What Is Battery Management System (BMS) ?

What is battery management system?

A battery management system provides powerful tools to monitor the operating status of a battery pack, and to improve the battery's lifespan, reliability, safety, as well as charging and discharging performance.

The battery management system uses specialized computers and sensors to make the battery more "intelligent", and provides real-time information and data collection on its performance.

What does battery management system do?

In summary, the battery management system is responsible for analyzing real-time measurements of a battery, adjusting charging/discharging parameters accordingly, and relaying essential information to end-users. These measurements include battery voltage, state of charge (SOC), state of health (SOH), temperature, and other critical metrics. An easy-to-read screen displays important information like charging time. As a vital piece of technology for the maintenance and efficient use of batteries, a reliable battery management system supplier is ideal for ensuring that monitoring and control systems remain high-quality and up-to-date.

When and where to use battery management system?

A battery management system (BMS) brings many benefits to battery operations.

For these reasons, battery management systems (BMS) are often used in off-grid applications and battery backup applications, including generators, power facilities, telecommunications, hospitals, data centers, and more.

However, for lithium-ion batteries, a battery management system (BMS) has some advantages, but reducing the likelihood of the battery catching fire or exploding is an absolute safety requirement. This is because lithium-ion batteries have the highest power density among similar products, and overcharging a low-capacity battery can lead to thermal runaway and combustion.

Therefore, in lithium-ion batteries, a battery management system (BMS) ensures that the battery operates within an ideal operating window (including temperature, current, voltage, maximum charge, current limit, etc.). A battery management system (BMS) can also help ensure correct voltage balance for the battery cells.

The key benefits of battery management system for batteries

Without a battery management system (BMS), battery operators typically rely solely on routine maintenance measures to determine impending battery issues and when to repair or replace the battery.

However, with the addition of a battery condition monitoring system, operators can capture vital operational parameters such as voltage, current, ambient temperature, and electrolyte level of the battery/cell. This supplementary data enhances the routine maintenance measures and ensures that any potential issues can be detected and resolved before they cause harmful effects. Therefore, incorporating a reliable battery condition monitoring system can be invaluable for safeguarding the longevity and proper function of batteries in various applications.

This data is automatically logged and can be used for predictive maintenance and more accurate estimates of operating time.
