The containerized energy storage system consists of battery clusters, bidirectional power conversion system (PCS), battery management system (BMS), energy management system (EMS), fire protection system, lighting system, dynamic loop control system, access control system, isolation transformer (optional) and so on.Multiple monitoring of system status and hierarchical linkage constitute a comprehensive protection system integrating electrical safety and functional safety. Container system, standardized and pre-fabricated design, reduce customization time and construction costs, and reduce safety hazards caused by local installation differences and management risks. It meets the application requirements of regional power grid in peak regulation, frequency regulation, voltage regulation, emergency response, new energy consumption, etc., and ensures the normal operation or stationary electrical energy of the power system.
The main components of containerized energy storage system consist of a battery module formed by safe, high-efficiency, long-life lithium iron phosphate cells connected in series, and a battery cluster formed by multiple modules connected in series.
The core component of the svstem effectivelv protects the battery from over-charging, over-discharging, over-current, etc., and at the same time manages the equalization of the battery cells to guarantee the safe, reliable and efficient operation of the whole system.
System operation data monitoring, operation strategy management, historical data logging, system status logging, etc.
Bidirectional AC/DC converter can realize the bidirectional conversion of DC to AC and AC to DC, which can either convert AC to DC for charging the battery, or convert DC to AC to supply power to the load or feed back to the grid.
The battery compartment integrates 1200W industrial air conditioner to meet the smooth operation of the svstem in different environments and prolong the service life of the system.
