Based on the power requirements and battery size, we compute the capital expense associated on a per-charger basis for each option. The main cost components are: installation, hardware, and battery price. Installation (C I ) includes expenses associated with electrical wiring, connections, permits, labor, and more. Hardware (C H ) refers to the cost of the high power DC charging modules used to deliver electricity to the truck. We use literature values reported by Nicholas for installation and hardware costs per charger, which are similar to costs reported by Burnham et al. and Nelder and Rogers 88 . For option 1, installation and hardware costs are $18,577 and $75,000 respectively. For option 2 we approximate the costs to be equal to the 50 kW scenario by Nicholas . The installation and hardware costs are $17,692 and $28,401 respectively. We have a higher cost for option 1 because it needs electrical systems that can handle a larger power load. The battery cost (C battery ) is considered as a parameter whose values range from 110 USD/kWh to 70 USD/kWh based on current and future projections of battery costs. There are several other capital expenses, such as land and construction costs, associated with building a charging station, which are incurred equally by both options. However, for this analysis, the key metric is the difference in the capital costs between options 1 and 2. Hence, these expenses are not considered in this study. The excess capital cost for option 2 is computed using Equation ,
