Gerotor HPS ®

High Power Storage

With market-leading power density and a significant price advantage compared to Li-ion batteries and supercaps, we are breaking completely new ground here. Based on our highly dynamic short-term storage system, we have developed the Gerotor HPS (High Power Storage) system. With a power density 20 times higher than Li-ion batteries and a significant price advantage over supercaps, we are breaking completely new ground here. If we cannot replace batteries, fuel cells or supercaps, then we supplement these systems and make them better and many times more durable because we take over the dynamic peak loads and protect the existing storage system.

With their highly innovative and active energy management, Gerotor systems are tapping into 3 core markets.

Up to 60% less energy consumption, usually halving the connected load! Elimination of voltage problems, asymmetry and harmonics, “ready for” DC factory networks

High-performance charging everywhere, even where there is a lack of connected load, ultra-fast charging, for example for local transportation.

Any scalability enables applications in the megawatt range. Micro grids can be dimensioned smaller, as the peak load is taken over by the HPS system.

HPS System

The HPS stores energy in the form of a rotating mass and converts this energy into electrical energy. It is designed for highly dynamic processes with permanent charging and discharging and to ensure an uninterrupted power supply.

Power (kW): 30-125
Energy (kJ): 100-2,000′
Response time (ms):< 20ms

SiC inverter

The high-performance frequency inverter uses state-of-the-art silicon carbide (SiC) modules, which ensure exceptionally low rotor losses. It impresses with maximum performance, low space requirements, reduced system costs and high efficiency.

Power (kW): 30-125
Energy (A): 120-150 Frequency (kHz): 60-100
DC Voltage (V): 6560 – 850

STEFF Control

The data-driven control software enables the use of our industrial energy storage systems for all applications and machines. It predicts the necessary target variables of current, voltage and power.

Input signal: V, P
Data processing: Predictive AI
Provision: Cloud service

Energy market “drivers

Reason Effect Result
(Short-term) grid outages Overload and volatility of supply

(> Renewables)

 (Even short) outages lead to hours of production downtime Rising production costs
Supply quality declines Increase in renewable energy sources dto. Rising production costs
Sharp rise in energy costs International conflicts, infrastructure developing too slowly,
rising demand		 Location costs are too high, location is becoming less attractive Disinvestment
Grid infrastructure cannot cope with the growing demand for energy Structural change in the energy supply
(centralized to decentralized)		 Overload and volatility of supply Lack of supply
Maximizing the share of renewable energy Overload and volatility of supply Lack of supply
Power quality due to unstable supply Volatility due to new energy mix Voltage problems, asymmetry, harmonics,
micro-blackouts etc.		 Risk of damage, outages, rising costs
