Most of the fire accidents of electric bicycles are related to illegal assembly and refitting and nonstandard parking and charging. So, what is the behavior of assembling, adding and refitting electric bicycles? Can I replace the original 48V battery with 60V or above? How do consumers choose and buy electric bicycles correctly? How to operate electric bicycles according to law?
A: Article 9 of the measures of Shanghai Municipality on the administration of non motor vehicles stipulates that units and individuals are prohibited from engaging in the following acts:
（1） Assembling non motor vehicles
（2） Install power device, awning, seat and high decibel sound on non motor vehicles
（3） Replace the power plant of non motor vehicle or change the size of exhaust device
（4） Dismantle or modify the noise reduction, speed limit and exhaust gas treatment devices of non motor vehicles
（5） Other installation and refitting behaviors that affect the traffic safety of non motor vehicles.
Neither consumers nor sellers are allowed to assemble, install or refit electric bicycles, or sell or use them. Otherwise, they will bear legal liabilities.
A: operators often change 48V batteries into 60V or higher voltage batteries according to users' demands for fast running and long endurance. However, the current "safety technical specification for electric bicycles" (GB 17761-2018) stipulates that the nominal voltage of the battery should not be greater than 48V.
According to the regulations of Shanghai Municipality on the administration of non motor vehicles, replacing batteries greater than 48V is an act of retrofitting or refitting, and driving an electric bicycle equipped or refitted on the road is a road traffic offence and will be punished by the public security organ in accordance with the regulations.
A: there are lead-acid batteries and lithium batteries for electric bicycles. Lead acid battery is not easy to cause fire explosion and other extreme accidents, but it is bulky and small capacity. Although the lithium battery is light, it is easy to explode and fire due to extrusion, puncture and high temperature. Consumers should carefully check whether the battery information on CCC certificate and conformity certificate of electric bicycle is consistent with battery information.
A: No. Consumers should use the original charger or charger matching with battery voltage and other parameters. Never mix different types of chargers. Even if the quality of the charger that does not match the battery parameters is qualified, it may bring fire hazard.
A: first, we should recognize the 3C logo. Consumers should carefully check whether the vehicle has 3C mark in the purchase process, and do not buy products with unclear or no 3C mark.
Second, compare the vehicle information. Read the manual carefully, scan the two-dimensional code on the vehicle certificate and compare the information with the actual vehicle. The key point is to check whether the battery, charger and other key parts are consistent with the CCC certificate and certificate information, and whether the supporting accessories are complete.
Third, we should purchase through regular channels. It is necessary to select merchants with complete licenses, high market reputation and stable business status to purchase vehicles, and pay attention to asking for valid bills and keeping them properly.
A: first, pay attention to charging safety. Do not pull the wire privately or charge in the indoor or corridor, but try to charge in the safe charging place with short circuit protection, automatic alarm and other functions.
Second, avoid overcharging. Avoid long charging time, which should not exceed 10 hours in principle.
Third, pay attention to check the battery condition. It is recommended to go to the professional maintenance point for inspection every half a year to one year. In case of battery bulge and wire aging, it should be replaced in time.
A: dealers should operate in accordance with the law and be responsible for the sales of electric bicycles.
First, it is necessary to hold a business license and operate in the sales place.
Second, it is necessary to strengthen the inspection of incoming goods, take the initiative to ask for the manufacturer's license, 3C certificate and other materials, verify the product qualification certificate, test report and other marks, and purchase in strict accordance with the battery and charger model specified in the agreement signed with the electric bicycle enterprises.
Third, it is necessary to establish a standing book for purchase and sales, record the information of batteries and chargers for each electric bicycle, and keep relevant bills.
Fourth, it is necessary to undertake the responsibility of "Three Guarantees" after sales, timely accept and handle consumer complaints, and safeguard the legitimate rights and interests of consumers.
Fifth, it is necessary to strengthen the awareness of law-abiding. It is strictly prohibited to sell "three noes" electric bicycles and their accessories, to sell electric bicycles without 3C certification certificate, and to assemble, install, refit or assist consumers in assembling, installing and refitting electric bicycles.
