Understanding and Mitigating Inter-Cluster Circulation in Battery

Inter-cluster circulation is a critical issue in Battery Energy Storage Systems (BESS) that can significantly impact the lifespan and efficiency of batteries. It refers to the flow of current between battery clusters, which can cause imbalance and degradation over time. Understanding the causes and implementing preventive measures is crucial to maintaining the

Circulation system

Of course, there are still tap losses and heat storage losses even after the circulation system is switched off. In the present case, the losses are lower solely because the water temperatures are nearer 40 °C rather than 60 °C. The hot water systems commonly used today "work" predominantly for compensating the heat losses of the systems.
