Battery Cell Balancing: What to Balance and How

battery pack for particular device. The means used to perform cell balancing typically include by-passing some of the cells during charge (and sometimes during discharge) by connecting external loads parallel to the cells through controlling corresponding FETs. The typical by-pass current ranges from a few milliamps to amperes.

Active Cell Balancing in Battery Packs

There are two main methods for battery cell charge balancing: passive and active balancing. The natural method of passive balancing a string of cells in series can be used only for lead-acid and nickel-based batteries. These types of batteries can be brought into light overcharge conditions without permanent cell damage.

6 FAQs about [Balanced charging process of series battery pack]

What is the balancing algorithm for a battery pack?

The balancing algorithm of the proposed topology for the battery pack (consists of N number of serially connected cells) is divided into Z modules M1, M2 Mz. Each module may contain an equal number of k cells b1, b2 . bk. Firstly, the controller reads the voltages of all cells.

What are the different types of battery charge balancing?

Why is cell balancing important in a battery management system?

In a Battery Management System (BMS), cell balancing plays an essential role in mitigating inconsistencies of state of charge (SoCs) in lithium-ion (Li-ion) cells in a battery stack. If the cells are not properly balanced, the weakest Li-ion cell will always be the one limiting the usable capacity of battery pack.

Does electro-thermal regulation improve battery charging and balancing strategy?

Moreover, in conventional Battery Management Systems (BMS), the cell balancing, charging strategy and thermal regulation are treated separately at the expense of faster cell deterioration. Hence, this paper proposes an optimized fast charging and balancing strategy with electro-thermal regulation of LIB packs.

How many NiMH cells are in a battery pack?

For this application, the battery pack consists of 12 NiMH cells with a nominal capacity of 1700 mAh. The maximum load current of the application is 500 mA. The balancing is active during the charging period, to maintain an equal state of charge (SOC) for each cell at the end of charge.

What is cell balancing circuitry?

The balancing is active in the discharge period too, so this circuit maintains an equal discharge for each cell, both strong and weak. The energy from the strong cells is transferred into the weak cells. detailed schematic of the cell balancing circuitry in the center of the battery pack is shown in Figure 2. Figure 2.
