Host machines for battery charging system

This invention describes a charging station for wireless device batteries. It has multiple slots to charge batteries and keeps a supply of fully charged batteries ready for use. The station can also identify when a battery needs replacing and suggest where to buy a new one, or help manage swapping out nearly drained batteries for fully charged ones.

Why it matters: Filed before widespread cloud computing and robust IoT networking. Building a distributed system to share batteries and integrate e-commerce was significantly more complex and costly in 2007 than it is with today's mature cloud platforms and API ecosystems.
