About the EV Charging Engine
This calculator determines the exact cost to refill your EV’s battery. Charging is never 100% efficient; electrical resistance generates heat. This engine assumes a standard 10% charging loss, meaning it takes ~1.11 kWh of grid power to put 1.0 kWh into your battery.
Pricing Rule: Public DC Fast Chargers (like Tesla Superchargers or Electrify America) are significantly more expensive than residential electricity due to peak demand charges and infrastructure costs. Maximizing home charging is the key to unlocking the true financial benefits of EV ownership.
