What is BMS for lithium-ion battery?
Battery Management System
A BMS (Battery Management System) is essential in a Lithium-Ion battery system. This device manages a real-time control of each battery cell, communicates with external devices, manages SOC calculation, measures temperature and voltage, etc.
Why BMS is required for lithium-ion battery?
The lithium-ion batteries can be used only in specified conditions, and therefore battery management system (BMS) is necessary in order to monitor battery state and ensure safety of operation. Moreover, typical functions of BMS have been described with special attention to state of charge (SoC) estimation.
How does a lithium BMS work?
The Orion Battery Management System (BMS) performs three primary functions: It does this by constantly monitoring every cell in the battery pack and calculating exactly how much current can safely go in (source, charge) and come out (load, discharge) of the battery pack without damaging it.
What is PCM protection?
PCM or PCB ( protection circuit module or board ) is “heart” of Li-Ion battery pack. It will protect Li-Ion battery pack from overcharging, over-discharging and over-drain, therefore it is must have to avoid Li-Ion battery pack from exploding, firing and damage.
Why are BMS and PCB needed For LiPo battery?
So at least PCB/PCM must be used for lithium ion battery with basic protections, however for bigger lithium battery packs, it involves lots of battery cells, the unbalance of cells will also cause problems, such as shorter cycle life, low voltage, so on base of above mentioned four protections, balance function is added to make a basic BMS.
How does BMS work on a Li ion battery?
Simple analog technology, just able to detect that some cell’s voltage is too low or too high, but unable to report which one. Able to balance the battery.

What’s the difference between a BMS and a PCB?
BMS is battery management system, always for big battery packs, PCB or PCM is protection circuit board, usually for small battery, typical use is for digital batteries, like mobile phone battery,camera battery,mp3 player battery,GPS batteries,heated clothing batteries Select Language: Service Hotline:86-755-29184180
Why do you need regulator in Li ion battery?
Regulators (also called “equalizers” or “balancers”) are sometimes used in Li-Ion packs as a simple protection against overcharging. A regulator is required across each cell. A regulator performs balancing during charging by bypassing charging current from the fully charged cells, so that other cells in the battery can finish charging.
