What's the function for a combiner box in lithium battery pack system?
Firstly, the combiner box plays a crucial role in the testing of energy storage batteries. The combiner box can connect multiple battery cells or modules together to form a battery pack, making it convenient for unified charging and discharging tests. Through the combiner box, uniform charging and discharging of the battery pack can be achieved, avoiding overcharging or over discharging of individual batteries, thereby protecting the batteries and extending their service life.
Secondly, connecting the combiner box can also facilitate monitoring of the battery pack. The combiner box is usually equipped with sensors for current, voltage, etc., which can monitor the working status of the battery pack in real time, including parameters such as charging and discharging current, voltage, temperature, etc. These parameters are important basis for evaluating battery performance and safety. By monitoring these parameters, potential problems can be identified in a timely manner, and corresponding measures can be taken to ensure the stable operation of the battery pack.
If the energy storage battery test is not connected to the combiner box, it may cause a series of problems.
Firstly, there may be uneven charging and discharging between individual batteries, leading to overcharging or over discharging of some batteries, which affects their performance and lifespan.
Secondly, without monitoring of the combiner box, it is difficult to detect battery pack problems in a timely manner. Once a fault occurs, it may cause serious consequences and even lead to safety accidents.
Therefore, connecting the combiner box is crucial for testing energy storage batteries. By connecting the combiner box, the uniform charging and discharging of the battery pack and monitoring can be ensured, improving the accuracy and safety of testing. At the same time, connecting the combiner box can also improve testing efficiency and facilitate unified management and maintenance of the battery pack.
When connecting the combiner box, the following points should be noted. Firstly, select the appropriate model and specifications of the combiner box to ensure it matches the battery pack. Secondly, correctly connect the cables and sensors of the combiner box to ensure the accuracy and stability of data transmission. Finally, regularly inspect and maintain the combiner box to ensure its proper functioning.
In short, energy storage battery testing requires connecting to a combiner box to ensure uniform charging and discharging of the battery pack and monitoring. By connecting the combiner box, the accuracy and safety of testing can be improved, the service life of the battery can be extended, and the stable operation of the energy system can be ensured.
In what condtion I need to add a combiner box?
It depends on your working current.
5KWH battery pack, if the inverter power is 10KW or more, we suggest to add a combiner box.
10KWH battery pack, if the inverter power is 12KW or more, we suggest to add a combiner box.
