Estimate how long an electric bicycle takes to charge between two state-of-charge levels. Adjust usable capacity, charger output, charging efficiency, and taper allowance to model the actual battery and charging setup.
State of charge percentages are converted to decimals; power is in kW and energy in kWh.
The main result estimates elapsed plug-in time under steady available power. The secondary values separate energy stored from energy purchased.
The vehicle’s onboard charger, battery temperature, balancing, and charger sharing can make real sessions longer.
With the defaults, the battery gains 0.36 kWh. After charging losses and taper allowance, the displayed time follows from dividing outlet energy by 0.12 kW.
The formula section identifies each driver. Change one input at a time to see its effect while holding the others constant.
Yes, but rated values may reflect controlled test conditions. Measured capacity, consumption, session, or charging data usually gives a more representative planning result.
Use measured outlet and battery energy when available. Otherwise, treat the loss or efficiency field as an explicit scenario assumption rather than a universal value.
Temperature, battery controls, equipment limits, riding conditions, maintenance, and measurement timing can all change the outcome.
No. It is a planning estimate based on the values entered and does not replace vehicle, battery, charger, or warranty documentation.
| Input | Role |
|---|---|
| Usable capacity | Energy available within the battery operating window |
| Efficiency | Share of outlet energy stored in the battery |
| Taper | Extra time for reduced charging power |
