Battery storage power stations require complete functions to ensure efficient operation and management. First, they need strong data collection capabilities to collect important information such as voltage, current, temperature, SOC, etc.
Secondly, effective system control is crucial for battery storage power stations. This involves receiving and executing instructions to start/stop operations and power delivery. A clear communication protocol is crucial to prevent misoperation and for the system to accurately understand and execute commands.
In order to obtain greater economic benefits, energy storage can have more frequent charging and discharging operations during daily operation, which may affect the operating life of the battery and even shorten the service life. The working conditions of the energy storage system are complex and often cannot work under rated conditions.
