General Motors Making Bidirectional Charging Tech Available on Upcoming Ultium-based EVs

General Motors is taking a significant step in the realm of electric vehicle (EV) technology by introducing bidirectional charging capabilities to its upcoming lineup of Ultium-based EVs. This innovative feature, known as vehicle-to-home (V2H), empowers users to utilize their EVs as backup generators by exporting power from the vehicle’s high-voltage batteries to their homes.

Initially introduced for the 2024 Chevrolet Silverado EV RST pickup, General Motors has now expanded this feature across its entire range of new Ultium-based EVs until the 2026 model year. This inclusive approach means that models like the 2024 GMC Sierra EV Denali Edition 1, 2024 Chevrolet Blazer EV, 2024 Chevrolet Equinox EV, 2024 Cadillac Lyriq, and the forthcoming Cadillac Escalade IQ will all be compatible with V2H technology.

However, it’s essential to clarify that this offering is limited to General Motors’ new Ultium-based EVs and doesn’t encompass models such as the GMC Hummer EV, at least for now. Nevertheless, it’s worth noting that General Motors had previously announced plans to equip the 2024 Hummer EV pickup and SUV variants with a more potent Level 2 onboard charger, standard on some trim levels. This upgrade enables vehicle-to-load (V2L) functionality, allowing users to extract power from the battery at up to 6 kW through an adapter.

For customers to leverage the V2H feature, they will need to enhance their residential setups with one of three equipment bundles disclosed by GM Energy. These options include the Ultium Home V2H Bundle, the Ultium Home Energy System, and the Ultium Home Energy Storage Bundle.

The first package comprises an AC charger with bidirectional charging capabilities and an Enablement Kit featuring an inverted and “dark start” battery. With this foundation, EV owners can recharge their vehicles at a maximum rate of 19.2 kW and, when necessary, supply their homes with power from the EV’s high-voltage battery at a peak discharge rate of 9.6 kW.

The Ultium Home Energy System takes the concept a step further by incorporating a GM PowerBank stationary storage unit connected to the V2H Enablement Kit. Two versions are available: a 5 kW/10.6 kWh variant and a 7 kW/17.7 kWh variant.

The third offering, the Ultium Home Energy Storage Bundle, combines one of GM’s PowerBank offerings, an inverter, and a home hub. This bundle is tailored for individuals seeking backup battery storage without owning an electric vehicle.
