Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the flywheel. Whi. Main componentsA typical system consists of a flywheel supported by connected to a . The flywheel and sometimes motor–generator may be enclosed in a to reduce fricti. .
Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles. .
In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have.

How does a Bess system work?
Most of the BESS systems are composed of securely sealed battery packs, which are electronically monitored and replaced once their performance falls below a given threshold. Batteries suffer from cycle ageing, or deterioration caused by charge–discharge cycles.
How much power does a Bess have?
The system is built of two main blocks. The PCS building block, responsible for the main control of the mobile BESS. The nominal power rating of the PCS block is 225 kVA, with a maximum peak power in the peak shaving mode of 275 kW . The second block is the modular battery pack.
Can a Bess system be scaled?
These all-in-one BESS systems can be scaled from utility scale to industrial and commercial applications. The environmental control system (ECS) within the container combines the fire and HVAC systems to maintain a stable environment.
Do mobile Bess applications have communication interfaces?
This thesis project, carried out at Northvolt Systems, aims to analyze the existing and readily used communication interfaces for a specific set of mobile BESS applications. The analysis is performed by a literature review of typical mobile BESS applications with the identified corresponding communication interfaces.
