RHINO – Multi-Source Charging Calculator
Use this tool to estimate how long it takes to charge the RHINO battery pack from different sources – onboard generator, home / depot AC, and DC fast charging – for a chosen state-of-charge window.
This calculator is aimed at fleets and planners who want to compare real-world turnaround times and plan charging strategies for RHINO operations.
What this calculator helps you answer
- How long it takes to charge the pack from X% to Y% using:
- the onboard generator alone,
- a typical home or depot AC charger,
- and DC fast charging (where available).
- How charging time changes with pack size and SoC window.
- How different power levels (kW) affect turnaround time for fleets.
How to use it
- Enter the RHINO battery pack size in kWh (for example, 48–96 kWh range depending on configuration).
- Set the start and target SoC (for example, 20% → 80%).
- Enter the available power for each source (generator kW, AC kW, DC fast kW).
- Compare the resulting charge times to plan depot, route, or overnight charging strategies.
For simplicity, this model assumes constant charging power – real vehicles may taper at high SoC or limit generator output under certain conditions.
Multi-Source Charging Time Calculator
Compare charge time from generator and different charger types for the same battery pack and SoC window. Includes pack C-rate limit.
Inputs
Set the battery size, SoC window, efficiency and max C-rate, then enter power for each source.
