Uneven electrical current distribution in a parallel-connected lithium-ion battery pack can result in different degradation rates and overcurrent issues in the cells. Understanding the electrical current dynamics can enhance configuration design and battery management of parallel connections.
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:
Parallel lithium batteries have many advantages, including increased capacity, enhanced power output, and improved overall performance. When multiple batteries are connected in parallel, their individual ampere-hour (Ah) capacities add up, resulting in a higher total capacity.
When designing a lithium battery pack, engineers have two primary options: connecting individual cells directly in parallel or connecting strings of cells in parallel. Each approach has its advantages and disadvantages, and the choice depends on the specific application needs and design goals.
Understanding the electrical current dynamics can enhance configuration design and battery management of parallel connections. This paper presents an experimental investigation of the current distribution for various discharge C-rates of both parallel-connected LiFePO 4 and Li (NiCoAl)O 2 cells.
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.
