Abstract

The invention discloses a method, a system and a storage medium for solid-phase concentration correction of a lithium battery. The method includes establishing an electrochemical model of the lithium battery; initializing a solid phase concentration in the electrochemical model to be a first solid phase concentration; simulating the simulated output voltage of the lithium battery in a preset period according to the electrochemical model, the preset current and the first solid-phase concentration; acquiring the actual output voltage of the lithium battery in the preset period; calculating an error coefficient between the simulation output voltage and the actual output voltage, and presetting an error threshold corresponding to the error coefficient; and when the error coefficient is greater than the error threshold, performing iterative correction on the first solid phase concentration until the error coefficient is not greater than the error threshold, and outputting the corrected second solid phase concentration.
