When the battery is the main source of energy for systems in HEVs/EVs, it is essential to have information about its charging and discharging cycles. Current sensors are the main source of information for charging and discharging cycle information by reporting the status of battery SOH to the battery management system.
Three-dimensional research directions in fault diagnosis of lithium-ion battery energy storage station. In summary, the aforementioned literature deeply investigates fault diagnosis methods, transmission systems, and multi-scenario-oriented public datasets for energy storage systems.
One way to figure out the battery management system's monitoring parameters like state of charge (SoC), state of health (SoH), remaining useful life (RUL), state of function (SoF), state of performance (SoP), state of energy (SoE), state of safety (SoS), and state of temperature (SoT) as shown in Fig. 11 . Fig. 11.
To optimize and sustain the consistent performance of the battery, it is imperative to prioritise the equalization of voltage and charge across battery cells . The control of battery equalizer may be classified into two main categories: active charge equalization controllers and passive charge equalization controllers, as seen in Fig. 21.
Current sensors are the main source of information for charging and discharging cycle information by reporting the status of battery SOH to the battery management system. They may be located onboard or externally. With the increase of battery capacities in HEVs/EVs, the requirements on higher current ranges are increasing.
Nonetheless, when we need to characterize the battery pack function state under exact constraint circumstances, the state of function is the best option. The Fuzzy Logic Control Algorithm (FLCA) is the most recent approach for estimating SoF. The FLCA, an intellectual control method used to estimate the SOF, has an essence.
