Can a 48V12Ah (48V 12Ah) electric vehicle battery run far?
To calculate the mileage of a 48V12Ah (48V 12Ah) electric vehicle battery, you need to know the rated power of the electric vehicle motor. The following calculation is based on a 300W power motor:
Example: Electric vehicle battery 48V 12Ah (48V12Ah), with 300W motor, electric vehicle speed is 25km/h (electric vehicle new national standard requires driving speed ≦ 25km/h);
Through calculation: current size = motor power / voltage size = 300W / 48V = 6.25A, that is, the average working current of electric vehicles is about 6.25A;
Driving time = battery capacity / average current = 12Ah / 6.25A ≈ 2.0h, that is, the theoretical driving time of an electric vehicle is about 2 hours;
Driving mileage = driving speed * driving time = 25km/h * 2h ≈ 50km, that is, the theoretical driving mileage of electric vehicles is about 50 kilometers;
That is: an electric vehicle with a 48V12Ah electric vehicle battery and a 300W motor has a theoretical driving range of about 50 kilometers.
Of course, there are 400W, 500W, 600W motor powers for electric vehicles, which can be calculated based on the actual motor power and then combined with the above calculation method to get the theoretical mileage;
In addition, the above is calculated based on theoretical data under ideal conditions. The actual driving process is difficult to be consistent. After all, each rider has different weights, different riding habits, different roads, and different places of climate and environment. Therefore, the above The theoretical mileage can only be used as reference data.
The above is organized by Shenzhen BENWEI lithium battery, please refer to it.
