The Li-ion battery pack is made up of cells that are connected in series and parallel to meet the voltage and power requirements of the EV system.

Abstract: The lithium-ion battery has become the prevalent technology to store and serve electric power. The state of health (SOH) for a battery cell directly influences the working safety and reliability of the host system. Moreover, since the battery cells are series connected for higher terminal voltage, the cell inconsistency will also impact the performance of the whole battery
As in single-cell applications, careful control of the charging and monitoring of the cells is essential to ensure safe operation and prevent premature aging or damage to the battery. However, unlike single-cell systems, series-connected battery stacks need cell balancing.
The cells in a battery stack are “balanced” when every cell in the stack possesses the same state of charge (SoC). SoC refers to the remaining capacity of an individual cell relative to its maximum capacity as the cell charges and discharges. All battery cells must be kept within a SoC range to avoid damage or lifetime degradation.
By enabling the battery pack to work within safe and efficient factors, battery balancing strategies are used to equalize the voltages and the SOC among the cells. Numerous parameters such as the application’s particular needs, budget restrictions, and required efficiency are responsible for selection of ideal balancing techniques.
The charge levels in a multi-cell battery pack are equalized with the assistance of a latest method i.e., Active Battery Balancing. In contrast to passive balancing, where extra energy is simply depleted as heat, active balancing tries to redisperse this extra energy to other cells in the pack that need charging.
Balancing LiFePO4 batteries in series can be done by charging each battery individually with a 12V LiFePO4 compatible charger until they reach 100% state of charge and then connecting them in series with a balancer or a protective circuit module (PCM) or a battery management system (BMS) that monitors and equalizes the voltage across them.
A deep knowledge of both the chosen balancing approach and the overall system structure of the BMS is needed for combining battery balancing techniques into a BMS. It consists of accurate control strategies, careful design, strong safety mechanisms, and complete diagnostics and maintenance methods.
