36. Jocher, P. ∙ Steinhardt, M. ∙ Ludwig, S. Parallel connection of cells is a fundamental configuration within large-scale battery energy storage systems. Here, Li et al. demonstrate systematic proof for the intrinsic safety of parallel configurations, providing theoretical support for the development of battery energy storage systems.
Lithium batteries can indeed be connected in parallel, and this method is commonly used to achieve higher capacity and extend the runtime of a battery system. 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.
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.
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.
Without proper monitoring, excessive current flow between batteries can result in overheating. To enhance safety, it is essential to incorporate fuses, circuit breakers, and a high-quality BMS to monitor voltage levels and prevent short circuits. How to Optimize Lithium Batteries in Parallel Connection 1. Use Identical Batteries
A Parallel BMS plays an important role in achieving safe and efficient parallel battery configurations. It continuously monitors the voltage, temperature and charging status of each battery, ensuring that the battery is balanced and protected during the charge and discharge cycle. A BMS for parallel cells performs several essential functions:
