Battery power delivery module
First Claim
1. An apparatus, comprising:
- input terminals configured to connect to a battery module;
output terminals configured to provide power from the battery module to a load;
one or more telemetry terminals configured to receive operational data from the battery module, wherein the operational data comprises at least one of an internal temperature of the battery module or a state of charge of the battery module; and
a power converter configured to;
output power at the output terminals;
draw power at the input terminals;
charge the battery module; and
communicate the operational data to a host device.

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.

18. A method, comprising the steps of:
-
receiving battery power, at input terminals of a power converter, wherein the battery power comprises a first voltage; converting, using the power converter, the battery power at the first voltage to converted power at a second voltage; providing the converted power at the second voltage to a load using output terminals of the power converter; sending, using one or more telemetry terminals of the power converter, operational data to a host device, wherein the operational data comprises at least one of an internal temperature of at least one battery cell or a state of charge of the at least one battery cell; and charging, using the power converter, the at least one battery cell. - View Dependent Claims (19, 20)
