1. A handling machine comprising:
a variable speed drive control system configured to control at least one variable speed drive, the at least one variable speed drive being associated with one or more of a hydraulic pump electric motor and an electric motor for moving the handling machine with respect to the ground;
a battery configured to power the variable speed drive control system;
a processing unit configured to control the variable speed drive control system;
a voltage converter configured to convert a voltage of the battery, the processing unit being connected to the voltage converter;
a battery cut-off device connected to the battery, the variable speed drive control system, and the voltage converter, the battery cut-off device being configured to close and open a first battery power supply line of the variable speed drive control system and a second battery power supply line of the voltage converter;
a start-up device connected to one or more of the voltage converter and the battery cut-off device;
a charger configured to connect to an electrical power supply network to charge the battery; and
an opening and closing device controllable by the processing unit, the opening and closing device being connected to the battery and to the voltage converter, wherein, when the opening and closing device is in a closed state and one or more of the start-up device and the battery cut-off device are in an open state, the processing unit is powered via the voltage converter.
