DEPOT_SCHEDULER
Departure-deadline charge scheduling with time-of-use cost shifting and an early deadline-miss alarm.
When to use it
Use DEPOT_SCHEDULER when a depot vehicle must reach a departure state of charge by a known time, charging is worth shifting into cheap tariff windows, and the operator has to be told EARLY when a departure cannot be met.
