Battery & Charger

Battery Capacity (kWh)

Charger Type

Charger Power (kW)

Vehicle Max Rate (kW, optional)

Presets only pre-fill a typical value — charger power stays editable. Effective rate = the lower of charger output and vehicle max rate.

State of Charge

Start (%)

Target (%)

Cost (optional)

Electricity Price (per kWh) DC fast charging often costs more per kWh than home charging — use the price that applies to this charger.

Rough estimate: assumes each stop charges from the low to the high SoC below, on the charger set above. Informational only.

Number of Stops

Per-stop Start (%)

Per-stop Target (%)

Charging to 80% per stop is usually the fastest road-trip strategy, since the last 20% is disproportionately slow.

Result

Enter your battery, charger and start/target charge to estimate charging time using a realistic curve that slows past 80%, with the effective rate, energy added and optional cost — or switch to road-trip mode for a multi-stop total

This uses a simplified two-segment charging curve — full effective rate to 80% state of charge, then a reduced rate for 80–100%. Real charging curves are more complex and taper continuously; actual speed also depends on battery temperature, state of health, the charger sharing power between stalls, and the vehicle's own management logic, so treat this as a planning estimate, not a guarantee. AC (Level 1/2) charging is limited by the car's onboard charger, which is often well below a DC charger's rating. The road-trip figure is a rough informational total and ignores driving time and battery pre-conditioning.
