In , the Battery energy storage unit (BESU) is partitioned according to the State of charge (SOC), and the operating cost of the unit and the operating balance between the units are considered to achieve the objectives of improving the sustainable dispatchability and operating economy of the Battery energy storage system (BESS).
The large-scale battery energy storage system results in the generation of massive data, which brings new challenges in data storage and calculation. BMS has been unable to meet the data communication and calculation in such a scenario.
With the development of 5G , artificial intelligence (AI) and edge computing , this brings the possibility of evaluation and analysis of large-scale energy storage system inconsistency. This is reflected in the following aspects. First, 5G technology is applied to transmit massive data to the cloud with high bandwidth and low delay.
The inconsistency evaluation model for large-scale energy storage systems is established by combining edge computing. In this way, the load of terminal BMS can be greatly reduced. 6.4. Big data analysis With massive data, we can use digital twin technology in the cloud to establish a battery information traceability system for the whole life.
Consistency optimization scheme under fixed topology is validated. Future research challenges and outlooks are prospected. With the rapid development of electric vehicles and smart grids, the demand for battery energy storage systems is growing rapidly. The large-scale battery system leads to prominent inconsistency issues.
Jiang et al. analyze the influence of battery capacity, ohmic resistance and SOC consistency on energy utilization. The results show that SOC consistency has the most significant effect on energy utilization. Therefore, SOC is calculated as the feature to describe the pack consistency.

Their standard deviation are 0.00787 Ω, 0.00316 Ω and 0.0361 V, respectively. The standard deviation of R o is about 2.2 times that of OCV. Therefore, it seems unreasonable to use voltage unilaterally as a criterion for the pack consistency evaluation. In contrast, the consistency evaluation method with multi-feature weighted is more reasonable.
