If you are looking to build safe-high performance battery packs, then you are going to need to know how to choose a BMS for lithium batteries. The primary job of a BMS is to prevent overloading the battery cells. So, for this to be effective, the maximum rating on the BMS should be greater than the maximum amperage rating of the battery.
The key function of a lithium battery BMS is cell balancing. What is a conventional BMS and how is the Flash Balancing System different?
The choice of a BMS depends mainly on the application in which the battery or lithium battery pack is integrated. Indeed, the electronic card selected for the lithium battery pack of an embedded solutions (e.g. electric vehicle) will not be the same as the one intended for the management of a battery of a stationary application.
But the conditions of use are stricter. Therefore, nearly all lithium batteries on the market need to design a lithium battery management system. to ensure proper charging and discharging for long-term, reliable operation. A well-designed BMS, designed to be integrated into the battery pack design, enables monitoring of the entire battery pack.
Choosing the best BMS for lithium and LiFePO4 batteries can be a challenge if you are not familiar with all the terms and with so many brands on the market that all claim to be the best. JK BMS, JBD Smart BMS, and DALY BMS are the best BMS makers out there, but this article reveals that there are levels to that, too.
The choice of a Smart BMS is therefore recommended to ensure the full safety of a lithium battery or battery pack. The choice of a BMS depends mainly on the application in which the battery or lithium battery pack is integrated.
