Cell Design

Cells are the main component of packs. They provide the primary power source. Cells connected in series can add the voltage of batteries. The voltage of a battery pack is the voltage of single cell multiplied by the series cells’ number. The amp hour capacity of cells can increase by adding more parallel cells. The capacity of a battery pack is the capacity of single chain multiplied by the number of parallel chains.

For applications which require higher voltage and more capacity than a single cell can deliver, some custom battery packs are assembled with both series cells and parallel cells so that both the voltage and amp hour capacity are increased.

To design a multi-cell battery pack it is critical to first calculate the system requirements for voltage, capacity and discharging rate based on a specific cell’s parameters. The operating voltage range of an application system will determine the number of series cells required in a battery pack. A battery pack’s capacity and discharging rate will determine the number of parallel cells required.

Moreover, the cells will determine the ultimate shape and dimensions of a multi-cell pack. Arrangement of cells, circuitry, connections and terminals should be carefully considered to fit into the physical space available.

Creup can design and assemble custom multi-cell battery packs based on your requirements to deliver the necessary power for your special applications.
