Internal resistance climbingmedium
DC internal resistance up 31% vs beginning-of-life — power fade and heating risk.

Charge–discharge optimization
engine-generated actions, highest leverage first
Charging~+105d life
Cap DC fast-charge share below 25% (currently 50%)
High-C-rate sessions drive lithium plating and heat. Shift toward overnight AC charging where the duty cycle allows.
Charging~+40d life
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.
Thermal~+140d life
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.
Balancing~+25d life
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.
