Definition
The string energy storage realizes one-cluster-one-management. Each battery cluster independently controls charging and discharging to avoid the influence of circulating current and realizes fault isolation.The system supports the mixed use of new and old batteries. Long-life battery cells are adopted, and the system life is increased by 30%. The BMS (Battery Management System) adopts an active equalization scheme and is equippedwith PACK-level fire protection. The noise of the whole cabin during operation is less than 70 dB(A)
