When it comes to designing a battery pack with high power density and multiple features, engineers may consider a modular approach in order to reduce development time and facilitate testing. In an article written by Anvin Joe Manadan (Sr. Electrical Engineer at Inventus Power) for Battery Technology, learn about the benefits of modular design and the steps you need to take when building lithium-ion (Li-ion) battery packs.
Modular battery pack design can be complex, but once you break down the steps it's quite achievable. In fact, most battery packs that require higher power density are composed of several modules all working together to create a fully functioning battery system. When the individual modules of a battery pack, like cells, fuel gauges, protective devices, and more, are designed separately, it decreases development time and makes testing more efficient. In this article, we'll explain the advantages and challenges of the modular approach to designing battery packs.
