All You Need to Know About BMS Systems

bms 2

The Battery Management System (BMS) plays a vital role in optimizing lithium-ion battery pack performance. BMS monitors individual cell voltage, prevents overcharging, and ensures thermal management, all crucial for lithium battery health.
With cell balancing and state of charge(SOC) monitoring, BMS maximizes efficiency and safety, a key factor in preventing issues like thermal runaway.
In the world of lithium batteries, BMS is essential for achieving peak performance and longevity.

Why do lithium-ion batteries need protection?

  • Lithium-ion batteries are particularly sensitive to the risks associated with over-charge and over-discharge.
Battery Material Charging Cut-off Voltage Discharge Cut-off Voltage
Lithium Iron Phosphate (LiFePO) ≤3.85V ≥2.5V
Nickel, Cobalt, Manganese (NCM) ≤4.2V ≥2.7V
Lithium Manganate (LMO) ≤4.2V ≥2.7V

Lithium-ion batteries are more likely to be overcharged and over-discharged when used in battery packs, the root cause of which lies in the consistency difference of the battery cells. 
If the charging and discharging process is not properly controlled, it will be further increased, resulting in overcharging and over-discharging of some battery cells.

What makes up a Battery Management System?

Temperature Sensor Interface: Temperature sensors are used to monitor the temperature of the battery pack. This information is crucial for ensuring safe operation and preventing overheating.

Communication Interface: The BMS often includes communication interfaces like UART, CAN bus, I2C, or SPI. These interfaces allow the BMS to communicate with external devices, such as battery chargers, host systems, or monitoring tools.

MCU (Microcontroller Unit): The MCU is the brain of the BMS, responsible for data processing, decision-making, and overall control of the system. It collects data from various sensors and communicates with other components to ensure the safe and efficient operation of the battery.

B- (Battery Minus): This terminal is part of the battery pack and is connected to the negative terminal of the battery cells. It provides a reference point for measuring cell voltages and is used for balancing cells.

P- (Pack Minus): P- is the negative terminal of the entire battery pack, including all the cells in the pack. It serves as the main negative connection point for the entire pack.

Power MOSFET (MOS Tube): Power MOSFETs are used for controlling the charging and discharging of the battery cells. They act as switches to regulate the flow of current and protect against overcharging or over-discharging.

Battery Collecting Cable: These cables connect the AFE to the battery cells for voltage and current sensing. They are essential for collecting data from individual cells.

AFE (Analog Front End): The AFE is a critical component that interfaces with the battery cells. It measures cell voltages and currents accurately and feeds this data to the MCU for processing. It also plays a role in balancing cells.

The Topologies of Battery Management System

BMS topologies


It has the advantages of low cost, compact structure, and high reliability.
It is commonly used in scenarios where the capacity is low, the total voltage is low, and the battery system volume is small. Such as power tools, intelligent robots (handling robots, assist robots), IOT smart home (sweeping robots, electric vacuum cleaners), electric forklifts, electric low-speed vehicles (electric bicycles, electric motorcycles, electric sightseeing vehicles, electric patrol cars, electric golf carts, etc.), light hybrid vehicles.


Electric vehicles (pure electric, plug-in hybrid), electric ships, etc.


Container energy storage system (EMS), energy storage power station. etc.

Four communication protocols commonly used in BMS (Battery Management System)

  • CAN BUS is a robust and reliable communication protocol widely used in BMS. It enables real-time data exchange between components, ensuring seamless coordination within the battery system.
  • CAN BUS is known for its high data transmission rate, fault tolerance, and suitability for complex BMS applications.
uart communication protocol
  • UART is a fundamental communication protocol in BMS that allows for serial data transmission. It is known for its simplicity and ease of implementation.
  • UART is often used for basic communication tasks within the BMS, offering a straightforward way to exchange data between components.
rs485 communication protocol
  • RS485 is a widely adopted communication standard in BMS for applications that require longer communication distances and noise immunity.
  • It’s well-suited for multi-node systems and offers differential signaling, ensuring reliable data transmission even in electrically noisy environments.
tcp (transmission control protocol)

TCP (Transmission Control Protocol)

  • TCP is a network communication protocol often used in BMS for remote monitoring and control. It enables secure and orderly data transfer over the internet or local networks.
  • TCP ensures data integrity and reliability, making it ideal for applications where remote access to BMS data is essential.
