The as 12 cell version of the MA190 battery module developed by GS Yuasa Lithium Power in the US has successfully completed qualification testing including shock, sine and random vibration, and thermal vacuum testing.This is based on the existing LSE190 cell manufactured by GS Yuasa Technology in Kyoto, Japan.

The MA190 can be assembled to contain 6 to 12 LSE190 cells per module with flexibility to connect cells in parallel, providing nominal voltages from 22V to more than 100V for spacecraft power from 1kW to more than 30kW.  For qualification, a 12-cell module was tested as the thermal behaviour and environmental tolerance covers the smaller module configurations.   

The LSE190 is part of GYT’s generation III Li-ion family of cells and is the largest of five space-qualified wound prismatic cell sizes offered by GS Yuasa.  It has been qualified to NASA JSC 20793 “Crewed Space Vehicle Battery Safety Requirements” and been used for LEO and GEO satellites. as well as multiple human missions.

“Maximizing the accessibility of GYT’s industry leading space Li-ion technology in North America through high TRL and complete battery offerings continues to be GYLP’s focus” said Bill Moll, President of GYLP in the US. “Developed to complement GYT Li-ion based batteries available from our partner EaglePicher Technologies, the MA190 reflects our effort to bring the best possible value to our customers.”

The MA190 module was designed to support LEO, MEO and GEO missions and provides individual cell temperature sensing, redundant individual cell voltage sensing and protected telemetry connections. It also includes cell balancing connections, redundant cell heater circuits to maintain the operating termperature in space and an optional cell bypass capability.
