Nowadays, many electric bicycles cannot drive fast, but their range is much higher than that of electric motorcycle or moped. Many people don't understand this. It is clear that electric bicycles are small in size. How can they run so far? Today, let's take a look at the maximum range of 48 volt electric bicycles?
With the continuous improvement of battery technology, the increase of battery capacity and the development of lithium battery technology, the range of electric vehicles has also been greatly improved. Now many manufacturers claim that their electric bicycles are able to run 100 kilometers, and some even say that the maximum range is 200 kilometers. Is that true?
The theoretical range value is different from the actual riding
When an electric bicycle is riding with light load, for example, a girl weighing 40 kg keeps driving at a speed of 20 km/h in summer, the road condition is always flat, and the battery is new, so the range can be calculated as 100 km.
However, if a 90 kg man takes a 40 kg child to ride together in winter, speed remains 23-25 km/h, and always rides up the slope, even if it is also a new battery, the range might be only 50 to 60 km.
Therefore, the calculation of the real range should consider the speed, load, temperature and road conditions, which cannot be generalized.
What is the value of increasing range
So, is it necessary to develop lithium batteries with larger capacity to increase the range? In fact, it is unnecessary. For example, if we make the capacity of the lithium battery to 48 volts, 32A or more, even reach 48 volts 50A, can the range reach 200 kilometers?
Through the test of a 48V26Ahlithium battery, the range is indeed further. If a 48V50Ah lithium battery is installed according to this theoretical value, the theoretical value can last for 200km at a time.
Practical is better for actual riding
However, the theory is only theory. For electric bicycles, it is appropriate to maintain a range of 30-50km. If the range is too long, first, the cost will increase, and the price of an electric bicycle with lithium batteries may be higher than that of an electric motorcycle with 60V batteries; Second, the riding experience will be bad if it’s a too-long-time riding. For example, people would feel tired if the mileage exceeds 30 kilometers.
