“…e) In [211] and [212], additional perturbations are injected into the reference point (B2-based scheme) and controller (B3-based scheme) of balancing circuits, which are similar to that in schemes A2 and A3. In [234]- [236], the MOSFETs in the balancing circuits are linearly controlled during balancing processes, in order to form disturbance in voltage and current. However, the amplitude of perturbation is relatively small, which increases the difficulty of the sampling circuits.…”

Safety enhancement for lithium-ion batteries (LIBs) has received a lot of attention from academic and industrial fields. However, there is a lack of overview from the perspective of the application power electronics (PEs) in the systems. This article gives an overview of PE-based safety enhancement technologies for LIBs, mainly focusing on battery management. It introduces the latest advances in battery protection, balancing, monitoring, and lifetime improvement, all based on PE technologies. Detailed discussion and future research opportunities are given. This article aims to provide a reference for PE researchers who want to make some efforts in LIB safety.

“…Cell‐to‐cell variation, although statistically challenging to account for, should be considered by including more cells in those tests whose conditions promote dominant degradation mechanisms, such as tests at 45°C and −15°C. When running tests, we also recommend periodic cell characterizations every 100 days, including electrochemical impedance spectroscopy (EIS), which is proven as an efficient aging diagnostic tool that could help to identify degradation modes . Finally, tests at sub‐zero temperatures become optional in those geographies where these ambient temperatures are not expected.…”

Summary This work summarizes the findings resulting from applying an aging modeling approach to four different capacity loss experimental datasets of lithium‐ion batteries (LIBs). This approach assumes that the degradation trajectory of the capacity is a function of three variables: time, kinetic constant, and time‐dependent factor. The analysis shows that the time‐dependent factor α is cell‐chemistry dependent and cannot be averaged for calendar and cycling modes and combined modes. This factor was also found to be a function of the stress factors. A quadratic model was used to obtain the kinetic constants per test, and statistical metrics were provided to evaluate the quality of the fitting, which was significantly affected when using averaged values of α and refitted kinetic constants. A set of test matrices is proposed for calendar, cycling, and mixed aging modes to overcome the challenges of data‐based models developed from accelerated test approaches for modeling aging in LIBs. This work also proposes a methodology to develop these data‐based aging models.
