Electric motorcycle battery
The range of electric cars has always been a concern, because with the development of electric cars, the capacity of electric car batteries is getting bigger and bigger, there are motors that are more and more powerful, and some people need to run long distances using electric cars.
When you buy an electric car, the business will often say that the electric car can run 100 kilometers, but in the actual process of riding, found that the range of the electric car is discounted, some even less than 50 kilometers, in fact, this has a lot to do with the capacity of the electric car battery.
So 48-volt, 60-volt, 72-volt electric car, in the end, how much capacity of the battery can run 100 kilometers? Here for everyone quarantine to say clearly.
The formula for calculating the range of electric vehicles
The range of an electric car is affected by many factors, such as road conditions, temperature, weather, wind, load weight and so on, each parameter will affect the range of the electric car, so even if you use the same electric car, the results of each test may be different.
However, we can also be scientifically calculated to obtain the range of electric vehicles, which is the electric vehicle range formula, through which the model can obtain the theoretical range of electric vehicles.
Range formula: voltage × capacity × speed ÷ motor power = range
The result calculated by the formula is the theoretical range of the electric car, but due to the influence of many factors, the actual range of the electric car is less than the theoretical range, so in order to run 100 kilometers, the electric car should not be less than the calculated profit range at least.
48-volt electric car, how much capacity battery needs to be installed
The 48-volt electric car, generally the new national standard electric car, its motor power is 400w, the battery voltage is 48 volts, the driving speed is 25km/h, if you want to run 100km, you need to configure at least 38Ah capacity.
Voltage × capacity × speed ÷ motor power: 48 × 38 × 25 ÷ 400 = 114 kilometers;
If you configure a smaller battery capacity, such as 32Ah, by calculation, only 96 kilometers of range.
However, owners also need to pay attention to another problem, that is, the new national standard electric car has a weight limit, 38Ah battery, a single weight reached about 9.5 kg, 4, then can reach about 38 kg, while the new national standard electric car is only 55 kg, the new national standard electric car can not be installed such a high-capacity lead-acid batteries, if you must configure a high-capacity battery, it can only choose lithium-ion batteries, but the price may be higher. But the price may be higher.
60-volt electric car, need to install how large-capacity batteries
60-volt electric car generally refers to electric mopeds, generally can be configured with 500-800w motor, we use the most commonly used 600w motor for calculation, the driving speed can be up to about 45km / h, if you want to run 100km, you need to configure at least 24Ah capacity.
Voltage × capacity × speed ÷ motor power: 60 × 24 × 45 ÷ 600 = 108 kilometers;
If you configure a smaller battery capacity, such as 20Ah, by calculation, only 90 kilometers of range.
72-volt electric car, how much capacity battery needs to be installed
72-volt electric car is generally an electric motorcycle, this kind of electric car motor power is more powerful, power performance is stronger, but the driving speed will also be faster, here we follow the most commonly used 1000w motor for calculation, the driving speed can be up to 55km/h, if you want to run 100km, you need to configure at least 32Ah capacity.
Voltage × capacity × speed ÷ motor power: 72 × 32 × 55 ÷ 1000 = 126 kilometers;
If you configure a smaller battery capacity, such as 24Ah, by calculation, only 95 kilometers of range.
