A proven principle reimagined:
what do we, pottery and NASA have in common?
The flywheel is the oldest known method for storing energy: In fact, even the potter’s wheel uses the principle of storing rotational energy, as did the spinning top. With AMPERAGE, the modern 4th generation high-performance flywheel energy storage, this principle is raised to a new level.
Made of carbon fiber, with integrated magnetic bearings and operating in a high vacuum, AMPERAGE convinces with its high efficiency and almost unlimited number of charging cycles. And it is even based on a principle that NASA has already worked on.
Charge Cycles
How the technology works
An electric motor accelerates the flywheel to charge up the high-performance energy storage system. In generator mode, the motor decelerates the flywheel again and the energy stored during rotation is converted back into electricity.
Carbon-fiber flywheel
Novel integrated hollow cylinder design – the flywheel rotates around the stator. The design affords the highest capacity and is cost-effective to manufacture. The modular store rotates at up to 16,000 rpm and can be charged as often as required.
Motor / Generator
The external rotor synchronous machine accelerates the flywheel mass when charging and decelerates it again as a generator when discharging. The machine demonstrates high power density and great efficiency and dynamics. Even at full load, the power is reversed in a highly dynamic manner within less than 30 milliseconds.
Magnetic Storage
The high speeds and high energy density are only made possible thanks to the contact-free magnetic bearing. The industrially proven storage system is efficient and wear-free. The storage system has a maintenance interval of two years.
Vacuum Housing
Operation of the flywheel mass in a high vacuum at up to 1 x 10-5mbar minimizes air friction and contributes to the high efficiency of the storage system. The vacuum housing also safeguards the system’s safety, even at 1.2 x overspeed.
Sustainable increase in performance
Designed for maximum performance
As an highly powerful system, AMPERAGE is designed to store energy with maximum efficiency in the smallest installation space and release it again with maximum output. Designed as an external rotor based on a rotating hollow cylinder made of high-strength material, the storage system is extremely robust.
Sustainable, versatile, smart
As a mechatronic energy storage, AMPERAGE is subject to hardly any aging – it can be charged and discharged as often as you like during its 25-year lifespan. Its unique modular design allows it to be customized to a variety of different application-specific requirements.
Modular and scalable
The modular design accommodates needs-based systems, ranging from individual systems to larger clusters consisting of several energy storage systems. This means that the features of the systems can be conveniently adapted and new applications made accessible.
AMPERAGE is made from the highest quality components from European and German mechanical engineering sources. We combine quality and sustainability right from the outset.
Standalone housing for outdoor installation
The energy storage systems are delivered in a specially manufactured housing designed for outdoor installation. It is designed to protect against vandalism and water splashes and reduces to a minimum the transport outlay and local space required thanks to its compact design.
Packaging customized to the application
On request, the series product can also be equipped with appropriate power electronics and peripherals for specific applications. Making it ready for every application.
Compact and safe for every application
Cloud visualization and data analysis
AMPERAGE performance data can be accessed securely and in real time over a cloud-based data dashboard. Sophisticated tools deliver customer-specific insights into system dynamics, efficiency and economy.
Application-specific digital twins – i.e. system-parallel online simulations – provide information for optimizing the mode of operation.
Energy Management
If necessary, AMPERAGE can act autonomously by monitoring grid conditions such as voltage or frequency or by reacting to control commands from the customer’s inhouse energy management system. Minimum response times of less than 30 milliseconds can be achieved in this way, even with full power reversal.
Human-machine interface for easy access
The energy storage system offers a human-machine interface for interacting with AMPERAGE and the energy management system. Personalized user profiles allow different users to be set up – from read-only to full access to all parameters for commissioning the system. Remote access can also be implemented if desired.
Remote access for full transparency.
Installation and commissioning
AMPERAGE is always installed and commissioned by the specialists from Adaptive Balancing Power.
About the procedure itself: approval for delivery is only granted once the factory acceptance test (FAT) has taken place. Once commissioning at the customer’s site has occurred, final acceptance takes place.
Service and maintenance plans
Adaptive Balancing Power supports each project with service and maintenance plans. If the customer wishes, annual maintenance can be carried out by the customer’s own trained staff, but the detailed system inspection every two years should be carried out by the specialists from Adaptive Balancing Power. Continuous, real-time system diagnostics take place over the Adaptive Cloud.
