the reporter learned from the ministry of industry and information technology that on september 19, the ministry of industry and information technology, together with the ministry of public security, the ministry of emergency management and other departments, publicly solicited opinions on the latest revised "electric bicycle safety technical specifications". compared with the current standards, this "new national standard" has higher requirements for the intelligent functions and safety performance of vehicles.

dynamically monitor battery abnormalities and send reminders in time
the "new national standard" first clearly improves fire-retardant performance, improves the flame retardant requirements and test methods of non-metallic materials used in electric bicycles, limits the proportion of plastic parts used, and requires that the vehicle coding should use high-temperature resistant permanent markings to facilitate strengthening of full-chain supervision and fire accident tracing investigation and handling.
secondly, it is to prevent illegal modification. it is clarified that the controllers, batteries and chargers of electric bicycles should have mutual recognition and coordination functions. the anti-tampering requirements are improved from the three aspects of battery packs, controllers and speed limiters to ensure the mutual recognition and coordination between chargers, batteries and controllers. the "one car, one battery, one charger and one code" policy is vigorously promoted to leave no room for illegal tampering.
in order to ensure riding safety, the test methods for the rated power and maximum speed of the motor have been optimized to technically ensure that the maximum design speed cannot exceed 25km/h. at the same time, the torque limit indicator for the motor running at low speed has been increased to allow the motor to temporarily output higher torque to ensure that the vehicle can cope with special conditions such as short-distance climbing and meet the normal riding needs of consumers. it is worth noting that in the description of the main revisions to the "new national standard", it is mentioned that the maximum design speed shall not exceed 25km/h. this is mainly because if the speed is too fast, it will directly increase the probability of traffic accidents. once an emergency occurs, the rider has a short time to make corresponding risk avoidance actions, and the braking distance will also be longer. it is easy to collide with other vehicles or pedestrians. sometimes there will be out-of-control phenomena such as side slipping and falling, causing many personal injury accidents.
relax the weight limit of the whole vehicle. taking into account factors such as the accelerated pace of life of consumers, the expansion of travel radius, and the inconvenience of charging in recent years, the weight limit of lead-acid battery models will be appropriately relaxed. the weight limit of vehicles using lead-acid batteries will be relaxed from 55kg to 63kg, which will help meet consumers' needs to increase cruising range and reduce charging frequency.
add beidou positioning and real-time communication functions, requiring vehicles to have beidou positioning and dynamic safety monitoring functions, and improve the product information level and safety risk prevention capabilities. the beidou positioning module can record the current longitude, latitude and other information of the electric bicycle, and provide real-time feedback to users through the communication module. once theft occurs, it can effectively help consumers find the vehicle as soon as possible; the dynamic safety monitoring function can send consumers the abnormal driving status of the vehicle and the battery voltage, current, and temperature that exceed the normal range in a timely manner, reminding consumers to identify and deal with abnormal safety issues and eliminate safety hazards as soon as possible.
the "new national standard" also adds the following content: "in order to ensure driving safety, electric bicycles are encouraged to install rearview mirrors" and rearview mirrors are not included in the width of the vehicle. considering that some lighter electric-assisted vehicles generally do not install rearview mirrors, in order to respect the design habits of these products, this draft for comments does not make the installation of rearview mirrors a mandatory requirement, but manufacturers can decide whether to install them according to the needs of the vehicle model.
in addition, it is no longer mandatory to install a pedal-based riding device. instead, manufacturers are allowed to decide whether to install a pedal-based riding device based on the design requirements of the vehicle model. this will help save production costs and provide consumers with more vehicle model choices.
technology and security face new challenges, and companies need to increase investment
an electric bicycle industry insider in nanjing analyzed that for some small and medium-sized brands and local brands, the technical research and development capabilities and financial strength are relatively weak. after the "new national standard" is revised, they may face greater pressure in meeting the new technical standards and safety requirements. for example, in the application of fire-retardant materials, the improvement of motor performance, anti-tampering technology, and the realization of positioning communication technology, more resources may need to be invested in technical upgrades and transformations. if the requirements of the "new national standard" cannot be met, there may be a risk of being eliminated from the market.
according to the official website of the ministry of industry and information technology, in order to further listen to opinions from all sectors of society, the draft standard for soliciting opinions is now publicized, and the deadline is october 19, 2024.
