For a 48V electric car to run 100 kilometers, at least what capacity lithium battery does it need?


How much lithium battery is needed for a 48V electric car to run 100 kilometers? You need to know the rated power of the electric car motor. The following calculation takes a 300W power motor as an example:


Example: The working voltage of the 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);


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 = desired mileage / driving speed = 100KM / 25KM/h = 4h, that is, electric vehicles need to travel more than 4 hours to reach 100 kilometers;


                 Battery capacity = working current * working time = 6.25A * 4h = 25Ah, that is, to run 100 kilometers, at least 48V 25Ah electric vehicle battery is required;


That is: a 48V electric vehicle with a power of 300W motor needs at least a 48V25Ah electric vehicle battery to run 100 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.
