Chapter 4: Programming the Rhino2
4.4.7.4 Battery Gauge Warning
Battery Gauge High Warning
Battery Gauge Low Warning
Battery Gauge High Warning sets the voltage at which a high-voltage condition is indicated.
Battery Gauge Low Warning sets the voltage at which a low-voltage condition is indicated.
4.4.7.5 Battery Cut-Off Voltage
This parameter is only used when Deep Discharge Beeper (4.4.1.10) has the value 'Yes'.
The Battery Cut-Off Voltage specifies the voltage at which the battery is empty and battery
damage will occur if the battery is discharged any further. If the battery voltage falls below
90% of this value, the RHINO2 gives the user an audible warning.
The cut-off level for lead-acid batteries is 21V.
Note:
An audible deep discharge warning is required to comply with ISO7176-14.
4.4.7.6 Battery Gauge Dead-band
Prevents the battery gauge from increasing when the battery voltage recovers after driving.
If the scooter is driving, the battery voltage will be lower than when the scooter stands still.
However, the actual charge of the battery does not increase during standstill, even though
the voltage has increased. This can cause the battery gauge to increase as well, showing a
charge that is too high during standstill.
Battery Gauge Dead-band makes sure that the battery gauge only shows a higher charge
when the battery is actually being charged. Any increase in battery voltage that is lower
than the value of Battery Gauge Dead-band is ignored.
