Highly accurate monitoring and protection functionality for Li-ion battery packs

摘要

These rechargeable battery packs are commonly used in hybrid electric vehicles or electric vehicles (HEV/EV), power tools and e-bicycles, application areas which are expected to rapidly grow over the next few years. Exactly addressing the needs of those target applications, ROHM has developed a complete multi-cell control and protection solution consisting of an analogue front end (AFE) and low power microcontroller (MCU). This chipset can handle a system using lithium-ion batteries, which requires multiple protection functions.
