A commercial energy storage cabinet is a device used to store and manage electrical energy, often used in industrial, commercial and grid applications. A complete commercial energy storage cabinet usually consists of the following key parts:
1.Battery unit: This is the core part of the energy storage cabinet and is used to store electrical energy. Common battery types include lithium-ion batteries, lithium iron phosphate batteries, and lead-acid batteries.
2.Battery Management System (BMS): Responsible for monitoring and managing the status of battery cells, including voltage, temperature, charging status, etc., to ensure the safe and efficient operation of the battery.
3.Inverter: Converts direct current (DC) to alternating current (AC) to power AC equipment or feed back to the grid.
4.Power control system (PCS): includes charger and inverter, used to manage the charging and discharging process of the battery to ensure efficient conversion and transmission of electric energy.
5.Energy management system (EMS): used to optimize and control the operation of the entire energy storage system, manage the flow of power, and ensure the efficiency and reliability of the system.
6.Cooling system: Used to maintain batteries and electronic equipment within a suitable temperature range to prevent overheating.
communication system
7.Safety system: including fire detection and suppression system, overvoltage protection, overcurrent protection, etc., to ensure the safe operation of the system.
8.Cabinet: Provides physical protection and prevents environmental factors such as dust, moisture, and mechanical damage from affecting internal components.
9.Other auxiliary components: such as power distribution units, circuit breakers, terminal blocks, etc., to ensure reasonable distribution of power and safe operation.
These parts work together to achieve the main function of a commercial energy storage cabinet, which is to store electrical energy and provide stable power output when needed. These components may vary depending on the specific application and needs, but the basic structure is roughly the same.
