The mileage of an electric bicycle is defined as follows: "When the battery is fully charged, the rider's weight is configured to be 75 kg to ride on a flat secondary road (under the condition of no strong wind), and the battery voltage is lower than 10.5V/ knot, so cut off the power supply. The riding mileage obtained under the above conditions is called the driving mileage of electric bicycles. "
Generally, the continuous mileage of brand-name electric bicycles equipped with 36V 12Amp-hour batteries is about 45-60 kilometers, while the nominal mileage of some manufacturers will rise to 70-80 kilometers, which is suspected of false propaganda. Because reaching this nominal value means that the efficiency of its motor is improved by nearly 40% compared with that of famous brand factories.
If the efficiency of the motor produced by a well-known brand factory is 75% under the above working conditions, it is obviously impossible for the motor efficiency of the factory with a nominal 70-80 km to reach more than 100%. This is a special reminder to consumers.
In the actual use process, how many kilometers to drive with sufficient electric energy is related to many factors. The factors related to the manufacturer are mainly the efficiency characteristics of the motor, the capacity and life characteristics of the battery, and the factors related to other objective conditions are: the weight of the rider, the road conditions that he often rides, whether it is necessary to use the brakes frequently, and the riding habits of the rider.
Another problem that consumers need to be reminded is that with the increase of service time, the battery capacity will gradually decrease, and the mileage with sufficient electricity will also decrease. When the maximum driving distance of the old battery can't meet the traffic demand of one day, we can consider sending the battery for maintenance or replacing it with a new battery.
Extended Information Electric vehicles can be divided into: electric bicycles, electric motorcycles, electric unicycles, electric four-wheelers, electric tricycles and electric scooters according to the number of tires and structural types; According to power sources: pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles and fuel cell vehicles.
According to the power supply mode, it can be divided into two categories. One is to connect an external power supply to get power, and the other is to use fuel cells and energy storage devices (such as energy storage batteries and supercapacitors) as power.
