Industry Demand The emerging large constellation market is pushing for higher volume, lower cost batteries with demanding schedules. Questions the industry faces include what does this new demand mean, what will be the long term affects, what pressure will be passed onto suppliers, and will the risk tolerance change in proportion? If a higher risk tolerance is accepted for some missions, will the industry turn to commercially available products (such as commercial battery packs or batteries) qualified & characterized for space? As an industry, this market is asking all of us to look at methods for increasing throughput, design for manufacturability, modularity, and common systems. EnerSys Proprietary © 2015 EnerSys.
