The need to increase the charging speed of lithium-ion (Li-ion) battery energy storage systems (BESS) has led to the usage of high-voltage (HV) battery packs in e-mobility applications. External short-circuits (ESCs) might lead to high current rates far beyond the nominal current of a battery pack and hence impose severe impacts on Li-ion batteries by …
Compressed air energy storage (CAES), another technology, exhibits a high energy density but is dependent on specific geological features as well, and it tends to have lower efficiency [27, 30]. Flywheels, on the other hand, are characterized by high power density but relatively lower energy density compared to other ESS technologies.
