RHINO EREV – Range Extender (Cycling + Fuel)
Average-demand drive-cycle estimate + extender cycling time (ON at lower SoC → OFF at upper SoC) and fuel impact (fuel per cycle + km/L equivalent).
Inputs
This is steady-average physics (two-speed mix + optional grade). Great for sizing and investor logic checks.
Battery pack
Extender SoC control band
Extender turns ON at this SoC.
Extender turns OFF at this SoC.
Powertrain & generator
Losses between generator output and energy actually stored in the battery.
Fuel model
Enter measured/estimated liters per hour at your chosen generator output.
Lower is better. This is a modeling input.
Typical gasoline ~0.74 kg/L; diesel ~0.84 kg/L.
Vehicle & environment
Drive cycle
Grade is applied to a portion of the low-speed segment only (simplified).
Cycling assumes average demand remains similar while extender is ON and OFF. Real controllers may cap charge rate or change strategy.
Results
Average demand from drive mix, extender cycling feasibility, and fuel impact.

Fuel metrics assume the extender’s fuel burn rate stays constant while ON. If net charge ≤ 0, cycling and fuel-per-cycle are not achievable under this average demand.
