11 Battery Gauge
Refer to Chapter 1 sections 8 and 10 for how to read the battery gauge.
The battery gauge typically starts to flash slowly when the battery voltage falls below
23.3V whilst the scooter is driving on a level surface. The controller can be programmed
to inhibit the low battery flash, please refer to SP1 Programming and Diagnostic
Technical Manual.
For optimum accuracy of the battery gauge and low battery indicator, the controller
should be programmed with the approximate nominal capacity of the scooter battery.
However, accuracy is not greatly affected if the programmed type and capacity do
not closely match the battery.
The most important factor affecting the accuracy of the battery gauge is the resistance
of the cable and connections between the battery and the controller. The controller
must be matched approximately to the cable resistance of your scooter to make the
battery gauge accurate, (see Programming and Diagnostic Technical Manual).
As a guide, 2.5 mm
2
cable has a resistance of about 8 m Ω per meter; 4 mm
2
cable
has about 5 m Ω per meter and 6 mm
2
has about 3.3 m Ω per meter. Circuit breakers
and connectors usually account for about 15 m Ω .
These values will be chosen at the time the controller is being specified by the scooter
manufacturer. Like the preset acceleration rates, once the values for the battery are
decided, they are programmed into controllers during manufacture and should never
need changing.
