HV Battery — Battery Has Reached End of Life

The SME constantly tracks the pack's overall health (capacity, internal resistance, cell-to-cell balance) and computes an overall aging indicator. When this indicator crosses the threshold set by BMW, the battery is flagged as end-of-life — not necessarily fully non-functional, but below the guaranteed minimum performance level.
