As an energy storage power station that cooperates with photovoltaic power generation integration, achieves peak shaving and valley filling, load compensation, and improves power quality applications, energy storage batteries are a very important component. When selecting energy storage batteries, the following requirements must be met:
1. Easy to implement multiple combinations to meet higher operating voltages and larger operating currents;
2. The detectability and diagnosability of battery capacity and performance enable the control system to achieve scheduling and control of power plant loads while predicting battery capacity and performance;
3. High safety and reliability: Under normal use, the normal service life of the battery is not less than 15 years;
4. In extreme cases, even if a fault occurs, it should still be within a controllable range, and there should be no accidents that endanger the safe operation of the power station, such as explosions or combustion;
5. Has good fast response and high rate charging and discharging capabilities, generally requiring 5-10 times the charging and discharging capacity; High charge discharge conversion efficiency;
6. Easy to install and maintain;
7. Has good environmental adaptability and a wide working temperature range;
8. Comply with environmental protection requirements, and do not cause environmental damage or pollution during battery production, use, and recycling processes.
