Cell Balancing


Cell balancing during charge and discharge gets the most from a pack. There are two primary ways to balance cells. Resistive cell balancing reduces the charge to the cell with the highest state of charge by shunting charge around it until the remaining cells catch up. Cell balancing by charge transfer uses circuitry to move charge from one cell to another. This can actually raise the effective capacity of a battery pack beyond that of its weakest cell. However, it is more complex and costly than resistive cell balancing.


But there are downfalls to cell balancing. A significantly out-of-balance cell might be a sign of an internal problem, and that might present a safety hazard if the laggard cell is continually forced into balance with others.

The team at Pro-Tech leverages the most innovative technologies to provide our customers with the most appropriate cell 

balancing design solution for their applications.


Mechanical Designs (Battery Enclosure Design)


Some battery packs are installed inside the product, and only require a shrink-wrap enclosure. In other cases, battery packs are mounted externally and may serve a mechanical function, such as a handle or base for the product. Our team has experience designing battery enclosures of all types and can help you create one that will enhance the functional design of the product while assuring that the battery passes stringent shock, vibration and environmental testing required to certify the pack for shipping.
