EVI-X Modeling Suite of Electric Vehicle Charging Infrastructure Analysis Tools

NREL's EVI-X modeling suite informs the development of large-scale electric vehicle (EV) charging infrastructure deployments—from the regional, state, and national levels to site and facility operations.

In addition to identifying the number and type of chargers needed to meet a given demand, EVI-X enables researchers to pinpoint efficient charging station locations and find ways to mitigate the impact of charging loads on the electric grid—by tapping into renewable energy and employing smart-charge technologies.

Integrated Analysis Tools

NREL's EVI-X modeling suite of charging infrastructure analysis tools equips researchers with the integrated resources needed to conduct multifaceted analyses providing insight critical to the development of successful charging networks that meet the needs of users while supporting the grid.
