BATTERY-CELL CONVERTER SYSTEMS
First Claim
1. A battery-cell converter system, comprising:
- one or more battery-cell converter units, wherein each battery-cell converter unit comprises;
an electrical energy storage cell bank comprising of a plurality of energy storage devices, wherein each energy storage device comprises a first terminal and a second terminal, and wherein the first terminal corresponds to a positive terminal or a negative terminal, and the second terminal has an opposite polarity from the first terminal;
one or more DC/DC converters, wherein each DC/DC converter includes one or more inputs and one or more outputs;
one or more electrical connection devices coupled to the plurality of energy storage devices and said one or more DC/DC converters; and
a monitor and control module coupled to the plurality of energy storage devices, said one or more DC/DC converters, and said one or more electrical connection devices to monitor and control said one or more battery-cell converter units, wherein each energy storage device is connected to at least one input of said one or more DC/DC converters in at least one configuration of said one or more electrical connection devices as configured by the monitor and control module; and
wherein said one or more battery-cell converter units are configured to provide one or more regulated main power outputs from said one or more outputs of said one or more DC/DC converters of said one or more battery-cell converter units.

Abstract
A battery-cell converter (BCC) management system is disclosed. The BCC system comprises one or more battery-cell converter units that are configured to provide regulated main power output from the outputs of DC/DC converters inside the battery-cell converter units. Each battery-cell converter unit comprises an electrical energy storage cell bank, one or more DC/DC converters, one or more electrical connection devices and a monitor and control module coupled to other components of the battery-cell converter unit. Multiple battery-cell converter units can be stacked in series to increase output voltage. In another embodiment, multiple battery-cell converter units can be connected in parallel to increase output current. Accordingly, the BCC management system disclosed improves battery pack usage efficiencies, increase battery pack useable time per charge, extend battery pack life-time as well as lower battery pack manufacturing cost.
