Abstract
A system and a method for determining charging and discharging power levels for a battery pack are provided. The battery pack has an enclosure holding a battery module therein. The system includes a computer that determines a temperature correlation value based on first and second temperature values associated with the battery pack. The computer determines a third temperature value indicative of a temperature level of a first battery cell disposed adjacent to the end of a housing in the battery pack based on the first temperature value and the temperature correlation value. The computer determines a desired charging power level for the battery pack based on the third temperature value.
