There are various types of energy storage, among which electrochemical energy storage is a key energy storage method. The electrochemical energy storage system is mainly composed of energy storage batteries, inverters, BMS battery management systems and other electrical equipment. The energy storage BMS system is responsible for communicating with the grid, controlling key parameters such as harmonics and frequency, and realizing information interaction between the PCS and the monitoring system. Then, the PCS controller obtains the status information of the battery pack through the CAN interface and BMS communication, and is responsible for monitoring the working status of each single battery, uploading battery related information and status through communication, preventing the battery from overcharging and over-discharging, and playing an effective role. Protective effects.
The energy storage monitoring system is responsible for the interface between the BMS battery management system and the distribution network system. It can accept dispatching instructions and help complete grid work such as battery charge and discharge control, independent off-grid system support, peak shaving, valley filling, and stable output of new energy power generation. For practical applications, BMS plays a crucial role in the whole electrochemical energy storage system.
There are a large number of battery clusters in the energy storage system, and the battery clusters have balance management and cycle management. The BMS of the energy storage system puts forward higher requirements for anti-interference.
