General Motors (GM) is expanding the role of electric vehicles beyond transportation by promoting bidirectional charging technology, which allows compatible EVs to both receive and supply electricity. The company says the innovation can help power homes during outages and support local electrical grids during periods of high demand.
Unlike conventional electric vehicles that only draw electricity from charging stations, GM’s latest EV models—including the Chevrolet Equinox EV, GMC Sierra EV, and Cadillac LYRIQ—are designed with bidirectional charging capability. This technology enables two key functions: Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G).
Through the V2H system, compatible GM EVs can act as backup power sources for homes. During power outages caused by storms or other disruptions, electricity stored in the vehicle’s battery can be used to operate essential household appliances such as refrigerators, lighting systems, and air conditioners. To access this feature, customers require a compatible EV along with GM Energy’s V2H equipment, including a bidirectional charger and enablement kit.
GM also highlighted the benefits of Vehicle-to-Grid technology, which allows EVs to send electricity back to the power grid through participating utility programs. The system is designed to help utilities manage electricity demand during peak periods, such as heat waves or winter storms, when power consumption rises sharply.
According to GM, V2G could reduce pressure on electrical infrastructure by enabling thousands of parked EVs to collectively supply energy to the grid. This may help utilities avoid relying on expensive and high-emission backup power plants while improving overall grid stability.
For EV owners, the technology offers potential financial benefits. Drivers may be able to lower electricity costs by supplying power during peak-rate periods and charging their vehicles when electricity prices are lower. In some regions, utility companies may also compensate customers who contribute energy back to the grid.
The company noted that growing electricity demand from data centers, increased electrification, and extreme weather events are placing additional strain on power systems worldwide. GM believes bidirectional charging presents a practical solution by transforming EV batteries into distributed energy resources.
As the adoption of electric vehicles continues to accelerate, GM’s bidirectional charging strategy positions EVs not only as transportation tools but also as valuable contributors to energy resilience, grid reliability, and household power security.
