Portable power banks are becoming increasingly popular as a solution to power outages and emergencies. Electric vehicle makers like General Motors are now offering power solutions that pair with battery-electric cars, trucks, and SUVs to create a vehicle-to-home charging ecosystem. GM’s subsidiary, GM Energy, has introduced the PowerBank, a lithium-ion battery available in 10.6- and 17.7-kWh options that can power a home during emergencies or offset high electricity rates. By combining two 17.7-kWh batteries, the average American home can be powered for up to 20 hours. The system can be purchased as part of the GM Energy Home System bundle, which includes a GM Energy PowerShift charger and GM Energy Vehicle-to-Home Enablement kit.
Currently, under the General Motors banner, vehicles like the Silverado EV, Equinox EV, Blazer EV, GMC Sierra EV, and Cadillac Lyriq all feature bidirectional charging capabilities, meaning the vehicle battery can be used to power a home when needed. Ford also offers a bidirectional charging solution with their Power Station, which pairs with the Ford F-150 Lightning. However, the Power Station functions only as a charger and does not offer energy storage capabilities. Nissan also has a wall system called xStorage, although it is not currently available in the U.S. Tesla, a key competitor to GM in the home energy storage market, sells the Powerwall, which can store solar or grid energy and be used during peak demand or power outages. Their latest generation, Powerwall 3, has an energy capacity of 13.5 kWh and offers the ability to be upgraded and expanded for more power.
The concept of a vehicle-to-home charging environment is a significant advancement for both automakers and homeowners. This solution allows homes to charge cars and cars to charge homes, as well as return excess energy to the grid. This reduces reliance on public charging infrastructure and utility companies, offering a more sustainable and efficient energy solution. Many electric vehicles, including Hyundai Motor Group, Volkswagen ID.4, Polestar, Porsche Taycan EV, Jeep Wrangler 4xe, and Lucid Air, now offer bidirectional charging capabilities. The Ford Lightning made headlines during the 2021 Texas power outage for keeping a man’s house powered for days. By introducing V2H solutions alongside electric vehicles, automakers are making this technology more accessible and familiar to buyers.
Overall, portable power banks and vehicle-to-home charging solutions are transforming the way we think about energy storage and distribution. With automakers like General Motors, Ford, Nissan, and Tesla offering innovative solutions, homeowners have more options for powering their homes and vehicles during emergencies or peak demand. The flexibility and modularity of these systems, combined with a growing lineup of bidirectional charging vehicles, offer consumers more control over their energy usage and cost savings. As the market for portable power banks and home energy storage solutions continues to expand, we can expect more advancements in this area and greater adoption of sustainable energy solutions.
