?

4:13	Britta Gross - Our testing requirements are 10 years and 150,000 miles. LG Chem is supplying battery cells for Gen 1 Volt and we are assembling the battery packs ourselves in Michigan.

4:14	[Comment From Ryan P ] In charging at 240v or 120v, is there a detriment to battery life for one or the other?

4:17	Britta Gross - We're still studying this to see if there is any significant or perceptible difference in impact to the battery from different charging rates.

4:17	[Comment From Jim Mbongo ] Can I drive my Chevy Volt for 6 months (e.g.) without using a drop of gas? And in this case, what should I do to keep the engine/genrator?

4:20

Britta Gross - You can drive this vehicle all electric all the time and we have anticipated the case where a consumer doesn't use any gas yet we don't want engine problems so we've designed the engine to start periodically (and unnoticeably) and to stir the tank to prevent any mechanical or stagnant fuel issues.
