An Overview of Aerospace Battery Compliance

The United States Federal Aviation Administration (FAA) has published requirements that require testing for all battery devices that are a part of the aircraft itself. This testing is heavily based on standards published by RTCA and includes primary and secondary lithium, nickel, and sealed lead chemistries.

Calibrating Smart Batteries with Impedance Tracking

When Gaston Planté invented the rechargeable battery in 1859, a new system of stored energy emerged. Today, digital technology has helped to make the electrochemical battery smart by providing a window into a battery’s state-of-function.

Energy Release Quantification for Li-Ion Battery Failures

The growing application of lithium-ion batteries brings with it an increased risk of unanticipated energy releases and thermal runaway. Quantifying battery energy release characteristics during product design can help mitigate those risks.

Health Monitoring and Prediction of Cells in a Battery Module or Pack Under Operating Condition

The state of health of cells in a battery pack under operating condition is difficult to obtain through existing IEC and ISO standard methods under laboratory conditions. However, a cell state of health (SOH) profile shall be able to establish by the comparison of electro-impedance spectroscopy (EIS) generated statically versus dynamic operating data retrieved by battery management system (BMS) communication interface as fragments of EIS.
