How far can a 48V20Ah electric bicycle run?
Since the implementation of the new national standard, all localities have increased the promotion of national standard electric bicycles. Affected by the new national standard, 48V20Ah electric bicycles have become a new choice for many users. In this regard, many users asked me: How far can the 48V20Ah run? Can the endurance exceed 50km? Regarding this issue, let's give you a detailed explanation.
Let's first look at the various parameters of the 48V20Ah electric bicycle. The battery voltage is 48V and the battery capacity is 20Ah. Generally speaking, the motor power of this type of car is about 400W, and the average speed is about 25km/h.
Through the power and voltage of the motor, we can get that the average current of 48V20Ah at a constant speed is 8.3A (motor power/voltage=400W/48V). Then through the battery capacity and average current, we can conclude that the 48V20Ah theoretical driving time is 2.4h (battery capacity/average current=20Ah/8.3A). In addition, through the theoretical driving time and average speed, we can conclude that the theoretical cruising range is 60km (average speed*theoretical driving time=25km/h*2.4h).
From the above data, we can conclude that the theoretical battery life of a 48V20Ah electric bicycle can reach 60km, but considering the difference in motors of different models and other accessories, the actual battery life of different models may still be somewhat different from the theoretical battery life. The difference. But generally speaking, it will only last longer than the theoretical battery life. Why do you say that?
Let's look at the actual battery life of the three representative models. The MQi2 urban version is equipped with a 48V20Ah lithium battery and a 400W motor, with a cruising range of more than 65km; the Xiaodao Xiaoluo 20 version is equipped with a 48V20Ah battery and a 350W motor, with a cruising range of more than 70km; the Luyuan FEA Scarab is equipped with a 48V20Ah lithium battery and The 350W motor has a maximum cruising range of 80km.
From the perspective of comprehensive theoretical battery life and actual vehicle battery life, the 48V20Ah electric bicycle has a range of about 60 to 80km, which can easily exceed 50km. However, it should be noted here that both the theoretical battery life and the actual vehicle battery life are calculated using new cars as an example. If it is a model that has been used for many years, the actual battery life will decrease. So, how far can your 48V20Ah electric bike go?
