Battery power delivery module
First Claim
1. An apparatus, comprising:
- input terminals configured to receive power from one or more battery cells;
output terminals configured to provide power to a load;
a capacitor connected to at least one of the output terminals;
an inductor; and
an integrated circuit connected to the input terminals, the inductor, and the output terminals, the integrated circuit comprising;
a DC to DC converter configured to provide an output voltage to the at least one of the output terminals; and
a processor connected to the DC to DC converter, the processor configured to determine a type of at least one of the one or more battery cells, wherein the processor is programmable to maintain output power characteristics at the output terminals according to programmed characteristics comprising at least one parameter of the load, and wherein the processor is programmable to control power draw at the input terminals according to programmed characteristics comprising at least one characteristic of the at least one of the one or more battery cells based on the type of the at least one of the one or more battery cells.

Abstract
A system and method for digital management and control of power conversion from battery cells. The system utilizes a power management and conversion module that uses a CPU to maintain a high power conversion efficiency over a wide range of loads and to manage charge and discharge operation of the battery cells. The power management and conversion module includes the CPU, a current sense unit, a charge/discharge unit, a DC-to-DC conversion unit, a battery protection unit, a fuel gauge and an internal DC regulation unit. Through intelligent power conversion and charge/discharge operations, a given battery type is given the ability to emulate other battery types by conversion of the output voltage of the battery and adaptation of the charging scheme to suit the battery.
