The invention relates to a transportation means, a device and a method for determining a voltage of a cell (1b) of a string (I) of multiple cells (1a, 1b, 1c, 1d, 1e, 1f) connected in series of an electro-chemical energy storage means. The method comprises the following steps: supplying, in a duty cycle, an input of a low-pass filter (11) with an input voltage, the cell (1b) being at least involved in the production of said voltage; adjusting the duty cycle in such a way that the output voltage reaches a predefined value across an output of the low-pass filter (11); and determining the voltage of the cell (1b) from the adjusted duty cycle.
