How many kilometers can a 48V 52Ah battery run?
2 Answers
48V 52Ah battery can run 48-60 kilometers. Motor aspect: From current models, 48V electric vehicles are generally equipped with 350W or 400W motors, which have relatively low power and thus lower speed. Additionally, as most of these vehicles comply with the new national standards, their maximum speed is around 25km/h. Battery factors: 48V electric vehicles usually offer three battery options: 48V12Ah, 48V20Ah, and 48V24Ah. If an electric vehicle is equipped with a 48V24Ah battery and a 350W motor, the average current is about 7.3A (motor power/voltage), with a theoretical runtime of 3.29h (battery capacity/average current), resulting in a theoretical range of about 82 kilometers (theoretical runtime X speed). If the vehicle has a 48V24Ah battery and a 400W motor, the theoretical range is about 72 kilometers. On average, an electric vehicle with a 48V24Ah battery has a theoretical range of around 77 kilometers.
The range of this 48V52Ah battery depends on the specific vehicle it's used in. My old e-bike had a similar specification, and it could actually run anywhere from 50 to 90 kilometers. It mainly depends on the vehicle's weight and speed. My bike is lightweight, and at a steady speed of around 20 km/h, it could last a week of commuting without needing a charge. However, if carrying two people uphill, the battery drains quickly, possibly reducing the range to just over 40 kilometers. Regular maintenance also affects the range—for example, insufficient tire pressure or rusty bearings can increase power consumption. In short, don't rely too much on advertised numbers; it's more reliable to test it yourself a few times.
