High-voltage High-power Battery Systems

APRI has built and is in the process of demonstrating a battery charge control system. The apparatus pictured below includes a battery pack with eight Li-ion cells, a resistive load, a power supply, and a personal computer which controls the experiment. The battery pack is cycled to simulate a typical LEO satellite mission, which is approximately 30 minutes in eclipse on battery power followed by approximately 60 minutes in the sun charging the batteries.

Experimental Battery Setup

Inquiries concerning APRI's battery charge control technology should be directed to Dr. Thomas Sobota at
