Budget Types:
timeMinutes: Travel time in minutes (isochrone)distanceKM: Travel distance in kilometers (isodistance)remainingChargePCT: Remaining battery charge in percentage (EV)spentChargePCT: Battery charge consumed in percentage (EV)spentFuelLiters: Fuel consumed in liters (combustion)Both charge budgets are converted against the battery capacity, so they need an electric
vehicle with model.engine.charging.maxChargeKWH; remainingChargePCT also needs its current
charge in vehicle.state.
Common Use Cases:
Type of budget constraint for reachable range calculation.
