About Us

Plug-In Supply was formed in August 2007 to design, develop, and produce advanced technology battery packs. The primary focus has been to use these packs to convert hybrid cars into plug-in hybrid cars. The overarching philosophy of the company is to help speed the world's transition from burning fossil fuels to using sustainable, renewable, zero-emission power systems. For vehicles, that means electric cars.

From the beginning we have been a small group of Silicon Valley engineers working to develop cutting-edge battery pack technology. Some of the best minds in the San Francisco Bay Area have contributed to our technology. The Bay Area is the center of the electric vehicle (EV) world.
