This is a hybrid device that combines the properties of a battery and a supercapacitor. It has rapid charge/discharge capabilities and long cycle life. It's found in applications requiring frequent charging and discharging, like regenerative braking systems and some power backup solutions.
A Reliable Source of Power in Industries
SAFT batteries provide a reliable source of power when the main source cuts off. They are mainly used in backup power systems in industries and telecommunication systems to prevent system failure when blackout happens, which in turn will cause loss of data or damage important equipment.
Uninterruptible Power Supply (UPS)
Factories use SAFT batteries in their Uninterruptible Power Supplies (UPS) to provide power immediately when cut off, which allows critical operations like computing, communication, and manufacturing to continue smoothly without any interruptions. This battery can stand and provide power until the generator is fully loaded or the main switchboard takes over.
Energy Storage Systems
SAFT batteries are also used in Renewable Energy Systems like wind and solar power systems to store excess energy that can be used later on when the system has not produced energy or at night. As industries heavily rely on renewable energy sources to power their daily activities, these batteries are paramount in stabilizing the energy supply and ensuring smooth operations.
Electric Vehicles
These batteries are also applied in the electric vehicle industry. As electric vehicles provide an ecologically friendly and low-maintenance means of transportation from one place to another, SAFT batteries are responsible for providing the energy needed for their operation.
Grid Frequency Regulation
Large industrial applications with huge loads contribute to the stability of the electrical grid by absorbing excess energy during periods of low consumption and supplying energy back during peak consumption periods. This helps maintain a steady frequency across the grid, enhancing the reliability of the electric supply to all users.
In conclusion, SAFT batteries are directly applied to ensure that there is continuous operation, that safety and reliability are enhanced, that greens are followed up, and that efficiency is increased in industrial applications.
