A system and method for estimating an accumulated total battery aging over different aging patterns. A first aging pattern, first aging time, and aging model are used to determine a battery aging estimation. The aging model, battery aging estimation, and a second aging pattern are used to determine an equivalent previous aging time. By adjusting a second aging time based on the equivalent previous aging time, and applying the adjusted second aging time and second aging pattern to the aging model, a battery accumulated aging estimation is determined for the duration of the first and second aging patterns. The process can be repeated for each next aging pattern, with an equivalent previous aging time being determined for each next aging pattern and used with an associated next aging time, aging model, and next aging pattern to determine an accumulated total battery aging estimation.
