GS Yuasa Lithium Power announced the availability of a new, space-qualified lithium ion (‘Li-ion") battery based on the existing/successful LSE190 cell manufactured by GS Yuasa Technology (‘GYT’) in Kyoto, Japan. A 12-cell configuration of the MA190 battery module successfully completed qualification testing including shock, sine and random vibration, and thermal vacuum testing.  The MA190 can be assembled to contain 6 to 12 LSE190 cells per module with flexibility to connect cells in parallel.  For qualification, a 12-cell module was tested because it’s thermal behavior and environmental tolerance envelopes those of smaller module configurations.  The LSE190 is part of GYT's generation III Li-ion family of cells.  It has been qualified to NASA JSC 20793 ‘Crewed Space Vehicle Battery Safety Requirements’ and has accrued significant spaceflight heritage in LEO and GEO regimes including multiple human-rated missions.  The LSE190 is the larger of five space-qualified wound prismatic cell sizes offered by GS Yuasa and represents the portfolio's lowest cost in terms of dollars per watt or watt-hour. The MA190 module was designed to support LEO, MEO and GEO missions and provides the flexibility and scalability needed for optimal alignment with system requirements. Modules can be configured and deployed in battery systems with nominal voltages from 22 to more than 100 and support spacecraft power from 1kW to more than 30kW. Features of the MA190 include: Individual cell temperature sensing; Redundant individual cell voltage sensing; Protected telemetry connections; Redundant cell heater circuits and Optional cell bypass capability.
