Multi-port reconfigurable battery
First Claim
1. A multi-port reconfigurable battery, comprising at least one bank of:
- a statically joined plurality of series connected battery cells;
each of said battery cells comprising a first voltage pole and a second voltage pole; and
a plurality of ports, each port comprising;
at least one processor controlled switch electrically connected between said first voltage pole of each of said battery cells and a first electrical output connection, andat least one processor controlled switch electrically connected between said second voltage pole of each of said battery cells and a second electrical output connection;
wherein said processor controlled switches are adapted to electrically reconfigure said battery cells by coupling a first voltage pole of one of said battery cells to said first electrical output connection and a second voltage pole of one of said battery cells to said second electrical output connection to provide a reconfigurable battery output voltage between said first and second electrical output connections.

Abstract
A multi-port reconfigurable battery has at least one bank of statically joined series connected battery cells, each including a positive and negative pole connected through switches to respective output connections on at least one port. Processor controlled switches reconfigure the cells to provide power for electrical loads on one or more ports and simultaneously provide charging on one or more other ports. An alternative configuration divides groups of series connected cells into separate battery banks that permit other configurations. Ports are configurable to share one electrically common connection with other ports providing a simplified configuration (multi-tap reconfigurable battery). Applications include selectable motor speed control and battery regeneration schemes matched to motor output, and single or multiphase AC power output at selectable frequencies for use as an Uninterruptible Power Supply. The battery is also described as a power source for a forced-air induction system (e.g. electric supercharger) for a combustion engine.
