What is battery management system (BMS)?

Battery Management System (BMS) is the “intelligent manager” of modern battery packs, widely used in fields such as electric vehicles, energy storage stations, and consumer electronics.

Why do lithium batteries need a BMS?

The BMS prevents your lithium battery’s voltage from going too high (causing overheating and gas release) or too low (leading to permanent damage). Damage occurs if you overcharge (cell voltage gets too high) or over-discharge (cell voltage gets too low) a lithium-ion battery cell. Overcharging occurs when recharging exceeds a battery’s safe range.

How do I integrate a BMS into a power system?

There are two main ways to integrate a BMS into a power system: Built directly into the battery casing. Provides seamless, real-time monitoring of individual cells. Saves space and eliminates the need for extra wiring. Requires no additional installation — simply drop in and use.

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.
