Information handling system battery emulation testing system and method
First Claim
1. A system for testing an information handling system, the system comprising:
- a battery connector operable to electrically couple with a battery port of an information handling system under test to transfer power and management information;
a programmable power supply interfaced with the battery connector and operable to provide a simulated battery discharge at the battery connector for transmission to the battery port, the simulated battery discharge having predetermined battery discharge parameters;
a programmable load interfaced with the battery connector and operable to accept an information handling system charge from the battery port through the battery connector, the programmable load having predetermined battery charge parameters;
a management bus controller interfaced with the battery connector and operable to communicate management information through the battery port to the information handling system under test;
a battery emulator interfaced with the programmable power supply, programmable load and management bus controller, the battery emulator operable to apply charge and discharge characteristics of a predetermined battery to emulate the predetermined battery discharge parameters, charge parameters and management information associated with the predetermined battery; and
a battery table interfaced with the battery emulator, the battery table storing plural battery types by battery type identification information, each battery type identification information having associated charge and discharge characteristics;
wherein the battery emulator is further operable to retrieve battery type identification information from the information handling system under test and to automatically apply the battery type identification information to select the predetermined battery type to emulate from plural battery types of the battery table by applying charge and discharge characteristics retrieved from the battery table.

Abstract
Information handling systems are tested for proper interaction with integrated batteries by simulating a battery connection at a battery port of the information handling system. A battery connector couples to the battery port and communicates through cables with a management bus, a programmable power source and a programmable load. The management bus supports communication with a battery management unit that imitates responses for the information handling system that are expected from a battery. A battery emulator controls the programmable power source and load to provide the information handling system with an expected battery response for confirming proper operation of the information handling system power subsystem without requiring insertion of an actual battery.
