An energy storage battery system is a battery component used to store electrical energy, and it mainly consists of the following parts:
Battery packs consist of multiple individual battery cells that can store and release electrical energy. Types of batteries include lead-acid batteries, nickel-metal hydride batteries, and lithium-ion batteries.
Control system: Used to control the charging and discharging process of the battery pack, including charge/discharge controller, data acquisition module and communication module, etc.
Temperature control system: Used to control the temperature of the battery pack to prevent overheating or overcooling from damaging the battery pack, including temperature sensors, cooling system, etc.
Protection devices: Protective measures used to control abnormal conditions such as overvoltage, undervoltage, overcurrent, and short circuit of the battery pack, including fuses, protective relays, etc.
Monitoring system: Used to monitor the status and performance of the battery pack in real time, including indicators such as power, voltage, and temperature, and can perform fault diagnosis and alarm handling for the battery pack.
The main functions of energy storage battery systems include the following aspects:
Storing electrical energy: storing electrical energy supplied by the power grid or other power sources so that it can be released when needed, thereby improving energy utilization efficiency.
Load balancing: To cope with peak loads on the power grid, making the grid operation more stable and safe.
Peak shaving: By releasing electrical energy during peak load periods, the demand for electricity is reduced, thereby alleviating the power burden and maintaining power balance.
Emergency backup: In the event of a power grid outage or other emergency, the energy storage battery system can provide backup power to maintain the normal operation of part of the load.
Increase the output power of photovoltaic power plants: By applying energy storage battery systems in photovoltaic power plants, the output power of photovoltaic power plants can be increased by storing solar energy during the day in the batteries and releasing it at night or during cloudy or foggy weather.
In conclusion, energy storage battery systems play an important role in achieving energy transition and improving energy efficiency.
