Control of an electrochemical device with integrated diagnostics, prognostics and lifetime management

A method for controlling an operation of an electrochemical device comprising at least one internal regulatory system, the method comprising the steps of:

• receiving measurements related to the operation of the electrochemical device, and estimating at least diagnostics data based on said measurements,
• estimating prognostics data based on said estimated diagnostics data and providing operation instructions to control said internal regulatory system of the electrochemical device, said operation instructions being optimized with respect to said estimated diagnostics and said estimated prognostics data,
• wherein a feedback of operation instructions data is provided to estimate said prognostics data, and said prognostics data are estimated further on the basis of said operation instructions,
• and wherein said diagnostics data includes reversible disruption data, and said operating instructions are based at least on said reversible disruption data so as to counteract current reversible disruption, and
• each occurrence of determining said operating instructions on the basis of reversible disruption data being stored in a memory, and said prognostics data being estimated further on the basis of a number of occurrences of counteracted reversible disruptions,
• wherein said diagnostics data includes at least data of a current state of health of the electrochemical device, including an assessment of a possible degradation of the electrochemical device, and the prognostics data include at least an estimation of a remaining useful life time of the electrochemical device, and
• where said reversible disruption data are related to faulty operation of the electrochemical device and are detected by variation of at least externally measured variables including at least a voltage response of the electrochemical device.
