Is the patent for Powerwall v2 available somewhere as well? As per https://www.tesla.com/blog/all-our-patent-are-belong-you? Just windering if it contains enough info for anyone to built a unit themselves.

The software is the special sauce. You could build your own PowerWall easily: it's just a battery box. The battery management system is the hard part.

It's not just a battery box. There's some pretty advanced liquid cooling and an inverter in there.
