An ESS (Energy Storage System) battery primarily relies on battery modules (such as lithium-ion batteries, sodium-sulfur batteries, etc.) to store electrical energy, with the charging and discharging process monitored by a Battery Management System (BMS). When there is excess power supply, the system stores the energy in the battery. During peak demand or when there is insufficient power supply, the stored energy is released to ensure the stability of the power supply.
ESS battery can release stored energy during peak demand periods and store excess energy during off-peak times. This "peak shaving and valley filling" approach effectively balances grid load, reduces dependence on traditional peak power generation, and enhances the stability and reliability of the power grid.
Renewable energy sources like solar and wind power are intermittent. ESS battery can store energy generated by these sources, providing a stable power supply even during periods without wind or sunlight. This significantly increases the utilization of renewable energy, promoting the adoption of clean energy.
In the event of a grid outage or emergency situation, ESS battery can provide reliable backup power to ensure the continuous operation of critical facilities such as data centers and hospitals, enhancing the reliability and resilience of energy usage.
When selecting an ESS battery, the following factors should be considered:
Capacity and Power Requirements: Choose an appropriate energy storage capacity and power based on actual electricity consumption needs.
Safety: Ensure the battery system has safety features such as overcharge, over-discharge, overcurrent, and temperature protection.
Compatibility: Ensure the ESS battery is compatible with the existing energy system (e.g., solar power systems).
