RamHino Parameters

Lithium System parameters for RamHino Lithium sys-
tem are shown below
RamHino First group:
1. Voltage (V): It is the total level of the cells volt-
age. As the cells are connected in series, this is
the total pack voltage considering the 12, 15, 22,
24 or 26 cells. The minimum voltage for every
cell is 2800 mV, while the maximum voltage is
3-36

3600 mV (average value). Figure 3-6 shows the
range of admissible voltages.
NOTE: When the cells are not under charge or under dis-
charge for some time, they try to reach a nominal
value of approximately 3300 mV irrespective of their
charge status.
The Voltage (V) when checked on a machine that is
not working or that is not under charge is approxi-
mately 39.6V on 38V battery pack (3.3*12), 49.5V on
48V battery pack (3.3 X 15), 72.6V on 72V battery
pack (3.3 X 22), 79.2V on 76V battery pack (3.3*24)
and about 85.8V on 83V battery pack (3.3*26).
To check the minimum real value of voltage, the
battery pack must be under discharge. An arm or
one or more stabilizer can be moved for some time
so that there is a voltage drop and the voltage value
measured is real.
To check the maximum value of voltage, the battery
pack must be under charge. 110-220V power cable
must be connected for at least five minutes to mea-
sure the voltage.
