Calculated according to the most mileage: Battery capacity = 48*15=720WH=0.72KWH. The average power consumption of EV is 12KWH per 100km = 0.12KWH/KM, then the battery should be able to run up to 0.72/0.12=6km.
48V15AH, 350W motor, plus digital odometer, flat road with people test 48 kilometers barely to 50 kilometers
1, there is a relationship with the road conditions, if you go basically uphill, then certainly not up to so many kilometers;
2, with the car's load is also related to the car, if a 180 pounds of man with a 70 pounds of a small girl with the same car the same number of kilometers. If a 180-pound man and a 70-pound girl use the same car with the same capacity of the battery, the number of kilometers run is not the same.
Expanded InformationBecause the battery uses a lead-calcium alloy for the grid, the amount of water decomposition produced during charging is low, and the amount of water evaporation is also low.
Together with the shell using a sealed structure, the release of sulfuric acid gas is also very little, so it has no need to add any liquid compared with the traditional storage battery, docking stakes, power storage time is long and other advantages. The automotive starter battery industry is highly marketized and very competitive. Nearly 2,000 manufacturers of automotive starter batteries in the country (China Electrical Appliance Industry Association lead-acid battery branch statistics).
The distribution of more concentrated areas are Zhejiang Changxing, Hebei Baoding, Guangdong Pearl River Delta, Quanzhou, Fujian, Henan Jiyuan, Jiangsu Su Bei, Shandong Jiaodong Peninsula and so on. With the further increase in the degree of openness of the national market, many foreign-funded battery manufacturers, such as Taiwan Unity, Japan Yuasa and Panasonic (Matzushita), the U.S. Johnson (Johson) and Delphi (Delco) have also entered the Chinese market, and gradually accelerate the process of localization.
