About this free ev charging time estimate tool
Estimate charging duration from capacity, charge levels and average charging power. Calculators answer a defined arithmetic question using the values you supply. Keep units and currencies consistent, choose the correct starting amount and inspect the assumptions before using a result. Estimates do not replace a lender quotation, an official tax rate, a medical assessment or a jurisdiction-specific deadline rule.
A practical example
A concrete example uses usable battery capacity (kwh): 60; starting charge (%): 20; target charge (%): 80; average effective power (kw): 12. The result is Energy added (kWh): 36 Charging hours: 3.
Before you rely on the result
Use consistent measurements and check packaging or manufacturer guidance. The estimate excludes unusual shapes, installation losses and site-specific requirements unless entered. Use average effective power, not peak charger rating; tapering affects duration.
