Parallel Connections

In a parallel connection, the positive terminals of all battery modules are connected together, as are the negative terminals. This method increases the total capacity (Ah) of the battery pack while maintaining the same voltage as a single module. For example, if each battery module has a capacity of 100Ah, connecting three modules in parallel results in a total capacity of 300Ah at the same voltage.

Advantages of Parallel Connections:

• Increased Capacity: Suitable for applications demanding higher energy storage.
• Enhanced Fault Tolerance: One module’s failure does not necessarily incapacitate the entire system.

Disadvantages of Parallel Connections:

• Higher Complexity: Requires more connections and careful management of charge/discharge rates.
• Potential for Imbalance: Modules must be carefully matched to avoid uneven charging.

Series-Parallel Connections

Series-parallel connections combine the features of both series and parallel configurations to offer both increased voltage and capacity. In this arrangement, modules are grouped in series to achieve a desired voltage, and then these groups are connected in parallel to enhance capacity. This method provides a balance between voltage and capacity, making it suitable for many high-performance applications.

Advantages of Series-Parallel Connections:

• Versatility: Allows for flexible voltage and capacity configurations.
• Balanced Performance: Provides a balance between high voltage and high capacity.
