What Are the Components of the Lithium Iron Phosphate Battery Pack Energy Storage System?

Lithium iron phosphate batteries have a series of unique advantages such as high working voltage, high energy density, long cycle life, and environmental protection, and support stepless expansion. After forming an energy storage system, large-scale electric energy can be stored. With the rise of the energy storage market, some power battery companies have deployed energy storage business to open up new application markets for lithium iron phosphate batteries in recent years. The following is an introduction to the components contained in the lithium iron phosphate battery pack energy storage system.

1. Lithium iron phosphate battery control system

The lithium iron phosphate battery energy storage system is controlled by a programmable logic controller and a man-machine interface. One of the key functions of the system is to control the charging time and rate of the energy storage system. For example, a PLC can receive real-time data on electricity prices and decide how quickly to recharge a battery system based on the allowable maximum demand, state of charge, and peak/off-peak price comparisons. This decision is dynamic and can be optimized on a case-by-case basis. It integrates with the rest of the system through standardized communication inputs, control signals and power supply. It can be accessed via dial-up or the Internet. It has multiple layers of defense to restrict access to its different functions, and provides customized reporting and alerting capabilities for remote monitoring.

2. Lithium iron phosphate battery power conversion system

The function of the power conversion system is to charge and discharge the battery and provide improved power quality, voltage support and frequency control to the local grid. The energy storage battery has a complex and fast-moving, multi-quadrant, dynamic controller (DSP) with dedicated control algorithms capable of switching output across the full range of the device, i.e. cyclically from full power sink to full power output. It works well for reactive power and any combination of demands for active and reactive power.

3. Lithium iron phosphate battery stack

The stack is composed of several single cells. The lithium iron phosphate battery pack energy storage system can economically store and provide large-scale power according to demand, and the main mode is fixed. It is a long-life, low-maintenance, high-efficiency technology that supports stepless expansion of power and energy storage capacity. Energy storage systems are particularly effective for renewable energy suppliers, grid companies and end users.

The lithium iron phosphate battery energy storage system can be applied to all links of the power supply value chain, and can convert intermittent renewable energy such as wind energy and solar energy into stable power output; the optimal solution for power supply in remote areas. The deferral of grid fixed investment, and the application of peak-shaving and valley-filling. The energy storage battery system can also be used as a backup power supply for substations and communication base stations. The iron-lithium battery energy storage system is environmentally friendly, and has the lowest degree of ecological impact among all energy storage technologies, and does not use elements such as lead or cadmium as the main reactant. In the process of continuous research and development and practice of the energy storage system, in addition to designing corresponding solutions to some practical problems, it has further made practical work on other remote monitoring, cloud management systems, big data collection and analysis, and energy storage battery recycling. development and application. This will continue to be applied and improved in future power station energy storage, household energy storage, communication energy storage and other different energy storage systems.
