Lithium-ion battery BMS system

What is a lithium-ion battery management system (BMS)?

Figure 1: Why Lithium-ion Batteries? The battery management system (BMS) is an intricate electronic set-up designed to oversee and regulate rechargeable batteries, specifically lithium-ion batteries.

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 ion batteries need a BMS?

The BMS helps batteries last longer too. It balances cells so weaker ones don’t limit the pack’s performance or get damaged faster. By stopping deep discharge and overcharge, it protects against common causes of permanent capacity loss. Lithium-ion batteries need precise control.

How does a battery management system improve the performance of lithium-ion batteries?

Now, let's delve into how a BMS enhances the performance of lithium-ion batteries. The battery management system (BMS) maintains continuous surveillance of the battery's status, encompassing critical parameters such as voltage, current, temperature, and state of charge (SOC).
