There are many types of lithium-ion battery equalization circuits, the most common of which is the passive equalization circuit. The active equalization circuit is better than the passive equalization circuit in terms of performance, but it is very complex and expensive .
Due to production and manufacturing differences, the consistency of many lithium-ion batteries used in series and parallel will deteriorate, so battery equalization techniques are needed to maximize the available battery capacity and ensure safe battery pack operation [1–3].
In passive cell equalizer, passive elements, such as resistors, have been used in developing the equalizer to equalize the entire cell voltage in a battery pack. This equalizer removes the excess energy from high-voltage cells through the shunt-connected resistor until the voltage is equal to low-voltage cells or voltage reference.
The entire battery pack is divided into several modules to improve the equalization speed . This equalizer introduces intra- and inter-module equalization. In intra-module equalization, all the cells in a module are equalized as in a conventional equalizer. This equalizer allows module-to-module equalization.
The active equalization circuit is better than the passive equalization circuit in terms of performance, but it is very complex and expensive . However, an equalization circuit that uses an external power source to continue equalizing and charging a battery with a low SOC is widely used.
Recent research trend of equalizers for battery cells equalization are explained. Four distinctive battery cells voltage equalizer circuits are simulated utilizing MATLAB/Simulink and compared. Recently, the use of electric batteries has reached great heights due to the invention of electric vehicles (EVs).
