But, http://www.a123systems.com/hymotion/technology/performance_data pg 8 of 12:
shows DoD (Depth of Discharge) limited down to 2 KWH.
Effectively a 180 pound 3 KWH battery w/5.5 hour recharge time.
60% DoD to extend the life of the Li-ion battery.

GM plans to keep the lithium-ion battery in a state-of-charge (SOC) range of between 30% and 80%, with the on-board generator starting to recharge the battery at the 30% level

Shallow cycling has less impact on battery lifetime than
the more commonly reported deep cycling. For example, test
data on a Saft lithium-ion battery show a 3000-cycle lifetime
at 100% discharge, and a 1,000,000-cycle lifetime for
cycling at 3% discharge [26].
