Cell Design

Cells are the main component of a battery pack. They provide the primary power source. Cells connected in series can add the voltage of a battery pack. The voltage of a battery pack is the voltage of single cell multiplied by the series cells’ number. Battery capacity can be increased throught adding more parallel cells. The capacity of a battery pack is the capacity of the individual 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, 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.

Based on customer's requirements, CREUP can not only design and produce custom cells but also build custom multi-cell battery packs to deliver the necessary power for the customer's special applications.
