Recently, an electric bike user asked me such a question, that is, how far can an electric bicycle run with a 10 yuan electricity bill? Can it reach 1000km? For this problem, let's analyze in detail through several common models.
First of all, what we need to know is that the average residential electricity price is 0.5135 yuan/KW·H, which means that 10 yuan of electricity is about 19.5 kilowatt-hours of electricity.
Secondly, let's look at 48V electric bicycles. The mainstream battery models are 48V12Ah and 48V20Ah, and the motor is generally 350W. Through the relevant test data, we can know that the theoretical battery life of 48V12Ah is about 40km, and a charge requires about 0.64 kilowatt-hours of electricity. From this we can know that one kilowatt of electricity can make 48V12Ah run 62.5km, and the electricity fee of 10 yuan can make 48V12Ah run 1218km ( 62.5km*19.5). Similarly, the theoretical battery life of 48V20Ah is about 65km, and a charge of about 1.06 degrees is required. This means that the electricity cost of 10 yuan can make the 48V20Ah run 1190km (65km/1.06*19.5).
Next, let's look at 60V electric bicycles. The mainstream battery models are 60V20Ah and 60V32Ah, and the motor is generally 600W. Through the relevant test data, we can know that the theoretical battery life of 60V20Ah is 70km, and it takes about 1.32 degrees for a charge. From this, we can conclude that the electricity fee of 10 yuan can make 60V20Ah run 1034km. The theoretical battery life of 60V32Ah is 110km, and it takes about 2.12 degrees for a single charge, which means that the electricity cost of 10 yuan can make 60V32Ah run 1012km.
Finally, let's look at 72V electric bicycles. The mainstream battery models are 72V20Ah and 72V32Ah, and the motor is generally 800W. Through the relevant test data, we can know that the theoretical battery life of 72V20Ah is 90km, and its charge capacity is 1.59 degrees. The theoretical battery life of 72V32Ah is 140km, and its charge capacity is 2.54 degrees. From this, we can conclude that the electricity cost of 10 yuan can make 72V32Ah run 1075km.
On the whole, the 10 yuan electricity fee can make the 48V mainstream electric bicycles reach 1190-1218km, and the 60V mainstream electric bicycles can reach 1012-1034km, and the 72V mainstream electric bicycles can also reach 1075-1103km. In other words, 10 yuan electricity bill can make mainstream electric bicycles have a battery life of more than 1000km. Of course, the above data is in the ideal state of the new car, so there may be some differences in actuality.
