Tesla announced the Tesla Autopilot, a driver-assistance system, in 2014. In September that year, all Tesla cars started shipping with sensors and software to support the feature, with what would later be called "hardware version 1".
Tesla entered the energy storage market, unveiling its Tesla Powerwall (home) and Tesla Power-pack (business) battery packs in April 2015. The company received orders valued at $800 million within a week of the unveiling.
