Abstract

The invention discloses a cell detection method, electronic equipment and a computer readable storage medium. A cell comprises N cell electrical cores, and the N is an integer not smaller than 1. The method comprises steps that for each electrical core, in M charging / discharging cycle periods, a first parameter of each charging / discharging cycle period is determined; the first parameter represents a discharging window; the M is an integer not smaller than 2; the M first parameters are utilized to adjust a first coefficient of a first linear function to make a curve corresponding to the first linear function satisfy point distribution of a first point set, and a second parameter is determined; the first point set comprises M points formed by the first parameters and the corresponding cycle periods; the second parameter represents a fitting degree; the first coefficient and the second parameter are utilized, in combination with detection strategies, whether the electrical cores are in cycle risks is determined.
