– Passive balancing is a common method used in battery management system.
– It relies on resistors to dissipate excess energy from overcharged cells as heat.
– Passive balancing is cost-effective and simple but may not be as efficient as active balancing.
– Active balancing uses electronic components like switches and capacitors to redistribute energy.
– It’s more efficient and can balance cells faster and with greater precision than passive methods.
– Active balancing is often preferred in high-performance or high-capacity battery systems but can be more expensive.
– Integrated BMS is built directly into the battery pack or device it manages.
– It’s often used in applications like electric vehicles (EVs) and consumer electronics.
– Integrated BMS can provide a compact and seamless solution, but it may be less flexible for custom setups.
– Standalone BMS is a separate unit that can be added to existing battery systems.
– It offers flexibility and compatibility with a wide range of battery configurations.
– Standalone BMS is commonly used in renewable energy systems, where battery packs may vary in size and type.
– Wired BMS systems use physical cables to transmit data and commands.
– They are known for their reliability and can handle high data transfer rates.
– Wired battery management system is often used in critical applications where data accuracy is paramount, such as medical devices or aerospace.
– Wireless BMS systems use radio frequency (RF) or other wireless technologies to transmit data.
– They offer flexibility in installation and are suitable for applications where wiring is impractical.
– Wireless battery management system can be found in IoT (Internet of Things) and remote monitoring setups.
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.

– Restore paste to 25±2°C before use.
– Clean both sides of steel mesh every 4 hours.
– Optically 2D(or 3D) measure solder paste after PCB printing.
– Detect micron-level defects to ensure quality.
Mount electronic components based on BOM list.
– Detect welding defects using optical technology.
– Check component patch quality.
– Heat PCB and attached components to achieve welding.
– Controlled temperature prevents oxidation and cost control.
– Recheck welding quality.
– Perform repairs if needed.
– Remove tested PCBAs with mounted components.
– Conduct first piece confirmation, appearance, BGA, and QA inspections.
– Package and store after confirmation.
Different battery chemistries (e.g., lithium-ion, lead-acid, nickel-cadmium) have unique characteristics and require specific BMS designs. Consider the chemistry of your batteries and tailor the battery management system accordingly.
Voltage and Capacity:
Determine the voltage and capacity requirements of your battery pack. The battery management system should be designed to handle the specific voltage range and capacity of the batteries.
Depending on your application, batteries can be connected in series, parallel, or a combination of both. Ensure the battery management system can monitor and manage cells in the chosen configuration.
Safety is paramount. Implement safeguards to prevent overcharging, over-discharging, short circuits, and thermal runaway. Include temperature sensors and other safety features to protect the batteries and surroundings.
If your battery pack includes multiple cells, the battery management system should have a balancing function to ensure that all cells remain at similar voltage levels, which maximizes the lifespan of the pack.
Consider how the battery management system communicates with external systems or users. This might involve data logging, remote monitoring, or integration with other control systems.
State of Charge (SOC) and State of Health (SOH) Estimation:
Implement algorithms for accurate SOC and SOH estimation, which are critical for understanding the battery’s current capacity and predicting its remaining lifespan.
Monitor individual cell voltages, temperatures, and internal resistance. This information helps identify weak or failing cells within the battery pack.
Consider how users will interact with the battery management system, whether through a graphical user interface (GUI) or other means.
Redundancy and Fail-Safe Design:
Ensure redundancy in critical components and design the battery management system with fail-safe mechanisms to minimize the risk of system failure.
Consider the operating environment, including temperature extremes, humidity, and exposure to shock or vibration. Choose components that can withstand these conditions.
If your application may require future expansion or changes in battery configuration, design the battery management system with scalability in mind.
Comply with relevant safety and industry standards (e.g., UL, IEC) and consider any specific regulations that apply to your application or industry.
Cost and Budget:
Balance the desired features with the available budget. Customizing a battery management system can be expensive, so prioritize essential functions and safety.
Testing and Validation:
Rigorous testing and validation are crucial to ensure the BMS functions as intended and meets safety and performance requirements.
Firmware and Software:
Develop or customize the firmware and software that control the battery management system, ensuring it aligns with your specific requirements.
Plan for maintenance and servicing. Ensure that the battery management system can be accessed and repaired if necessary without compromising safety.
Accurate current sensing is essential for monitoring the charge and discharge rates of the battery. Use appropriate current sensors to measure these parameters.
