We report our TCO results in Figure as a cost per distance traveled to deliver the same average payload as a diesel truck. For long-haul trucks, the operating cost (fuel, labor, and more) is the largest contributor for all scenarios. Over time, we expect a decrease in the contribution of electricity towards operating costs owing to improvements in battery energy density, battery lifetime and projected decreases in delivered electricity prices. Therefore, we find that electricity is the largest portion of the operating cost for the present-day and midterm scenarios, but labor becomes the major contributor in the long term. Additionally, the payload penalty factor also decreases which translates into a lower operating cost. Capital cost also follows the same decreasing trend over time. This is due to the reduction in battery pack prices, and similar to operating cost, it also benefits from the decrease in the payload penalty factor. scenarios use the cost of electricity delivered to the truck at 0.32 USD/kWh, while the long term uses 0.15 USD/kWh. The baseline diesel uses pre-pandemic with-out-tax fuel costs of 2.5, 2.73 and 3.13 USD/gallon, respectively. Projections are for the baseline cases; however, the actual numbers could differ due to the large variability of certain parameters.
