What are the functions of power storage batteries

What is a battery energy storage system?

A battery energy storage system (BESS) saves energy in rechargeable batteries for later use. It helps manage energy better and more reliably. These systems are important for today’s energy needs. They make it easier to use renewable energy and keep the power grid steady. For example: In 2022, over USD 20 billion was spent on battery storage.

Why is battery energy storage important?

Here are some of the more prominent reasons that make battery energy storage critically important: As mentioned, renewable energy sources such as wind and solar are intermittent, producing energy only when the wind blows, or the sun shines. The periods when these sources generate energy do not always align with when energy demand is highest.

How does battery storage affect energy management?

During periods of high renewable energy generation, such as sunny afternoons, batteries can absorb excess energy. Conversely, during low-generation periods, they can release stored energy to stabilize the grid, demonstrating how battery storage plays a crucial role in modern energy management.

What are the components of a battery energy storage system?

The components of a battery energy storage system generally include a battery system, power conversion system or inverter, battery management system, environmental controls, a controller and safety equipment such as fire suppression, sensors and alarms. For several reasons, battery storage is vital in the energy mix.
