For a 48V electric car to run 80 kilometers, at least what capacity lithium battery does it need?
If a 48V electric vehicle wants to run 80 kilometers, how much lithium battery is needed for an electric vehicle? You need to know the rated power of the electric vehicle motor. The following calculation is based on a 300W power motor:
Example: The working voltage of an electric vehicle is 48V, with a 300W motor, and the speed of the electric vehicle is calculated at 25 km/h (required by the national standard);
via calculations:
Working current = motor power / nominal voltage = 300W / 48V = 6.25A, that is, the average working current of electric vehicles is about 6.25A;
Driving time = desired mileage / driving speed = 80KM / 25KM/h = 3.2h, that is, the electric vehicle needs to travel more than 3.2 hours to reach 80 kilometers;
Battery capacity = working current * working time = 6.25A * 3.2h = 20Ah, that is, if you want to run 80 kilometers, you need at least 48V20Ah lithium battery for electric vehicles;
That is: a 48V electric vehicle with a power of 300W motor needs at least a 48V20Ah lithium battery for an electric vehicle to run 80 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 calculations are 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 driving conditions, and different local climate environments. Therefore, the above The theoretical mileage can only be used as reference data.
The above is organized by BENWEI battery, please refer to it.
