Recently, a cargo bike user asked me such a question: is it better to use 48V batteries or 60V batteries for electric cargo bike? My answer to this question is that the battery capacity is the same, and 60V battery is better; If the battery capacity is different, it is better to choose a battery with a large capacity. Why do you say that? The following is a detailed interpretation of the data.
First, let’s take a look at the 48V battery. The main battery models are 48v32ah, 48v45ah and 48v58ah. The motor is generally equipped with 600W power. Generally speaking, the average speed of the cargo bike can reach 25km / h. Taking 48v32ah battery as an example, through calculation, we can get that the average current is about 12.5A (motor power / voltage), the theoretical endurance time is 2.56h (battery capacity / average current), and the theoretical endurance is about 64km (theoretical endurance time * average speed).
Similarly, we can get that the electric tricycle is equipped with 48v45ah battery, and the theoretical range can reach 90km; If the electric tricycle is equipped with 48v58ah battery, the theoretical range can reach 116 kilometers.
Secondly, let’s look at the 60V battery. The main battery models are 60v32ah, 60v45ah and 60v58ah. The motor power is also 600W. Generally speaking, the average speed of the vehicle is 25km / h. Through calculation, we can get that the electric tricycle is equipped with 60v32ah battery, and the theoretical range can reach 80km; If equipped with 60v45ah battery, the theoretical endurance can reach 112 km; If equipped with 60v58ah battery, the theoretical range can reach 145 km.
Through comparison, we can find that if the batteries are of the same capacity and different voltages, the 60V electric tricycle has a longer endurance. Taking 48v32ah and 60v32ah batteries as examples, their theoretical endurance is 64km and 80km respectively. In this case, it is better to choose 60V batteries. However, if it is a battery with different capacity and different voltage, the battery with large capacity generally has a longer endurance. Taking 48v45ah and 60v32ah batteries as examples, the theoretical endurance is 90km and 80km respectively. In this case, it is better to choose 48V batteries; Taking 48v32ah and 60v45ah batteries as examples, the theoretical endurance is 64km and 112km respectively. In this case, 60V batteries are better.
To sum up, when the battery capacity is the same, it is better to choose 60V battery. If the capacity is different, the battery with larger capacity is preferred. Of course, one thing to note is that in addition to battery life, 60V batteries are generally more powerful than 48V batteries. So, how would you choose?
