With the continuous call for global sustainable development, environmental protection and energy conservation have become the theme of the times. Low-carbon and low-consumption means of travel have become the darling of people all over the world in the new era. In response to the times, electric vehicles developed rapidly and quickly became popular all over the world. Today, Cheng Cheng Xiaobian will talk to you about the relevant knowledge of electric bicycles.
Electric bicycle is a kind of vehicle that uses a battery as an auxiliary energy source on the basis of ordinary bicycles, and is equipped with motors, controllers, batteries, handlebars and other control parts and display instrument systems. As a necessary means of transportation, electric bicycles are more convenient, environmentally friendly and energy-saving than traditional bicycles. However, while electric bicycles provide convenience to various families, they also bring various unsafe factors. Due to the uneven manufacturers and the unsatisfactory rationing used, it may lead to the "disease" of the e-bike on the road, bringing various hidden dangers. The implementation standard for electric bicycles is "GB 17761-2018 Safety Technical Specifications for Electric Bicycles", which is a mandatory standard.
This standard stipulates the main technical requirements and corresponding test methods for the vehicle safety, mechanical safety, electrical safety, fire performance, flame retardant performance, radio disturbance characteristics and instruction manuals of electric bicycles.
In terms of vehicle safety, the speed limit, braking performance, vehicle quality, pedal riding ability, as well as the size limit and structure of the vehicle are regulated, among which it is worth noting that the standard stipulates that the vehicle mass of the fully assembled electric bicycle should be less than or equal to 55kg.
In terms of mechanical safety, the vibration and impact strength of the frame/fork assembly, the bending strength and safety lines of the handlebar and saddle rails (in models with such components), as well as reflectors, lighting and horning devices, are regulated.
Electrical safety, the wire wiring installation, short circuit protection, electrical strength and other electrical devices, brake power-off function, overcurrent protection function, anti-runaway function, motor rated continuous output power and other control systems, as well as charger and battery related performance are stipulated.
In addition, the standard also stipulates the fire performance, flame retardant performance, and radio disturbance characteristics of electric bicycles, and standardizes the content and form of product instruction manuals.
Cheng Cheng's conclusion: As of December 2022, the social ownership of electric bicycles in China has reached 350 million, with an annual output of more than 35 million, ranking first in the world, and the output of electric bicycles of more than 1,000 yuan continues to grow. When consumers buy electric bicycles, they must be optimistic about the brand, motor, battery and tires, and consider the braking system to confirm the quality and safety of the product.
