Truck List
On the left hand side is the truck list. You can have as many trucks as you would like to evaluate.
...
The available curves are Rimpull, Retard, Fuel and , Trolley Assist Rimpull, Battery Usage, Battery Regen, Regen Force.
Turn curves on and off using flags in the Active column.
Curves are digitized out of the manufacturer's handbooks. For better accuracy, calibrate with data from your fleet management system.
Click in the graph area to manually show a point.
Curves can be copied into and pasted from Microsoft Excel using Copy to Clipboard and Paste from Excel buttons.
...
Braking curves are not used to calculate stopping distances. The deceleration properties are set in Setup > Settings > Acceleration.
In the presence of regenerative braking, this remains to be the normal non regenerative brakes.
Fuel Curve (For Fuel Power Trucks)
Fuel curves show the fuel consumption in liters per hour at different engine loads. Haul Infinity uses this to calculate total fuel burned on each haul cycle .
...
if the trucks power source is Fuel (Setup > Trucks > Limits > Power Source)
...
Calibrate this graph with data from the fleet management system.
This is not needed for use with battery powered truck.
Trolley Assist Rimpull
Trolley Assist provides an (optional) secondary rimpull curve, which is used when trucks cross traverse a Trolley Assisted segment.
...
Segments have a trolley property. When toggled on, the truck switches to the trolley rimpull curve while traversing the segment.
Battery Usage (For Battery Power Trucks)
Battery Usage curves show the power consumption in kilowatts, at different ground speeds, while at full throttle. Haul Infinity uses this to calculate total battery energy used on each haul cycle if the trucks power source is Battery (Setup > Trucks > Limits > Power Source > Power Source Type).
...
This is not needed for use with Fuel powered trucks.
Battery Regen (For Battery Power Trucks)
Battery Regen curves show the power restore to the batteries in kilowatts, at different ground speeds, while fully utilizing the regenerative brakes. Haul Infinity uses this to calculate total battery energy restored on each haul cycle if the trucks power source is Battery (Setup > Trucks > Limits > Power Source > Power Source Type).
...
This is not needed for use with Fuel powered trucks.
Regen Force (For Battery Power Trucks)
Regen Force curves show the braking force at the rim is kilograms force, at different ground speeds, while fully utilizing the regenerative brakes.
...
This is not used to calculate max safe down hill speeds like the retard curve, it’s just used to calculate the amount of the current braking that corresponds to regenerative braking and from that how much energy is being restored.
This is not needed for use with Fuel powered trucks
