Method for magnifying efficiency of redox flow battery stack of redox flow battery, involves adjusting manipulated variable by battery management system based on current value such that efficiency of stack is maximized

摘要

The method involves detecting operation voltage at two individual cells (Z1-Zk) of a redox flow battery stack (1) of a redox flow battery using a battery management system. An amount of an appropriate potential gradient is calculated using difference of the operation voltages, and a manipulated variable of the battery is calculated using the gradient based on the dependence of the current value. The management system adjusts the manipulated variable based on the current value such that efficiency of the stack is maximized. An independent claim is also included for a device for magnifying efficiency of a redox flow battery stack of a redox flow battery comprising a battery management system.
