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.

21. An apparatus, comprising:
-
input terminals for receiving power from a battery cell; an output terminal for providing power to a load; one or more telemetry terminals for communicating operation data; and a power converter programmable to maintain output power characteristics at the output terminal and to control power draw at the input terminals according to programmed characteristics, and wherein the power converter uses the one or more telemetry terminals to receive a state of charge of the battery cell, a state of health of the battery cell, an internal temperature of the battery cell, a date of production of the battery cell, a number of charge cycles of the battery cell, or information indicating a type of the battery cell. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
