Product Features
High Safety
► Independently controls the charge and discharge status of each battery module (approximately 20 cells in series), preventing battery overcharge or over-discharge abuse from the source.
► Timely online isolation of sub-healthy battery modules.
► Topology-level intrinsic safety design, intrinsic shutdown of the PACK-level circuit in the non-operating state, three-level control system architecture, complete protection for voltage, temperature, current, and insulation;
► 100μs battery overcurrent protection lock, removal of battery modules with safety hazards or entire cluster lock, multi-level fuse configuration, protection against serious faults;
► Perfluorohexanone fire suppression, three-level early warning and fire suppression design.
High Reliability
► Failure of any single battery module does not cause the battery cluster to shut down.
► Failure of any single battery module does not cause the battery stack to shut down.
► Failure of any single component does not cause the entire energy storage system to shut down.
Multi-functional
► Peak shaving and valley filling, demand management, response scheduling, peak regulation and frequency regulation, backup power, black start
High Efficiency
► No parallel circulating current
► Low cable usage
► AC-side efficiency ≥88% (including auxiliary losses)
► Liquid cooling
Low Attenuation
► No series capacity loss
► No battery cluster parallel circulating current
Convenient Delivery
► Battery stack, full current control system, fire suppression, and air conditioning are all integrated within a single container.
► Integrated delivery, only DC bus interface and communication interface to the outside.
Convenient Maintenance
► Routine inspection once every 12 months.
► Replacement of faulty battery modules and power conversion units is plug-and-play.
