EVs supplying power to homes can cut up to 90% charging costs

A recent study by researchers from the University of Michigan and Ford Motor Company reveals that electric vehicle-to-home (V2H) energy supply can reduce EV charging costs by up to 90%, potentially saving homeowners between $2,400 and $5,600 over the vehicle’s lifetime. V2H utilizes bidirectional charging technology, allowing EV batteries to power homes much like a generator but without burning fossil fuels. This system enables homeowners to purchase electricity when it is cheap and clean—such as during peak solar power production—and store it in their vehicle’s battery for later use, thereby cutting both energy costs and greenhouse gas emissions from the building sector. The study, which analyzed a mid-sized SUV across 432 U.S. regions with varying climate and grid conditions, found that V2H could reduce a homeowner’s lifecycle greenhouse gas emissions by 70 to 250 percent, equivalent to offsetting 24 to 57 tons of CO2 or 80 to 190 one-way flights between New York and
