New Research Explores Potential Value of Implementing EV Managed Charging To Move Toward Realizing Effective Vehicle-Grid Integration

It is 5 p.m., and you arrive home from work when it is peak demand for the grid. Your electric vehicle (EV) is 50% charged—you could either plug it in and charge right away or, if it works for your plans, schedule the vehicle to charge at a better time for the grid.

With more and more EVs on the road, the grid of the future can greatly benefit from EV managed charging, also called "smart" charging. EV managed charging coordinates charging based on people’s travel needs, electricity supply, and grid conditions. This flexibility could be especially valuable for the grid as it transitions to high shares of variable renewable generation, like solar and wind.

A team at the National Renewable Energy Laboratory (NREL) completed a literature review on the potential value of EV managed charging. Findings, published in an Energy & Environmental Science article, provide a complete look at how EVs and the grid could work together as the electric and transportation sectors become intertwined. Many studies have considered the benefits of EV managed charging, but this review summarizes findings from hundreds of studies considering multiple value streams for the power system, enablement costs, and perspectives of different stakeholders, including utilities, EV owners, charging station operators, and rate payers.
