E-Bike Charging Time Calculator

Calculate the charging duration for a battery of an e-bike. The battery size in watt-hours (Wh), the charging current in ampere (A) and the charging voltage in Volts (V) should be indicated at the recharger or in its manual. The charging of the battery is somewhat constant up to a charge level of 80%. After that, the charging will become considerably slower. So if you enter a target above 80%, the calculated time will be too short.
Please enter the first three values and change level of charge and charge target to fit your needs. The charging time in hours and minutes will be calculated. The calculated value is a theoretical minimal value, practically it will take a bit longer.

Battery energy:
Charging current: A
Charging voltage: V
Level of charge: %
Charge target: %

Charging time: h min

Example: a battery with 350 Wh should be loaded from 10 to 80 percent. The recharger charges with 2 amperes and 36 volts. So the charging time will be almost 3 1/2 hours.
