To meet the power and energy requirements of the specific applications, lithium-ion battery cells often need to be connected in series to boost voltage and in parallel to add capacity . However, as cell performance varies from one to another [2, 3], imbalances occur in both series and parallel connections.
To meet practical usage requirements, lithium-ion batteries usually need to form a battery pack. However, due to production deviations and different usage environments, there are inconsistencies between batteries within the battery pack. This makes it challenging to estimate the state of charge (SOC) of the battery pack accurately.
The nominal voltage is the average voltage during a discharge. Normally, the cell voltage for lithium-ion batteries is around three to four volts (V). Several cells, therefore, are needed to form a pack to achieve the voltage required for a certain application, for instance, 48 V.
For components in series, the current through each is equal and the voltage drops off. In a simple model, the total capacity of a battery pack with cells in series and parallel is the complement to this.
The cell voltage is determined by its two electrodes: the negative (anode) and the positive electrode (cathode). The nominal voltage is the average voltage during a discharge. Normally, the cell voltage for lithium-ion batteries is around three to four volts (V).
When several lithium cells are connected in series, it is the variation between series sections that requires balancing to be used. The problem with leakage and charge efficiency is that differences in these have a cummulative effect, and battery imbalance grows with each charge/discharge cycle.
