This is the data repository for the NCST project titled "Integrated Modeling Program and Total Cost of Ownership Calculator for Medium-Duty and Heavy-Duty Battery Electric Trucks in Regional Freight Use-Case Deployments." A hypothetical regional container drayage use-case example was developed using quantitative and qualitative data, to which the Total Cost of Ownership Spreadsheet Tool (TCOST) was applied to demonstrate the application of the tool and its value to fleet managers and policymakers in its ability to model the cost effects of minor parameter adjustments or the multiplicative effects of simultaneous parameter adjustments quickly and easily.
