How far can a 72V 20Ah electric vehicle travel?

72V 20Ah electric vehicles can typically travel about 50 kilometers. The battery specification 72V 20Ah indicates that the electric vehicle is equipped with four 20Ah batteries, where 72V is the rated voltage of the battery and 20Ah is the rated capacity. The rated voltage of the battery determines the optimal operating voltage for the connected electrical appliances, and the rated voltage of the battery provides a reference value for the output voltage of the charger, which should be greater than 72V. An electric vehicle, also known as an electric drive vehicle, is powered by electricity and is divided into AC electric vehicles and DC electric vehicles. It uses batteries as the energy source, converting electrical energy into mechanical motion through components such as controllers and motors, and controls the speed by adjusting the current. The battery in an electric vehicle is the power source, typically a lead-acid battery that can be recharged and reused.
As a regular e-bike commuter, my 72V 20Ah battery-powered vehicle can typically cover about 80 to 100 kilometers on a full charge, depending on riding habits and conditions. With a battery capacity of 1440 watt-hours and an energy consumption of approximately 15 to 20 watt-hours per kilometer, the calculated range is 72 to 96 kilometers. However, in practice, I've noticed that uphill climbs or windy days can reduce the range to around 70 kilometers, while downhill routes or maintaining a steady 25 km/h speed can extend it beyond 90 kilometers. Weight plays a significant role too: carrying a passenger or luggage immediately decreases the range by about 10%. In cold weather, battery efficiency drops, potentially limiting the range to just 75 kilometers. I recommend new owners use an app to track several trips and record real-world data for more accurate commute planning. Always charge more before long trips—don't rely on theoretical maximums.
After using an electric scooter with similar specifications for two years, I've concluded that its range is quite suitable for daily commuting. A full charge of the 72V 20Ah battery easily supports my round-trip commute for three days, covering a total distance of about 85 kilometers. For example, the one-way distance from home to the office is 10 kilometers, making a round trip of 20 kilometers. Over five days, that would total 100 kilometers, but considering traffic lights and frequent stops, I need to recharge after three full days. On weekend outings, I tested the range: it easily covered 80 kilometers on flat roads, but only managed 70 kilometers on hilly terrain. After one year, the battery capacity degraded by about 5%, so while the new battery could cover 90 kilometers, it now only reaches around 85 kilometers. Developing a habit of timely charging and avoiding complete discharge helps maintain the range within a stable range.
