How EV Range Calculator works
The EV Range Calculator uses these inputs: Available energy (kWh), Consumption (kWh/100km). Its primary output is Estimated range. EV calculations connect battery energy, consumption, charging power, losses, and range.
The engine implements R = Bᵤ ÷ E × 100. Validation runs first to reject zero divisors and non-finite values.
Numeric example using the starting values: EV Range Calculator: Available energy (kWh): 55 · Consumption (kWh/100km): 18. The resulting output is Estimated range: 305.56 km.
EV Range Calculator: Limitation for Estimated range: the estimate covers only the displayed fields and does not model unentered road, wear, fitment, legal, or tariff conditions. Charging curves, temperature, battery condition, speed, and road conditions change real results.
💡 Useful Tips
Do not mix units between Available energy (kWh) and Consumption (kWh/100km); make sure both describe the same scenario. Keep a margin for range and charging time, especially with DC charging.
Do not treat EV Range Calculator — Estimated range as mechanical, safety, legal, or financial approval.
Frequently Asked Questions
What does Estimated range mean?
It is the direct output of the formula and entered values, and applies only to the defined scenario.
Which inputs change the result?
The active inputs are Available energy (kWh), Consumption (kWh/100km). Changing any one runs the same formula again. A charger’s rated power is not necessarily delivered to the vehicle throughout the session.
