The role of BMS in new energy storage systems

With the increasing global concern about environmental issues, new industries such as new energy storage systems are gradually emerging. In the new energy storage system, the battery as an important part of the whole system, its performance is related to the life of the whole system, safety and other aspects. Therefore, the battery management system (BMS), as the "brain" of the battery, monitors and controls the operating status of the battery in real time to ensure safe and reliable operation of the battery. This paper will introduce the role of BMS in new energy storage system in detail, and on this basis, will introduce the advantages of BMS and its importance.

Basic functions of BMS

The BMS mainly has the following basic functions:

Battery status monitoring

The BMS can monitor the battery's power, temperature, voltage, current and other parameters in real time. After collecting data through sensors, data analysis and processing are performed in order to understand the state and performance of the battery. In addition to the above parameters, the BMS can also monitor the SOC (State of Charge) of the battery, so as to more accurately grasp the state and performance of the battery.

Battery Protection

The BMS can protect the battery, for example, if the battery is overcharged, overdischarged or overtempered, the BMS will automatically cut off the connection between the battery and the load to prevent the battery from overheating, short circuit and other dangerous situations. In addition, BMS can also equalize the battery so that each individual cell of the battery has the same power level, thus prolonging the service life of the battery.

Troubleshooting

BMS can diagnose the battery failure, such as single cell battery failure, battery internal resistance increase, etc. BMS will prompt the user through the form of alarm light or fault code, and take timely measures to repair. Fault diagnosis is a very important function of BMS, which can help users understand the status of the battery in time, so that timely maintenance measures can be taken to avoid bigger problems.

Balance charging

The BMS is able to balance charge the battery, which means that each individual cell of the battery is monitored and controlled during charging to ensure that each cell has the same charge level and extend the battery life. Compared with the normal charging method, balanced charging can charge more evenly, avoiding overcharging and over discharging of the battery, thus extending the battery life.

Advantages of BMS

The BMS, as the core component of the battery management system, has the following advantages:

Increase battery life

The BMS can monitor and control the battery in real time to ensure safe and reliable operation of the battery, thus extending its service life.

Improving the performance of new energy storage systems

BMS can accurately manage the battery, thus improving the performance of the new energy storage system and providing a better experience for users.

Ensure safe and reliable operation of the battery

The BMS can protect the battery, for example, if the battery is overcharged, overdischarged or overtempered, the BMS will automatically cut off the connection between the battery and the load to prevent the battery from overheating, short circuit and other dangerous situations.

Importance of BMS

The importance of BMS in the new energy storage system is self-evident. First, BMS can ensure safe and reliable operation of the battery, avoiding the occurrence of dangerous situations such as battery overcharge, overdischarge and overtemperature; second, BMS can achieve accurate management of the battery, reducing the loss of battery life and extending the service life of the battery; finally, BMS can also improve the performance of the new energy storage system and provide a better experience for users.

Concluding remarks

As the core component of battery management system of new energy storage system, BMS has an important role in ensuring battery safety, improving battery performance and extending battery life. In the future, with the continuous development of the new energy storage system industry, the BMS will also continue to improve and enhance to provide better services for users.
