Control circuit
First Claim
1. A control circuit for a load, the circuit including:
- input terminals for electrically connecting with respective terminals of a battery that has a predetermined maximum operational current whereby the battery supplies a battery current;
output terminals for electrically connecting in parallel the load and a supercapacitor; and
a controller being disposed between the input and the output terminals for allowing the battery to transfer energy to the load and the supercapacitor while maintaining the battery current at less than the predetermined maximum operational current wherein the load draws a load current that varies with time, where the load current is the sum of the battery current and the current provided by the supercapacitor; and
wherein the load current is greater than or equal to zero and the controller maintains the battery current at greater or equal to zero.

Abstract
A control circuit (101) is configured for use with a load in the form of hardware (102) of a laptop computer (103). Circuit (101) includes input terminals (105, 106) for electrically connecting with respective terminals (107, 108) of a battery pack (109). The battery pack (109) supplies a battery current and has a predetermined maximum operational current. Circuit (101) also includes output terminals (111, 112) for electrically connecting in parallel hardware (102) and a supercapacitor (113). A controller (115) is disposed between the input and the output terminals for allowing the battery to transfer energy to hardware (102) and supercapacitor (113) while maintaining the battery current at less than the predetermined maximum operational current.
