Certification requirements from various government regulations where costs and penalties are paramount if inadequate functional safety measures are in place.Application of the battery and any safety, lifespan, and warranty concerns.The costs, complexity, and size of the battery pack.The technology design scope and implemented features generally correlate with: The BMS certainly has a challenging job description, and its overall complexity and oversight outreach may span many disciplines such as electrical, digital, control, thermal, and hydraulic.īattery management systems do not have a fixed or unique set of criteria that must be adopted. While they perform superbly, they can be rather unforgiving if operated outside a generally tight safe operating area (SOA), with outcomes ranging from compromising the battery performance to outright dangerous consequences. Lithium-ion rechargeable cells have the highest energy density and are the standard choice for battery packs for many consumer products, from laptops to electric vehicles. Here, the term “battery” implies the entire pack however, the monitoring and control functions are specifically applied to individual cells, or groups of cells called modules in the overall battery pack assembly.
