Product Features
High Reliability
Failure of a single battery module does not lead to battery cluster, container shutdown; single component failure does not lead to the shutdown of the entire energy storage system.
Multi-functional
Peak shaving and valley filling, demand-side management, response dispatch; peak regulation and frequency regulation, backup power, black start.
High Efficiency
Zero series capacity loss, zero parallel circulation; comprehensive cycle efficiency reaches 87%~90%.
Low Maintenance
PACK That is Plug That is and ， Play Station No Stop Machine.
High Safety
1. Inherently safe design of electrical topology, PACK level charge and discharge control, avoiding battery operation in overcharge and overdischarge states from the source;
2. Level active fault isolation, preventing faulty or sub-healthy batteries from operating with faults; Level active fault isolation, preventing faulty or sub-healthy batteries from operating with faults;
3. Flexible interconnection within and between battery clusters, full current (≥157A) within and between clusters balancing.
