Battery Testing, Analysis and Design
(Figure IV - 2). For the 70%-OCV battery pack, the cost saving of about $100 compared to the battery producing full power at 80% OCV does not appear to warrant the likely reduction in battery life that would result from the increase in the initial battery impedance. At 90% of OCV, the additional cost for the battery for almost
