The 48V 24Ah lithium battery can travel about 80-90 kilometers.
The different configurations of 48V electric vehicles are generally equipped as standard with a 350W or 400W motor, and on the battery side, there are generally 48V12Ah, 48V20Ah, 48V24Ah, 48V32Ah and other models. . In addition, we can know that since most 48V electric vehicles are national standard vehicles, their speed is around 25 km/h.
Through calculation, we can know that the average current at constant speed is 7.3 A. The current calculation formula is as follows (current = motor power / voltage = 350 W/48 V) and the theoretical driving time. is 3.3h. The driving time calculation formula is as follows (driving time = battery capacity / average current = 24 Ah / 7.3 A). Theoretical mileage is usually around 82.5 kilometers. The formula for calculating driving mileage is as follows, driving mileage = average speed * driving time = 25 km/h * 3.3 h).
When authorities test the cruising range of electric vehicles, there will be specific requirements regarding the weight and size of the tester, and it must also drive at a constant speed. There will also be corresponding requirements. specific requirements regarding driving speed, and even testing requirements, will also be defined. There are also specific requirements regarding ambient temperature and wind speed. However, in the actual use of electric vehicles. , we cannot reach the official test environment, so there is a gap between the officially promoted cruising range and the actual cruising range.
The 48v24ah lithium battery can travel about 65 kilometers.
There are 48 V 24 Ah electric vehicles on the marketequipped with motors of 350 to 600 W. Suppose the motor power is 400 W and the average speed is 25 km/h. mileage, the average mileage of this electric vehicle. The current is motor power/voltage = 400 W/48 V = 8.3 A. The theoretical driving time of the electric vehicle is then battery capacity/average current=24ah/8.3a=2.89h.
In this way we can conclude that the real range of the electric vehicle is the average speed * theoretical driving time = 25 km/h * 2.89 h = 72.25 km. But this is only a theoretical autonomy. Actual range depends on road conditions, driving habits, lift, etc. There are some differences between the actual autonomy and the theoretical autonomy of the different models. Then the 48v24ah electric vehicle can actually travel about 65 kilometers (the data is for reference only).
Note:
VehiclesElectrics generally do not use all the energy before recharging, but charge when there is not much energy left, so a single charge is enough. not enough. It consumes less than 1.2096 kilowatt hours of electricity. It is recommended to charge when there is more than 20% of the remaining power. Do not allow the electric vehicle to be charged multiple times while losing power.
Don't brake too often when driving on the road, otherwise it will also consume electricity. In addition, when charging, you must first plug in the electric vehicle or one end of the battery, and then connect the power.
