How it works
Includes a user-supplied charging efficiency, but not real-world power tapering, standing charges or parking fees. The time estimate assumes constant charging power.
Estimate cost, added range and ideal charging time for an electric car.

Energy added = battery capacity × (target% − start%) ÷ (100 × efficiency). Includes a user-supplied charging efficiency, but not real-world power tapering, standing charges or parking fees. The time estimate assumes constant charging power.
With battery capacity (kwh) 60, starting charge (%) 20, target charge (%) 80, charging efficiency (%) 90, electricity price per kwh 0.27, charger power (kw) 7, the estimated charging cost is $10.80. Energy from charger: 40 kWh; Energy added to battery: 36 kWh; Ideal charging time: 5h 42m 51s.
