Abstract
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. 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. In order to solve this problem, Battery Management System (BMS), a technology specially used to supervise battery packs, is used for the management of battery packs. The oversight that a BMS provides usually includes: Monitoring the battery, Providing battery protection, Estimating the battery’s operational state, Continually optimizing battery performance, Reporting operational status to external devices. 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. This chapter classifies the topology of BMS and investigates the hardware and software architecture of BMS. The main functions of BMS are introduced.
