Thermal Runaway Energy Release as a Function of the State of Charge

Designing safe products powered by lithium-ion batteries requires an understanding of how the battery pack will behave while undergoing thermal runaway. In this work, fractional thermal runaway calorimetry is used to estimate the energy release from cells at different states of charge when undergoing a thermal runaway.

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.
