This paper presents a lifecycle cost of ownership (LCO) model/software that includes the effects of real world driving and the uncertainty in the costs of gasoline and electricity in future years. The real world driving effects included are differences in driving cycle (speed and grade vs. time and distance) and the operation of the heating and cooling systems in the PEVs. The model is incorporated into a dynamic analytic tool that can be used to understand questions related to LCO. The effect of heating and cooling were analyzed by altering the accessory inputs to Advisor. The fuel economy outputs were then input to the LCO model along with relevant parameters such as fuel prices, vehicle cost incentives, costs for insurance, parking, and maintenance. The fuel and electricity prices were stochastically varied to simulate expected future increases and uncertainties. The output of the model is not a fixed cost but rather a distribution of expected costs that can have significant variation. The Advisor model runs showed that increased accessory loads from heating or cooling can have a large effect on fuel economy and range for vehicles operating in electric mode. The LCO varied up to 15% based on the choice of drive cycle. The stochastic treatment of fuel and gasoline prices resulted in spreads of the ownership costs of 10-20% for the PHEVs depending on their gasoline usage.
