ev constant power charging time calculator online

Use ev constant power charging time estimate online for battery kWh, initial pct, target pct, charger kW, efficiency pct. Idealized vehicle-system arithmetic using supplied measurements. This does not establish component suitability, safe modifications or actual performance.

How to use it

Enter battery kWh. Set initial pct, target pct, charger kW, efficiency pct. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
battery kWhMain input. Positive values. 60
initial pctOption. Zero or positive values. Maximum 100.20
target pctOption. Zero or positive values. Maximum 100.80
charger kWOption. Positive values. 11
efficiency pctOption. Zero or positive values. Maximum 100.90

Calculation method

hours = battery_kWh*positive(target_pct-initial_pct)/100/charger_kW/positive(efficiency_pct/100) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply ev constant power charging time estimate to the case below, keeping the displayed units and assumptions. Idealized vehicle-system arithmetic using supplied measurements. This does not establish component suitability, safe modifications or actual performance.

Choose the right tool

Distinguish geometric estimates from measured vehicle performance. Tire rolling behavior, engine losses, charging curves and braking systems depend on actual conditions. Calculations do not establish fitment, roadworthiness or safe modifications.

Limitations and common mistakes

  • Idealized vehicle-system arithmetic using supplied measurements. This does not establish component suitability, safe modifications or actual performance.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
