Electric vehicles (EVs) draw power from the electrical grid, turning kilowatt‑hours (kWh) into miles. Understanding how much energy a car uses per distance travelled is the first step to estimating its charging cost.
The total energy required each day depends on the driver’s daily distance and the vehicle’s efficiency, usually expressed as kWh per 100 km. Because charging is not 100 % efficient—some energy is lost as heat—the grid must supply a bit more than the theoretical need.
By multiplying the adjusted energy demand by the local electricity price and adding any fixed connection fees, we obtain a realistic daily charging cost. This calculation helps users compare EV operating expenses with conventional fuels and make greener choices.
