The difference in battery range between 60V and 72V electric vehicles is around 25km, while the difference in speed is around 5km/h.
The speed of a 60V electric vehicle, taking the most common 800W motor as an example, its average speed can generally reach 40km/h, while the speed maximum speed of the vehicle is 45 km/h. . Similarly, if a 72V electric vehicle is equipped with an 800W motor, its average speed can generally reach 45km/h, while the maximum speed of the vehicle is 50km/h. By comparison, we can see that the speed difference between 60V and 72V electric vehicles is 5 km/h.
Selection of lithium batteries for electric vehicles
First, determine the specifications of the lithium batteries for electric vehicles we need. Two-wheeled electric vehicles generally operate on 48 V, andthree- and four-wheel vehicles at 60V or 72V.
Second, determine the battery capacity based on the cruising range and motor size. It can be approximately calculated according to this formula: lithium battery voltage * lithium battery capacity / engine power * average speed of the electric vehicle. = cruising autonomy.
Third, the size of the battery is also very important. We need to consider where the battery is placed in the electric vehicle and whether there is enough space.
Fourth, we must choose to purchase regular and quality-guaranteed lithium battery manufacturers.
