How far can a 72V battery travel?

[DeNathan]

A 72V20Ah electric vehicle typically can travel approximately 60-70km when fully charged. Generally, a 72V20Ah electric vehicle is equipped with a motor of around 1000W, resulting in an average constant current of 13.9A, which theoretically translates to a driving time of 1.4 hours. Assuming an average speed of 50km/h, it can be concluded that a 72V20Ah electric vehicle can travel 70km. The formula for calculating the average current is: Average constant current = Motor power / Voltage = 1000W / 72V. Precautions for charging electric vehicles: The battery should be charged promptly after use and should not be left unused for extended periods, as this can lead to sulfation of the battery plates. When the charging indicator light turns green, it indicates that the battery is ready for use or is mostly fully charged, but there is still a slight gap from 100%. It is recommended to perform a prolonged charge weekly or biweekly, meaning continuing to charge after the green light turns on. After timely charging, the battery begins the sulfation process once discharged, with noticeable sulfation occurring within 12 hours. Prompt charging can mitigate less severe sulfation, helping to maintain the battery in as good a condition as possible.
