When charging and discharging lithium-ion battery packs, we can take balanced measures to ensure safety and stability if we take into account the inconsistencies of each single cell. Battery balancing is a technology that extends battery life by maximizing the capacity of a battery pack with multiple batteries in series, ensuring that all its energy is available for use.
The imbalance of power between the battery cells during battery pack charging, which reduces battery charging efficiency and battery life, is thus effectively improved. In this paper, a six-cells-in-series and two-in parallel lithium battery pack is used to perform a balancing charge test.
The active cell balancing circuit of the lithium battery pack is shown in Figure 1, which is mainly composed of two parts, namely, the charging circuit and the balancing charging circuit. The circuits include a power supply, a switch circuit, a battery pack, a battery voltage measuring circuit, and a MSP430 microcontroller.
The experimental results of four Li-ion cells: (a) SoC, (b) current, (c) Switching signals, (d) SoP, and (e) terminal Voltage. This work presents a new active cell balancing algorithm for Li-ion battery cells based on DSoP and CSoP as the balancing criteria.
Battery balancing is one of the core functions of a BMS. Here are two mainly types of battery balancing: active balancing and passive balancing. The main difference between them is if they will waste battery energy or not. Active Balancing= transfers energy from high voltage cell to another cell with low voltage.
In series and parallel strings connected Lithium-ion (Li-ion) battery modules or packs, it is essential to equalise each Li-ion cell to enhance the power delivery performance and usable capacity, otherwise, it is restricted by the worst cell in the string.
Test results show that the battery cells in the battery pack are capable of quickly completing a balancing charge under different initial voltages, the maximum voltage difference is reduced to within the range of 0.05 V, and the total time required for each balancing charge is approximately 3600 s. 1.
