What is a battery management system (BMS)?

Like lead-acid batteries, lithium batteries can be permanently damaged by overcharging, deep discharging, or extreme temperatures. That’s where the Battery Management System (BMS) comes in. Often called the brain of the battery, the BMS ensures your batteries operate safely, efficiently, and for as long as possible. In this guide, we’ll cover:

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 does a balanced battery management system work?

A balanced system prevents degradation and maximizes capacity across the battery pack. In this piece, we’ll learn about how BMS technology works with vehicle systems like thermal management and charging infrastructure. On top of that, we’ll get into how predictive analytics and machine learning reshape the scene of battery management systems.

What makes a good battery management system?

They need to handle new challenges while controlling complex battery systems more precisely. A good battery management system (BMS) needs hardware components that work together to monitor, protect, and optimize battery performance. These components act as the system’s eyes and ears.
