Get a quote6 FAQs about [The most common equalization method for lithium battery packs]
Do battery pack equalization strategies have a systematic review and classification?
After a thorough literature survey, it was found that there are many battery pack equalization strategies developed, but the systematic review and classification are missing. Some studies simply classify the equalization strategies based on the equalization variable, such as voltage, SOC, and capacity.
How a battery equalization circuit works?
Literature proposed an active equalization circuit with inductors and capacitors in series, which can achieve equalization energy transfer from battery to battery pack and battery module to battery pack. But the number of switch tubes in the circuit increases more and more with the number of batteries and the energy loss increases.
What is battery capacity based equalization?
The purpose of battery capacity-based equalization is to control the maximum usable capacity of the battery group to converge, and the battery capacity can intuitively reflect the inconsistency of the battery group.
Does the equalization strategy reduce the inconsistency of a battery group?
The equalization strategy designed in this article promotes the equilibrium speed and equalization efficiency, and effectively decreases the inconsistency of the equalized battery group. Finally, the experiments are conducted by Matlab/Simulink platform.
Why are battery pack equalization variables difficult to measure?
Measuring and estimating battery pack equalization variables have many problems, such as accuracy and computational complexity. It is difficult to ensure the accuracy and reliability of battery voltage, temperature, and current measurements due to multi-physical field interference in the operating environments of EMSs.
Can a battery and equalization circuit be optimized for energy consumption?
Therefore, by considering the energy efficiency of the battery and equalization circuit, optimization for energy consumption can reduce equalization energy consumption, improve energy throughput and reduce cost. However, it is difficult to accurately obtain the current of each equalizing circuit.
