There are mainly two types of filter capacitors in battery charging circuits: input filter capacitor and output filter capacitor. The AC voltage across the step-down transformer is rectified and often filtered using capacitors to obtain a regulated DC voltage through a voltage regulator chip to charge the battery.
The lithium battery pack balancing control process needs to detect the charging and discharging state of each individual battery. Figure 11 is the lithium battery balancing charging and discharging system test platform, where Figure 11 (a) is the bidirectional active balancing control integrated circuit designed in this paper.
The effective capacity of lithium-ion battery (LIB) pack is reduced by the inconsistency of individual LIB cell in terms of capacity, voltage and internal resistances.
In such cases an output capacitor can be added across the circuit to smoothen the pulses. In most of the common lead-acid battery charger circuits, capacitors are not required across the output terminals. However, charging a lithium-ion battery is slightly different and requires additional circuitry and a capacitor to protect the battery.
It is evident from the literature that SCs are complementary to lithium-ion batteries because they provide the means to charge and discharge quickly. In addition, the energy density of SC is sufficiently large compared to other capacitors. It has low maintenance and a high cycle life (Naseri et al., 2022).
For the above linear system, the Kalman filter is used to estimate the capacity of lithium battery, the Cq estimated by the linear Kalman filter is used to improve the state of charge estimation, and the Cq is estimated by the event-based linear Kalman filter.
