AutoblogGreen Q&A: The latest on Volt batteries

ABG: There was a story that came out recently from an unnamed internal source on a site that shall also be nameless for the moment. It claimed that the CPI batteries were nowhere close to what was required as far as performance. Can you comment on that?

Denise Gray: No, they are per what we thought they were going to be for this particular iteration. We wanted to get it on the bench. So it is more biased toward power than the total energy, that is total energy under all different circumstances but we are giving the energy that we need under the various task conditions that we are currently have. So, I think that was bogus. It's giving us what we think we're going to get at this first design iteration.

ABG: How is the thermal performance of the batteries looking so far?

Denise Gray: So far so good and, ironically, in this first iteration of the design we actually ran it the without thermal system and quite frankly the temperature rise over the battery, a test that is part of what we run went under. It was very small, a couple of degrees of temperature rise. So, quite frankly, it is very surprising that it actually performed that well without any kind of thermal management system.
