: 12-volt charging device
1 Four 12-volt batteries ➔ Engine voltage 48 volts
2 One 12-volt battery ➔ Control voltage 12 volts
3 One 12-volt charging device
4 Four charging devices, each with 12 volts
Four 12-volt (4) charging devices must be connected to the battery terminals of the
48-volt engine voltage (1) as in the figure above.
Alternatively, the network with 48-volt engine voltage (1) can be charged in four
steps with a 12-volt charging device (3).
The 12-volt charging device (3) can also be used to charge the control voltage!
