1. Learning About Lithium Batteries

The commonly used types of lithium batteries are lithium-ion batteries, lithium polymer batteries, and lithium iron phosphate batteries. They differ in terms of electrolyte, battery size, and battery performance.

  1. Lithium-ion battery: Lithium-ion batteries use liquid electrolyte, with the positive electrode material typically being an oxide. They offer high energy density and operating voltage, and are widely used in mobile devices, power tools, electric vehicles, and more.
  1. Lithium polymer battery: Lithium polymer batteries use a polymer gel as the electrolyte, with the positive and negative electrode materials typically being oxides. They offer high energy density and smaller size, making them suitable for thin electronic products and mobile devices.
  1. Lithium iron phosphate battery (LiFePO4 battery): Lithium iron phosphate batteries use lithium iron phosphate as the positive electrode material. They offer high safety and cycle life, and are widely used in electric vehicles, energy storage systems, and more.
2. What is BMS ?

BMS stands for Battery Management System.

It is an electronic system used to monitor, control, and protect the performance and safety of a battery pack.

The main functions of a BMS include the following:

  1. Battery parameter monitoring

  2. Battery protection and safety control

  3. Battery balancing control

  4. Communication and data management

3. Why is BMS required for lithium battery packs ?

 The BMS is an important component of a lithium battery pack, providing functions such as battery protection, balancing, and monitoring, ensuring the safe operation of the battery pack, and extending the battery’s service life.

Lithium battery packs without a BMS are prone to issues like overcharging, overdischarging, cell imbalance, and safety risks. These problems can significantly reduce the performance, safety, and lifespan of the battery pack.

4. What types of BMS are there ?

The application scenarios of BMS in battery packs can be divided into the following types:

  1. Electric Tools BMS
  2. Electric Vehicles BMS
  3. High Power BMS
  4. Energy Storage BMS
  5. Car Start BMS
  6. other

BMS can be classified into the following types based on their functions:

  1. Standard BMS (Hardware BMS)
  2. Smart BMS
5. What difference between Smart BMS and Hardware BMS ?

Smart BMS is equipped with advanced features such as data monitoring, communication interfaces, and intelligent algorithms. These capabilities allow it to gather real-time data, analyze battery performance, and communicate with external systems or applications. 

Hardware BMS typically focuses on basic functions like cell voltage monitoring, temperature monitoring, and protection mechanisms. 

6. What is Lithium Battery Balancing Board ?

Lithium battery balancing boards are primarily used to balance the charge status of individual cells within a battery pack, ensuring that each cell reaches the same charge level to improve overall performance and lifespan of the battery pack.

Capacitive balancing and inductive balancing are two common methods of battery balancing.

Capacitive balancing involves connecting capacitors to each individual cell and balancing the charge within the battery pack through charging and discharging. Capacitive balancing modules have an automatic balancing architecture, allowing the entire battery pack to actively participate in energy transfer for fast and high-current balancing of voltage differences between cells.

Inductive balancing adjusts the current between battery cells using inductors and resistors to achieve balance. Resistors adjust the voltage difference through heat dissipation. Inductive balancing modules trigger balancing when the voltage difference between adjacent cells exceeds 0.1V and stop working when the voltage difference between adjacent cells is within 0.03V.
