The policy engine that ranks vehicles competing for limited stalls and power headroom, balancing route criticality, battery health, and V2G revenue opportunities across the whole fleet.
Each vehicle's priority score is a weighted sum of normalized inputs: hours until scheduled departure, current state of charge relative to the trip's energy requirement, a penalty multiplier for service-level-agreement routes, and a battery-health term that slightly deprioritizes cells already flagged for accelerated degradation. Weights are tunable per depot and re-evaluated on every scheduler pass.
Preemption cannot simply yank power from a mid-session vehicle without accounting for the minimum energy floor already promised to it. When a higher-priority arrival forces contention, the arbitration layer first checks whether any lower-priority session has already met its guaranteed minimum charge before selecting it for relocation to a lower-power stall or a later timeslot, rather than terminating the session outright.
