GM Turns 246,000 EVs Into Home Backup Batteries

Imagine turning your electric car into a home battery that keeps your lights on when everyone else's go dark.

GM just made that possible for over 246,000 electric vehicle owners across America. The new GM Energy Home System lets drivers use their EVs to power their homes during outages, transforming everyday transportation into emergency backup power.

The technology works with GM's entire electric lineup, from the budget-friendly 2027 Chevrolet Bolt to the premium Cadillac CELESTIQ. Even a mid-range Silverado EV carries over 200 kilowatt-hours of battery capacity, enough to run an entire household for days.

One family learned about the system after enduring a four-day blackout. When they started shopping for traditional generators and battery backups, they discovered their GM vehicle could do the job instead. Now their EV serves double duty: commuting during the week and providing peace of mind during storms.

The GM Energy V2H Bundle includes a special charger and enablement kit that creates a two-way power flow. During normal times, the car charges from the grid. When the power fails, that stored energy flows back into the house, keeping essential systems running.

Homeowners can add GM Energy PowerBank batteries for even more capacity. These standalone units provide backup power even when the car isn't plugged in, storing up to 35.4 kilowatt-hours of additional energy.

The Ripple Effect

This technology represents a fundamental shift in how we think about electric vehicles. They're no longer just transportation; they're mobile power stations that strengthen household resilience against blackouts and extreme weather.

The system also helps families save money during peak electricity pricing by drawing power from stored battery reserves. When paired with solar panels, homeowners can capture free energy from the sun, store it in their vehicle or PowerBank, and use it whenever rates spike.

GM built this capability into every new EV rolling off their assembly lines, making advanced energy independence accessible across price points. Professional installers customize each setup based on local building codes and utility requirements, ensuring safe and reliable operation.

One quarter-million households now have access to technology that turns climate-friendly transportation into comprehensive energy security.
