System and method for charging portable electronic devices

摘要

A device charging system that uses the fact that individual devices do not need to be continuously charged for an extended charging period in order to be fully charged at the end of the period. With automatic timing and switching, different devices can be charged at different times during the charging period with the result that all the devices are fully charged at the end of the period. Several charging power boxes that fit into one or more charging cabinets that are controlled by one or more timers. Each charging power box also includes a heat sensor and circuit breaker. User appliances or electronic devices can be stacked in the cabinets, plugged into numerous outlets available on the charging power boxes and then locked inside the cabinet for overnight charging and security. Any abnormal rise in temperature within the cabinet can shut down the entire charging process.

主权项

1. A device charging system comprising:
a plurality of charging boxes, each including a heat sensor and one or more groups of AC charging outlets; a charging control timer connected to said charging boxes that switches different of said groups of AC charging outlets on and off at predetermined times such that total AC current draw at all times is less than a predetermined current value; and, wherein the heat sensor located in each of said charging boxes is adapted to independently shut down charging on a box at or above a predetermined temperature.
