A battery energy storage system is a sub-set of energy storage systems, using an electro-chemical solution. In other words, a battery energy storage system is an easy way to capture energy and store it for use later, for instance, to supply power to an off-grid application, or to complement a peak in demand. They are usually not used to replace grid power completely but instead used to offer short-term solutions in applications where access to grid power is intermittent or the use of a generator is unsuitable due to noise or pollution concerns. Energy storage systems are also often used to manage energy generated from intermittent sources, such as solar panels.
A variety of different battery technologies is available for use in battery energy storage systems. However, in recent years solutions using Lithium-Ion batteries have grown in popularity, driven by their long working life, wide operational strange, lightweight structure, high energy-efficiency, and, crucially, the falling cost of the technology . These, combined with the low total cost of ownership and sustainability, make them attractive for several applications.
A Li-ion battery comprises:
Atlas Copco’s ZenergiZe range is a good example of how the high-density li-ion batteries can be leveraged to enable a new level of sustainability, flexibility, and usability, without compromising on power.
