ABSTRACT:
The method modifies the coupling of the elements of electrochemical generator by commutating means enabling, according to the conditions of operation, the coupling of at least two groups, for example identical, of said elements either in parallel, or in series. The commutating means are actuated, as a function of at least one of the parameters of the power demanded at the motor, in such a way that whatever the rotary speed of the motor, parallel coupling is effected in all cases where the power demanded can be supplied by this coupling. A signal of the power demanded is established as a function of at least one parameter of the power actually delivered, and of at least one threshold signal corresponding to the maximum value which the abovesaid parameter can take, all things being otherwise equal, in parallel coupling. The signal of the power demanded and the threshold signal are compared and the passage from series coupling to parallel coupling is actuated when the signal of the power demanded is less than the threshold signal. The parameter selected may be the average voltage (U.sub.M) of the induced coil of the motor or an image of this voltage.
