Challenges in V&V testing and strategies to overcome them

Batteries are the costliest and most critical component of an electrical powertrain on an aircraft. They must be properly tested for functionality, performance, durability and SOC/SOH. These tests may become complex and can take an impractical amount of time and resources. For new programs, the engineering team may be concerned about how much testing is sufficient and how they can efficiently complete battery V&V testing. This session will outline industry expectations of battery V&V. It will describe what tests should be done on battery cells, modules, packs and electronics, and will define a cost-effective and time-efficient test workflow. Test standards, cycling profiles, test cases and performance expectations will be evaluated over all stages of battery development, from performance evaluation and functional validation, to environmental and durability testing, to end-of-line production test, to warranty and end-of-life testing.
