What is a battery energy storage system?
With the increasing importance of renewable energies, the need for efficient energy storage solutions is also growing. Battery energy storage systems (BESS) play a key role here - they make it possible to store energy and retrieve it when needed, reducing dependence on the power grid.
Whether for private households or large companies: BESS are essential for a reliable and constant power supply. They store renewable energy when it is available and release it when needed. In this way, they contribute to an efficient and sustainable power grid.
How battery energy storage systems work
Battery energy storage technology is based on a simple but effective principle: during charging, electrical energy is converted into chemical energy and stored in batteries for later use. The system works according to a three-stage process:
Charging: During the day, the storage system is charged with clean solar energy
Optimizing: Intelligent battery software and algorithms coordinate solar production, weather forecasts and electricity tariffs to optimize the use of the stored energy
Discharge: The stored energy is released in a targeted manner when consumption is high to avoid expensive electricity costs
Central components of a battery energy storage system
An effective battery energy storage system consists of several coordinated components:
Battery storage: This is where the energy is stored in chemical form. Lithium-ion batteries are particularly popular due to their high energy density and efficiency. New technologies such as flow batteries and solid-state batteries are further expanding the possibilities.
Inverters: This important component converts the stored direct current (DC) into alternating current (AC), which is required by most electrical devices.
Control systems: These monitor and control the charging and discharging processes to ensure optimum performance and longevity.
The interaction of these components enables reliable energy storage for a wide range of applications - from private households to industrial operations. Our energy management system at HIS Energy has been specially developed to ensure a reliable and efficient power supply.
