1000 kwh Batteries Commercial Use
1 MWh battery energy storage system is an integrated energy storage device designed. The equipment features energy-saving, small footprint, high energy density, and strong environmental adaptability.
1 MWh Battery vs 1000 KWh Battery
We all know that M is abbreviation for million and K is abbreviation for thousand. So, 1 MWh is equal to 1000 KWh. they are both units of electricity. They are often used in large electrical installations or in large energy storage systems.
What is included in a 1 MWh battery storage system?
The energy storage system consists of cabinets, liquid cooling units, PCS inverters, EMS energy management systems, BMS battery management systems, lithium battery clusters, energy storage high-voltage boxes, fire protection systems, electrical systems, and safety auxiliary systems.
Battery pack:
The 1 MWh battery pack consists of 75 pcs 51.2V 280Ah lithium battery modules. The modular combination is more flexible and allows you to adjust the number of battery modules according to your actual power needs.
PCS Inverter
The primary function of a PCS inverter is to facilitate the conversion of electrical energy between the grid and the battery. The PCS inverter supports both grid-connected and off-grid operation modes.
Grid-tied operation: On the AC side, the outdoor cabinet is connected to the grid, while the DC side is internally connected to the lithium battery. This setup can be applied in scenarios such as power capacity expansion, solar energy storage, peak shaving, and valley filling.
Off-grid operation: On the DC side, the outdoor cabinet is connected to the lithium battery. The system operates to output three-phase AC voltage with fixed frequency and effective value, ensuring continuous power supply to AC-side loads.
Battery Management System (BMS)
The BMS is suitable for managing energy storage batteries, performing numerical calculations, performance analysis, alarm handling, and data storage based on real-time battery data. Additionally, it can be integrated with the PCS inverter host, EMS energy management system, etc., to ensure stable operation of all battery systems by implementing coordinated control. This involves optimizing load control strategies based on output power requirements and SOC (State of Charge) of each battery group.
Temperature control system
The temperature control system of the 1000 KWh battery system can keep the temperature inside the battery cabinet within the range of 10℃~30℃. This way the battery can always be kept within the optimal working temperature range. Keeping the working efficiency of the battery always in the maximum state.
20GP Container
The design of the integrated energy storage high voltage box can isolate the battery from the external environment to avoid the battery receiving damage. It also integrates the various electrical components of each energy storage system for easy coordination and monitoring and management.
Electrical cable system
This includes the connection cables between the batteries, circuit breakers, protection switches, communication cables, etc.
Energy Management System
This actively balances the batteries and ensures that the charge, voltage and charge/discharge currents of each battery module are consistent. This extends the service life of the batteries and reduces the negative impacts of the short-plate effect of the barrel.
Fire Fighting System
The storage containers are equipped with a fire extinguishing system and a salt spray alarm device. If a dangerous situation occurs, they can make a warning in the fastest time, so that the fire extinguishers can quickly eliminate the fire.
