- the battery switch device 2 has been brought into the closed position (ON position).
- the closing of the switch system 21 of the battery switch device 2 enables the drive control system 7 to be energized by the battery 1 (at the level of the supply terminal 71 of the drive control system 7).
- processing unit 5 is not yet powered, and the drive control system 7, controlled by the processing unit 5, cannot operate, since the start-up device 3 is still in the open state.
- each of the switch systems 31, 32 goes into the closed position, so that the power line L23 connected to terminal 311 can now supply line L34 which extends from terminal 312 of device 3 for switching on.
- converter 4 which allows converter 4 to provide a suitable supply voltage to processing unit 5 which, as shown in Figure 6, has a supply input terminal 54 connected to converter 4.
- the screen 9 also has a supply terminal 94 connected to the output of the converter 4, which allows the supply of the screen 9.

- the processing unit 5 activates the controllable opening and closing device 6 which switches to the closed position.
- the controllable opening and closing device 6 thus allows the current to pass between the battery 1 and the converter 4, so that the line of power L64 which connects the battery 1, the controllable opening and closing device 6 and the converter 4 is also under voltage.
- This controllable opening and closing device 6 makes it possible to maintain the power supply to the voltage converter 4 and therefore to the components which are powered by the converter 4, such as the processing unit 5, even when the start-up 3 or the battery switch device 2 is open. Indeed, the power line L64 can take over from the power line L34.

- terminal 58 of unit 5 is connected to terminal 821 of controllable opening and closing system 82 of the charger and the other terminal 822 of system 82 opening and controllable closing is connected to the output of the converter 4, so that the closing of the controllable opening and closing system 82 which results from the connection of the charger 8 brings a voltage to the level of the terminal 58 which is detected by the unit 5 treatment.
- Screen 9 displays the progress of the initialization. The power line L27 of the control system 7, and the power line L64 connected to the converter 4 remain de-energized. Charging has not started yet.
- the processing unit 5 controls the closing of the device 6 for opening and closing controllable as illustrated in FIG. 11 to activate the line of power L64, which makes it possible to maintain the power supply to converter 4 in the event of disconnection of charger 8. Charging of battery 1 can begin.
- the processing unit 5 transmits to the charger via the CAN bus 1598 a signal to the charger 8 to trigger the charging of the battery 1.
- the opening of the controllable opening and closing system 81 which results from the supply stoppage of the charger 8 enables the processing unit of 5 to detect the absence of voltage at the level of the terminal 58 and triggering an extinction preparation operation as detailed below.
- the closed state of the controllable opening and closing device 6 makes it possible to maintain the power supply to the processing unit 5 which can control the display on the screen of information relating to the state use of the machine and in particular on the fact that the charger 8 has been disconnected, for example to warn the user.
- the processing unit 5 performs its preparation operations for switching off (including the saving of data such as the information relating to the disconnection of the charger).
- the unit 5 commands the opening of the device 6 for opening and controllable closing, which allows the electronics of the machine to shut down cleanly and find itself in the configuration of Figure 4.
- the charger 8 is electrically powered via its socket 83 which is connected to the mains.
- the supply of the charger 8 causes the closing of the systems 81, 82 of controllable opening and closing as illustrated by the dotted lines in Figure 12, so that the processing unit 5 detects the connection of the charger 8 by the intermediary of the controllable opening and closing system 82, the closing of which brings the output voltage of the converter 4 to the terminal 58 of the processing unit 5.
- the processing unit 5 also detects that the battery switch device 2 and the start-up device 3 are closed by respectively detecting the output voltage of 4 at terminals 52 and 53 of the processing unit. .
- the processing unit 5 is configured to prohibit the use of the machine as long as the battery switch device 2 and the start-up device 3 remain closed.

- the processing unit 5 can perform data recording operations to anticipate the opening of the battery switch device 2 and of the start-up device 3.
- the processing unit 5 warns the operator, for example by controlling the display of the screen 9 that the conditions for taking charge are not met, because the battery switch device 2 and/or the device 3 switch-on are in the closed position, and can ask the operator to open the devices 2, 3 in order to proceed with the charge.
- controllable opening and closing device 6 remaining closed, the processing unit 5 remains powered during the battery charging process, which allows it to record information and warn the user when needed, for example via the screen.
- the processing unit 5 can record information relating to the charge, in particular to the disconnection, and inform the user of this disconnection .
- the processing unit 5 can prepare to switch off as explained above.
