General information
- Short Summary
- A new type of high-voltage macrocell developed by a German university makes it possible to store energy with a total voltage of up to 20,000 volts. For this purpose, individual modular storage modules (“FOXe”) with a voltage of up to 1500 volts are joined together in tube systems to form a high-voltage macrocell. The university offers a license agreement as well as a technological co-operation.

A new type of high-voltage macrocell developed by a German university makes it possible to store energy with a total voltage of up to 20,000 volts. For this purpose, individual modular storage modules (“FOXe”) with a voltage of up to 1500 volts are joined together in tube systems to form a high-voltage macrocell.
As the energy revolution proceeds, battery storage for electrical energy is becoming increasingly important. Current battery stacks top out at 1,500 volts, leading to high material usage and high heat loss at high output. The high-voltage macro cell from a German university is different. Individual FOXe storage modules are assembled in pipe systems to form a macro cell providing up to 1,500 volts. Battery systems consisting of parallel or series macro cells can produce up to 20,000 volts. The advantage is that the modular structure allows scaling to create a large overall storage system with efficient maintenance, operation, and assembly. “Cell balancing”, which extends the service life of individual cells, can also be implemented. The position of stacked individual storage cells can be changed easily within the overall system, contributing to a balanced cell load.
This technology is of particular interest to companies in the energy and electrical engineering sectors as well as in the field of storage and battery technology.
The university offers a license agreement as well as a technological co-operation. - Advantages and Innovations
- The technology’s general advantage is that the high voltages mean much lower currents at the same output level – there is less waste heat, and less material is required for current distribution. The invention allows modular energy storage system structures for up to 20,000 volts. It is suitable for use in cargo vehicles and especially well suited to energy storage at the medium-voltage level.
