Problems solved by technology
[0004] However, the existing technology has certain disadvantages and hidden dangers. Since the real-time monitoring data of the BMS is very large and the processing capacity is large, when there is a safety hazard in the battery, safety control measures can only be implemented after layer upon layer upload and information distribution, which is often missed. The best time, causing unnecessary losses
In addition, the security management channel of the prior art is the same as the normal information transmission channel, and when the channel fails, security control measures cannot be implemented in time

The invention relates to the technical field of energy storage systems, in particular to a safety control method of an energy storage system, which comprises an energy storage battery pack, a batterymanagement system, an energy management system and a safety monitoring system, the energy storage battery pack, the battery management system and the energy management system are in communication connection in sequence, the energy storage battery pack, the battery management system and the energy management system are in communication connection with the safety monitoring system, the energy storage battery pack comprises a plurality of battery clusters composed of battery units, and a total positive interface and a total negative interface of each battery cluster are respectively provided withsafety units; and an energy storage inverter is connected between the battery management system and the safety monitoring system. The beneficial effects of the invention are that the independent safety monitoring system is in communication with the battery management system, the energy management system and the energy storage inverter, thereby achieving the multichannel communication capability;and when execution protection fails, protection can still be achieved through the safety unit, stability and efficiency are higher, and various abnormal conditions can be dealt with.
Description
technical field [0001] The invention relates to the technical field of energy storage systems, in particular to a safety control method for an energy storage system. Background technique [0002] At present, in the field of chemical energy storage, lithium-ion batteries have become the first choice for large-scale energy storage due to their excellent characteristics such as environmental protection and long cycle life. The management and control of a large-scale energy storage system is mainly composed of a battery management system (BMS) and an energy management system (EMS). The BMS mainly collects battery information and implements management. The EMS controls the energy storage inverter through uploaded information and issued instructions. (PCS) charge and discharge. BMS transmits battery information to EMS, EMS transmits instruction information to PCS, PCS communicates with BMS and controls battery charging and discharging. When safety protection measures need to be t...
