This project aims to develop cloud-native energy management systems for monitoring, controlling, and optimizing medium-scale energy storage systems. The on-site hardware will cooperate with cloud-native energy management software to ensure system functionality, stability, and safety. The cloud-native time-series database and cross-platform monitoring interface can provide high-speed data input/output for statistic analysis, e.g., trend analysis, energy consumption tracking, cost-saving opportunity identification, as well as energy cost and consumption reductions. Moreover, the project can promote the development of the domestic energy storage industry.
