Understanding Battery Energy Storage Systems
14 листопада 2022
What is a battery energy storage system?
Battery energy storage systems convey a simpler way to capture and store energy to use later. They are not typically used to replace grid power completely. Instead, they often offer short-term solutions in applications where there is no access to grid power. Energy storage systems can also replace generators when they are unsuitable due to noise or pollution concerns. They also work with renewable sources of energy, such as solar panels.
Which types of energy storage are there?
There is a broad range of batteries available for use in energy storage systems. However, in recent years, solutions using lithium-ion batteries have grown popular. This technology presents many operational advantages: long working life, light structure, high efficiency and wide operational strange.
How do energy storage systems work?
In a Li-ion battery, the electrolytes carry positively charged lithium ions between the anodes and the cathodes though the separator. When the battery is powering a device, the anode releases lithium ions to the cathode, creating a flow of electrons. In rechargeable batteries, this flow reverses when the battery charges. Then, the lithium ions are released by the cathode and received by the anode.
What are the benefits of energy storage systems?
Lithium-ion batteries enable a new level of sustainability, flexibility and usability, without compromising in power. They are an ideal solution for small businesses with a need for smart power management and for large applications with multiple units. In both cases, they increase the efficiency and often reduce emissions.
Battery energy storage systems can serve as the primary source of power in island mode. And they can also combine with a generator in hybrid mode, enabling smart load management. This versatility allows to effectively address any peaks in power demand.
What are the applications of energy storage systems?
Energy storage systems are very effective in metropolitan construction, telecom applications and events, and working with renewable sources of energy.
In a busy construction site, where peaks in demand usually occur during daytime, energy storage systems complement the power supplied by generators. They can also tandem with a generator to service telecom antennas more efficiently. Also, working in island mode, energy storage systems operate where generator noise is unsuitable, for example at events. And, when combined with a renewable energy source, such as solar panels, energy storage systems can become 100 percent sustainable.
