Introducing high-capacity energy storage from Potis Edge

PotisEdge was founded in 2015. The company develops integrated BESS using iCCS (intelligent cell contact system), BMS ( battery management system ) and EMS (energy management system) and offers superior intelligent energy management and storage solutions.

PotisEdge's vision is to create a comprehensive smart energy storage solution. Their independent research and development team is focused on the evolution of our proprietary software, algorithms, system architecture and hardware that form the company's solid foundation.

PotisEdge applies the highest possible standards of quality and security. They have been awarded, among others, the IATF 16949 and ISO 26262 ASIL D certifications , which represent the highest functional quality and safety in the automotive industry.

High-capacity energy storage
Grid-level battery storage, often referred to as grid-level energy storage or large-scale battery storage, is a system primarily designed to store excess electricity from large power plants for later use and to ensure grid stability.

These systems play a key role in balancing electricity supply and demand, which is particularly needed when integrating renewable energy sources such as solar or wind power.

These energy sources are not as predictable as traditional coal, gas or nuclear power plants and cause huge imbalances in the electricity grid unless they are coupled with energy storage systems.

In order to connect a number of solar or wind power plants, the public grid must be supplied with energy storage systems to provide grid services such as frequency regulation, capacity reserves and power curve optimisation.

By storing excess electricity when generation exceeds consumption and releasing it when there is high instantaneous demand, battery storage systems support the reliability and resilience of the energy infrastructure.

How a large-scale energy storage system works
The principles of grid-scale battery storage systems are similar to residential and commercial energy storage systems.

Typically, a large-scale battery energy storage system operates at the MWh level, which distinguishes it from the previously mentioned systems that are much smaller in comparison.

The battery stores excess energy from various energy sources, most commonly solar or wind, during periods of low demand and releases it when demand increases. The energy is stored as direct current (DC) in battery systems, which at the grid level are most often assembled in large shipping containers for easy handling and transport.

Grid-level battery storage systems always work with transformers and power conversion systems (PCS) to provide the transformation between AC/DC and DC/AC.

An integral element of any installation is the energy management system (EMS), which controls the charging and discharging operations of the battery system by monitoring grid parameters and interfacing with grid operators.
