Tesla

Tesla sells Megapack battery systems that are now being deployed around AI data-center sites and by AI companies themselves. Its energy business has become a practical way to add flexible capacity and reliability before grids catch up. Tesla also trains large vision and action models for FSD and the Optimus humanoid using data from its vehicle fleet, but neither model is available outside Tesla hardware, so they are not carded separately.

Ecosystem functionTesla is the biggest storage brand in the AI power stack, with the manufacturing scale and brand recognition that most specialist storage firms lack.
