The String Cell Battery solution is based on a distributed and modular design that consists of automatically self-organizing cells, which are called String Cells. It is a modular and independent unit inside the string battery. A single String Cell consists of plastic enclosure, an electromechanical cell, a number of contacts, and internal processing capabilities. Through the conductive material on the surface of the enclosure, String Cells form contacts with one another. The terminals of the internal electrochemical cell can be connected to any of the contacts, controlled by the internal processing unit.
A String Cell Battery is a type of rechargeable battery that consists of many individual electrochemical cells placed inside a battery enclosure in random order. The individual cells and the enclosure form a dense, random electrical connection network that can be reduced to create an optimal cell connection circuit which typically consists of many series connected cell strings.
Cell Stations perform cell swapping and charge the string cells. A Cell Station moves string cells from a string battery inside an EV to a storage container and back. It has containers in which the storing and charging of the String Cells takes place. The String Cells in the Cell Station can be charged when the energy price is the lowest. The peak energy consumption of a Cell Station is typically drastically lower than a traditional high-speed charging station. The Cell Stations can be used by the owner as a battery energy storage (BESS), if needed.
