Balancing lithium batteries in parallel involves measuring each battery's voltage before connection, ensuring they're within an acceptable range of each other, and then connecting all positive and negative terminals together. What Does It Mean For Lithium Batteries To Be Balanced?
Balancing lithium battery packs, like individual cells, involves ensuring that all batteries within a system maintain the same state of charge. This process is essential when multiple battery packs are used together in series or parallel configurations.
1. Introduction 2. Establishment and Verification of Battery Pack Model 3. Influence of Individual Cell Parameter Difference on Battery Pack Performance 4. Conclusions Lithium-ion power batteries are used in groups of series–parallel configurations.
According to the parallel principle, the current of the main circuit is equal to the sum of the currents of the parallel branches. Therefore, a parallel lithium battery pack with “n” parallel batteries achieves the same charging efficiency as a single battery, with the charging current being the sum of the individual battery currents.
By connecting two or more lithium batteries with the same voltage in parallel, the resulting battery pack retains the same nominal voltage but boasts a higher Ah capacity. For example, connecting two 12V 10Ah batteries in parallel method creates a 12V 20Ah battery.
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.
