How far can a 72 volt, 20 amp lithium battery for an electric vehicle run? How many kilometers can he travel?
The following uses data to give you a detailed answer...
To calculate the cruising range of the 72V20Ah electric vehicle lithium battery, you need to know the nominal power of the electric. vehicle engine. The following uses a motor power of 800W. Here is an example calculation for everyone:
Example: An electric vehicle lithium battery is 72V20Ah, equipped with a motor of 800W, and the speed of the electric vehicle is calculated. like 35 kilometers per hour;
By calculation:
Current size = motor power/rated voltage = 800W/72V≈11.1A, it's that is to say, the average operating current of electric vehicles is about 11.1 A;
Driving time = Battery capacity/yardaverage ant = 20 Ah/11.1 A≈1.8 h, i.e. the theoretical driving time of an electric vehicle is approximately 1.8 hours;
< p>Driving mileage = driving speed * driving time = 35 km/h *1.8 h≈63 km, that is, the theoretical range of an electric vehicle is about 63 kilometersThat is to say: an electric vehicle with a 72 V 20 Ah electric vehicle lithium battery and an 800 W motor has a range theoretically about 63 kilometers.
Of course, the motor power of electric vehicles also includes 500W, 600W, 1000W... You can calculate the theoretical mileage according to the actual motor power and the method of calculation above

In addition, the above is calculated based on theoretical data under ideal conditions. After all, every cyclist has different weight, different riding habits, different roadsdifferent and different roads. local climatic environments, so the above theoretical mileage can only be used as reference data.
