Tesla has announced the expansion of its Powershare Home Backup capability, a feature that allows electric vehicles to function as a home energy source during power outages. Previously exclusive to the Cybertruck, this bidirectional charging functionality is now being extended to the Model 3 and Model Y.

To utilize this feature, customers must have a Powerwall 3 installed at their residence. While the current rollout is limited to this specific hardware, Tesla has indicated that compatibility with the Powerwall 2 and Powerwall Plus is currently in development and will be released soon.

Tesla is not the first manufacturer to introduce vehicle-to-home (V2H) charging. Other automakers have established similar technology, including Kia and General Motors, which offer various forms of vehicle-to-home power. Additionally, the Nissan Leaf has supported power-to-grid charging capabilities for several years. The expansion of this feature marks a significant shift in Tesla's ecosystem, as it integrates the vehicle battery more deeply into the home energy management system. The company has not yet provided a specific date for when the older Powerwall models will be compatible with the system, but it remains a primary focus for their upcoming software updates.
