Abstract
The battery unit includes a storage battery (AC) with an integral charge control circuit (CC). The charge control circuit (CC) includes a switch (S) adapted to prevent or allow charging current (Ic) to flow into the storage battery (AC), said switch (S) being controlled by a measuring system for measuring at least one physical parameter (T1, Tn, Vb) representative of the state of the storage battery (AC) in order to command successive opening and closing of the switch (S) to chop said charging current (Ic) if said measured physical parameter crosses a predetermined threshold The end of charging of the storage battery is then optimized by the battery unit itself, so that a simple constant current generator is sufficient to charge the storage battery satisfactorily.
