The work in this paper continues the development of a portable power supply suitable for use with a portable colposcope, an instrument used by doctors to diagnose whether a woman has cervical cancer. This paper explains how the system works, but it is software-related and describes the program that was written for the system. The program is intended to manage the system efficiently, allowing the portable colposcope to function properly for the longest amount of time possible without repair. Among the program’s responsibilities are 1) choosing whether the battery packs which allow the device to be portable, grid power, or automobile power is the appropriate power source to run the system, 2) re-charging depleted battery packs when automobile or grid power is available, and 3) taking appropriate action when any of the battery packs notifies the system of a critical condition or alarm situation.
