At present, the market is divided into different models. The mainstream lead-acid battery models are 36V12Ah, 48V 12A, 48V20Ah, 60V 20Ah, 72V20Ah. Someone asked, why are batteries of the same model or capacity used in different models, but there is a significant difference in mileage?

In fact, it is very wrong to judge the endurance of electric vehicles based on only one type of battery. There are many factors that affect the endurance of electric vehicles, such as motor power, controller power, tires, vehicle weight, road conditions, and riding habits. Influential, even the same car has different battery life under different riding conditions. In this case, we can only approximate a comprehensive estimate.

Ideally, it is equipped with a set of 48V20Ah lithium batteries and a new national standard electric bicycle with a power of 350W motor. The maximum current of the electric bicycle is I=P/U, 350W/48V=7.3A, and the maximum discharge time of the 48V20Ah battery is 2.7 Hour, then at the maximum speed of 25km/h, 48V20AH battery can run 68.5 kilometers, this is the case of only considering the motor, then the weight, controller, lights and other power consumption are only 70- 80% of the electricity is used for vehicle driving, and the full speed is 25km/h, so the actual maximum endurance comprehensive estimate is about 50-55 kilometers.

Assuming a 600W portable electric scooter, the maximum speed can run 40km/h, the same group of 48V20Ah batteries, the maximum working current is 12.5Ah, the maximum discharge time is 1.6 hours, ideally, a 600W motor portable electric scooter The maximum endurance can reach about 64 kilometers, including power consumption, and the actual maximum endurance comprehensive estimate is about 50 kilometers.

Therefore, when you buy a car, the battery life of an electric car cannot be judged by the battery capacity alone. Even the same battery, different models, and different operating conditions will have different range. Everyone is buying a car. At the time, the mileage given to you by the merchant is only a reference value. In actual circumstances, it is difficult to reach this standard. In addition, as time goes by, the battery will also experience a decline in aging capacity. In addition, the parts of the electric vehicle begin to age, and the battery power consumption increases. This is why many people feel that the battery life of their car is getting shorter and shorter.

If you want to increase the cruising range, it is recommended to remove some unnecessary functional configurations, especially the lamps and audio equipment that consume a lot of power. When riding, do not keep high-power discharge, adjust the driving speed appropriately, and maintain your battery.
