EVI-X Modeling Suite of Electric Vehicle Charging Infrastructure Analysis Tools
NREL's EVI-X modeling suite informs the planning and development of large-scale electric vehicle (EV) charging infrastructure deployments—from the regional, state, and national levels to site and facility operations.
Three Types of Tools
Network Planning
Use these tools to quantify charging infrastructure needs such as:
- Number, type, and location of charging ports
- Recommended power levels and grid impacts
- Practical control strategies to counter EV charging loads
- Accessible and affordable charging
- Optimized charging for fleets and ride-hailing services
- Long-distance travel along highway corridors
- Utility partners for infrastructure installation.
Site Design
Use these tools to inform charging station design for:
- Dynamic roadway charging feasibility
- Energy estimation and site optimization
- Optimal sizing and control of behind-the-meter storage
- Composition and size of EV fleets
- Optimal placement of charging station equipment.
Financial Analysis
Use these tools to assess costs associated with charging infrastructure such as:
- Station and network economics
- Levelized cost of charging
- Investor payback period and risk analysis.
