What is ISO/TR 20891 about?
ISO/TR 20891 is an international standard that covers specifications for systems and batteries used in space.
ISO/TR 20891 specifies provides detailed information on the specifications of spacecraft telemetry and resulting limitations, methods for evaluating the battery aging parameters, various methods of assessing the health status of lithium-ion space batteries in flight, and makes recommendations to battery suppliers, spacecraft manufacturers, and operators to ease this assessment.
Who is ISO/TR 20891 for?
ISO/TR 20891 on Space systems is applicable to:
- Space research organizations
- Aerospace constructors
- Space research scientists
- Spacecraft design engineers
- Spacecraft batteries manufacturers
Why should you use ISO/TR 20891?
Understanding the battery’s performance throughout the mission is very essential, as the charge and discharge cycle of a battery is not 100 percent efficient.
ISO/TR 20891 provides you with test procedures and requirements for the health status of lithium-ion space batteries in flight and accumulates and causes degradation of the performance of the battery. This aids in the improvement of in-flight battery performance.
ISO/TR 20891 helps in analyzing how the battery's performance during the mission and provides an accurate assessment of the battery’s current SoH in a variety of scenarios during the actual operation of batteries in spacecraft.
ISO/TR 20891 helps to provide detailed information on the methods now used or planned for assessing in-flight battery health as well as to make recommendations to spacecraft manufacturers, operations managers, and battery manufacturers to make it easier.
