1. The power supply capacity of the 48V20AH battery is: 48V×20AH=960WH (watt hour)

2. The “life time” of a 450W motor is: 960WH÷450W=2.13 hours.

3. There are many factors that affect the speed of electric vehicles, so they are all based on the “endurance time”: under rated load, they can drive continuously for 2.13 hours.

Two people, 150KG load, 48V20AH battery can run 40 kilometers, if one person rides alone, 70 kilometers with a small throttle. The size of the throttle greatly affects the mileage.

The 48V12A battery can theoretically run 40-50 kilometers with a load of 300 kg. If you often pull goods, consider downloading the heavy king. The 60V20A or 72V20A is definitely better than the 48V single design car.

The question of how far a 48V electric car can run is mainly attributed to the problem of the battery capacity of the electric car, and of course there are many other objective factors. Electric vehicles rely on electric vehicle batteries (commonly used: lead-acid batteries) to provide power. The weight, speed, service life, mileage, starting performance, etc. of the vehicle are closely related to the electric vehicle battery

Electric vehicle battery specifications are based on voltage (V) and capacity (AH). Consumers can look at the parameters of electric vehicles when they choose to buy electric vehicles. The specifications of electric vehicle batteries will be mentioned above. How far a 48V electric vehicle can run is also a major demand issue when choosing a car and battery capacity. Generally, this refers to the round-trip journey in one day. Battery power and motor power determine the size of the mileage. The motor size of current electric vehicles is basically fixed, so the distance traveled can basically be estimated.

The simple electric bicycle is longer and uses a 48V12AH battery 48V12AH electric bicycle can run about 35 kilometers. Luxury electric vehicles use 48V20AH batteries for longer periods, and 48V20AH electric vehicles can run about 70 kilometers. High-power electric vehicles and electric motorcycles use 64V20AH batteries for longer periods, and 64V20AH electric vehicles can run about 90 kilometers.

Then why do some friends’ electric car batteries not go far? Mentioned here specifically refers to lead-acid batteries. 　

The main reasons that affect the battery of electric vehicles are not far away: Environment temperature: 1. When the ambient temperature drops, the battery usage time will be shortened accordingly. According to empirical calculations, the battery capacity will drop by nearly 1% for every 1°C drop in room temperature, so the battery life of electric vehicles is short in winter. 2. Depth of discharge: Depth of discharge is often said to be the degree of battery usage in electric bicycle riding. The deeper the depth of each discharge, the shorter the battery life. Simply put, after the battery is charged once, the longer the electric vehicle is used, the greater the depth of battery discharge. 3. Road traffic problems: For the above data, it is basically on a flat road. If the slope is larger and more, the distance run will be reduced. 4. Actual conditions such as load capacity and frequency of starting brakes. 5. Electric vehicle battery charging time: The charging method of electric vehicle battery is very important. Improper operation will damage the battery
