The EV Charging Cost Calculator is a python-based tool that calculates the electricity costs for charging a private electric vehicle (or fleet of electric vehicles on the same meter) or a public electric vehicle charging station. The main purpose of this tool is to enable cross-rate analyses of charging costs for any EV charging scenario. For example, it could be used to calculate the cost to operate a public DCFC charger across all supported utility rates available in the OpenEI Utility Rate Database.
The tool is flexible and supports a wide range of charging scenarios, from large fleet installations or high-power charging sites to small fleets and individual vehicles. Thus, the tool does little to limit the types of rates included in its analysis. As documented in the user guide, users are responsible for filtering outputs to remove those rates not applicable to the use case they are modeling. Failure to limit results to applicable rates will result in invalid cost estimates.
The EV Rate Calculator is licensed under the MIT License and is free to use and modify. The tool is provided as-is and with no warranty.
