5MWH Energy Storage Battery Container

1. 5MWh High-Density Battery Storage

Capacity & Chemistry: 5MWh total energy (4MWh usable at 80% DoD) via industrial-grade LiFePO4 batteries, powered by 280Ah large-format cells. These cells minimize internal resistance by 35% vs. smaller alternatives, enabling 1C continuous discharge (5MWh in 1 hour) and 2C surge capacity (10MWh for 30 minutes) to handle grid fluctuations or industrial load spikes.

Longevity: 6,000+ cycles (15+ year lifespan) with 80% capacity retention after 10 years, ensuring durable performance for utility-scale deployments or industrial facilities with long operational horizons.

Modular Configuration: Split across 5–6 x 40ft high-cube containers (≈1MWh per container) with parallel/series connectivity, allowing flexible installation and easy scaling to 10MWh+ if needed.

2. High-Voltage PCS for Efficient Conversion

Power Conversion System (PCS): 1MW bi-directional PCS per container (5 units total) with 98.5% efficiency, supporting 800V–1000V DC and 480V–1000V AC 3-phase grids.

Grid & Renewable Integration: Seamlessly connects to utility grids, solar farms, and wind turbines, enabling "peak shaving" (reducing grid reliance during high-tariff hours) and storing excess renewable energy for use after sunset.

Extreme Environment Performance: Liquid-cooled PCS operates in -40°F to 158°F (-40°C to 70°C) with redundant cooling loops, ensuring stable performance in desert heat, coastal humidity, or arctic cold.

3. Advanced Safety & BMS

Battery Management System (BMS): Industrial-grade BMS with real-time monitoring of cell voltage (±2mV balancing), temperature, and current across all 280Ah cells. Features adaptive charging algorithms to prevent overstress and thermal runaway, with automatic isolation of faulty modules to protect the entire system.

Safety Systems: Each container includes FM-200 fire suppression, smoke detectors, and arc flash protection (NFPA 70E compliant). IP66-rated enclosures resist dust, water, and corrosion (salt mist certified per IEC 61701), ideal for coastal or chemical industrial sites.

FAQ 

Q: How does the energy storage container communicate with other energy management systems?
A: The energy storage container communicates with other energy management systems through standard communication protocols such as Modbus, CAN bus, or Ethernet. These protocols enable seamless data exchange, allowing the energy storage container to receive commands and send status information to the central energy management system. This integration helps in optimizing the overall energy operation.

Q: Can the energy storage container be used for electric vehicle charging?
A: Yes, the energy storage container can be used for electric vehicle charging. It can store energy during off peak hours when electricity is cheaper and then supply power for EV charging during peak demand. This not only reduces the strain on the grid during peak charging times but also provides a more cost effective way to charge electric vehicles.

Q: What happens if there is a power failure during the charging process of the energy storage container?
A: In case of a power failure during the charging process, the energy storage container is designed to automatically stop charging and enter a safe standby state. Once the power is restored, it can resume charging according to the pre set charging parameters. The built in safety mechanisms ensure that the batteries and the entire system are not damaged during such power disruptions.
