Battery Management System Essentials

This course covers the comprehensive understanding of Battery Management Systems (BMS). It starts with the exploration of BMS measurements, emphasizing the importance of sensing voltage, current, temperature, and isolation in a battery pack. For instance, the course explains how an Analog to Digital Converter (ADC) is used to measure voltage by converting analog signals into digital values. The course then moves on to the protection and management of battery packs, discussing the undesirable events that necessitate protection schemes and how BMS uses sensors and algorithms to detect and manage these conditions. The course also delves into the various components of a BMS, such as the pre-charge circuit and Management Control Unit (MCU), and their roles in managing the battery pack. Lastly, the course discusses the design and testing of BMS, highlighting the importance of cell balancing and the role of the Insulation Monitoring Device (IMD).
