Degradation trajectory

SoH history + linear projection to 80.0% end-of-life

Charge–discharge optimization

engine-generated actions, highest leverage first

Raise the reserve floor — cap depth-of-discharge near 80% (avg 86%)

Repeated deep discharge accelerates capacity fade. A 10–15% SoC reserve materially slows aging.

Hold depot charge ceiling at 80% SoC unless full range is scheduled

Time spent at high state-of-charge is the dominant calendar-aging driver. Charge-to-need before departure.

Enable active pre-conditioning and cooling before fast charge; inspect coolant loop

Elevated pack temperatures and thermal excursions were logged. Keeping cells under 35°C during charge cuts fade sharply.

Schedule cell-balancing and a full capacity test at next service

Rising internal resistance / non-linear fade suggests cell divergence. Balancing recovers usable capacity and flags weak modules.

Prioritise teardown inspection and plan replacement or second-life redeployment

Asset is at or near end-of-first-life. Grid-storage second life can recover residual value below 80% SoH.
