4.3.4 Battery
4.3.4.1 Battery Guess
Parameter Possible Values Default Rev HHP Lite Std Adv
Battery Guess Maximum 24.2 – 28.8 V 25 V -,A -
Battery Guess Minimum 22.3 – 26.2 V 22.7 V -,A -
Battery Guess Recover 0 – 30 decimal 15 dec -,A -
These battery parameters can optimise the accuracy of the Battery Gauge.
Battery Guess Maximum is the voltage at which the DX System thinks that the battery
is completely full. The Battery Gauge will show 100% battery capacity at this voltage.
Battery Guess Minimum is the voltage at which the DX System thinks that the battery is
completely empty. The Battery Gauge will show 0% battery capacity at this voltage.
Battery Guess Recover is the maximum voltage drop of the battery during driving. If
the powerchair stops driving, the battery voltage will again increase to its original
level. This increase in voltage does not mean the battery has been charged, just that
the powerchair has stopped driving. Battery Guess Recover is the maximum voltage
increase expected of the battery after driving when no charging has occurred. If the
battery voltage rises by more than this value while the DX System is off, the Battery
Gauge will be updated.
Normally these parameters should be left at the factory pre-set values.
4.3.4.2 Voltmeter Battery Gauge
Parameter Possible Values Default Rev HHP Lite Std Adv
Voltmeter Battery Gauge No / Yes No A -
No – The Battery Gauge shows an estimate of the remaining battery capacity.
Yes – The Battery Gauge shows the battery voltage as an indication of the battery
capacity. This means that the shown value can decrease momentarily during
high load situations (for example: when driving up a slope).
4.3.4.3 Slow Batt Time Scale Driving
Parameter Possible Values Default Rev HHP Lite Std Adv
Slow Batt Time Scale Driving No / Yes No A -
If
Voltmeter Battery Gauge (4.3.4.2) has the value 'Yes', Slow Batt Time Scale Driving
determines the responsiveness of the voltmeter battery gauge.
No – The Battery Gauge has a fast response. This can result in a nervous display
when the powerchair drives over different loads.
Yes – The Battery Gauge has a slow and stable response.
If Voltmeter Battery Gauge has the value 'No', the value of Slow Batt Time Scale Driving
is ignored.
