Provider of real time reconfigurable storage solutions for Grid-connected applications
Today battery storage systems are usually composed of a battery with several serial/parallel fixed interlinked cells.
In such a system the same current goes through all cells. Once the first cell is fully discharged, the operation is stopped.
Thus the system is limited by the least efficient cell.
The least efficient cell is the one that endures the strongest discharges which quickens its ageing compared with the others thus reducing the whole performance even faster.
In order to suppress this limitation SwitchESS implements an active balancing and conversion solution, based on the use of low voltage transistors managing each cell of the pack.
