What is battery management system (BMS)?
Battery packs are a key component in EVs. Modern lithium-ion battery cells are characterized by low self-discharge current, high power density, and durability. At the same time, the battery management system (BMS) plays a pivotal role in ensuring high efficiency and durability of battery cells and packs.
What is a BMS for lithium-ion batteries?
A BMS for lithium-ion batteries acts as the "brain" of the battery pack, continuously monitoring, protecting, and optimizing performance to ensure safe operation and maximum lifespan. Understanding how BMS technology works is essential for anyone involved with lithium-ion applications.
Why is a BMS important in a battery system?
Hence, timely and accurate fault detection and response by the BMS are essential to prevent such dangerous situations or battery failures. An onboard battery system typically comprises lithium-ion batteries, BMS, sensors, connectors, data acquisition sensors, thermal management systems, cloud connectivity, and so on.
How accurate is a battery management system (BMS)?
The BMS employs multiple algorithms including coulomb counting, voltage-based estimation, and advanced techniques like Kalman filtering to provide precise charge level information. SOC accuracy directly impacts user experience and battery protection. Overestimation can lead to over-discharge, while underestimation reduces usable capacity.
BMS technology varies in complexity and performance: • Simple passive regulators achieve balancing across batteries or cells by bypassing the charging current when the cell's voltage reaches a certain level. The cell voltage is a poor indicator of the cell's SoC (and for certain lithium chemistries, such as, it is no indicator at all), thus, making cell voltag.
