There are still 3 days! Starting from November 1st, electric bicycles exceeding the standard are prohibited from being used on the roads in Beijing. The million-dollar electric vehicles that shuttle through the streets and alleys of Beijing are undergoing a tremendous change. The three-year transition period will end. According to regulations, from November 1st, there will be only white-licensed electric vehicles on the road: pedals, speed limit below 25km/h, complete vehicles below 55kg, and battery voltage not exceeding 48V.
However, with the frequent occurrence of electric vehicle safety accidents, there is still a gap between compliance and safety-private modification faces the dilemma that it is difficult to supervise. Some people take risks in the name of convenience and let compliant cars quietly “exceed the standard.”
In 3 days, the orange card expiration is approaching
“Speed limit” is the biggest controversy, it is to shorten the braking distance.
Ms. Jin bought an “extra-standard electric car” last year. “Actually, the new national standard had already been implemented at that time, but I was lucky. I bought the big orange car because it was more comfortable and could run far. But now the New Deal is about to land and I have to change the car. I bought a car for several thousand yuan. It can only be sold for a few hundred dollars, and it is a loss. I am worried that the traffic police will find that the car will be detained and lose money, so I can only change it.”
The orange number plate is eliminated and the white number plate is updated. The legal basis is the “Beijing Non-motorized Vehicle Management Regulations” that came into effect three years ago. The “Regulations” clearly stipulate that electric bicycles produced and sold in Beijing shall meet national standards. Electric vehicles that do not meet the national standards will be given a three-year transition period and have an orange number plate. After the transition period has expired, they will not be allowed to drive on the road.
The three-year transition period will expire on October 31 this year. A reporter from Beijing Commercial Daily learned from the Municipal Traffic Management Bureau that after November 1st, the police will first detain the vehicle and then fine the vehicle if an excessive electric vehicle is on the road.
The new national standard requires that the mass of the electric bicycle (including battery) should not exceed 55kg, the maximum speed should not exceed 25km/h, an alarm should be given when driving over 15km/h, the motor power should not exceed 400W, and the nominal battery voltage should not exceed 48V. Electric bicycles that do not meet the standards are regarded as electric mopeds or electric motorcycles, and require a driver’s license, insurance, and limited travel areas.
It is worth mentioning that the new national standard is a mandatory standard for the full text. Safety is placed first in the new national standard.
Regarding the most controversial “speed limit”, experts explained that the speed limit can shorten the braking distance, give car owners enough reaction time, and avoid accidents to the greatest extent. If accidents cannot be avoided, the hazards of impact can also be reduced. The speed limit of 25 kilometers per hour is a safe speed after testing.
The new national standard was officially implemented on April 15, 2019. According to statistics from Jiangsu Province, within one year of the implementation of the new national standard, the number of electric bicycle accidents and deaths in the province dropped by 3.3% and 11.77% respectively year-on-year.
Tamper proof? Can decode!
You can see in more than one “Strategy”, “Play the card first, then you will understand.”
Under the new national standard, the cost of electric vehicles has increased, but the mileage and speed have decreased. Safety hazards in real lifeNakadoriOften ignored by consumers. Therefore, many car owners set their sights on modification.
In fact, according to the new national standard, the software and hardware of electric bicycles should have a tamper-proof design to prevent unauthorized modification or alteration of the maximum speed, power, voltage, and pedaling ability. Ms. Chen, the boss of an electric car dealer, told reporters that brand electric vehicles are generally more compliant, and many car manufacturers have tried to use technical means to prevent electric bicycle modification.
But from the actual situation, the anti-tampering design is useless. A reporter from Beijing Business Daily saw in more than one “Strategy”, “It is recommended to get a white card first, then refit”, “You get the card first, and then you understand.”
At a brand electric car shop in Chaoyang District, Beijing, when a reporter asked whether the electric car could be speeded up, the owner Mr. Li (pseudonym) said, “I can’t mention it for the time being. Now it is strictly checked. It will be the end of the month.” Another owner of an electric bicycle shop said that speeding up can do it by himself.
Self-modification is not difficult. A reporter from Beijing Business Daily tried to search for “electric car modification” in the video software, and could easily find a large number of teaching videos. “How to modify an electric car if you want to run to 100 yards?” “Replace a small part to easily double the speed” and other content, with tens of thousands of views.
“The structure of electric bicycles is relatively simple, and many parts are easy to open. Car companies and regulatory authorities actually have ways to restrict modification, which will greatly increase the cost of electric bicycles. For example, some key parts of electric bicycles, motors, and speed control If the device is encrypted on the software, then the modification requires a password, which is equivalent to that only the original factory can receive the control signal. This is one way.” Zhang Xiang, a researcher at the Automotive Industry Innovation Research Center of North China University of Technology, told reporters.
The reporter learned that modification can be divided into soft solution and hard solution. The former is to unlock the speed without changing the vehicle hardware, but there is generally an upper limit; for hard solution, the controller needs to be changed, which can be faster and more difficult. Some.
Parts required for modification can also be purchased on the e-commerce platform. After searching on the e-commerce platform, a reporter from Beijing Business Daily found that the price of the decoder is about 150 yuan, the price of the controller ranges from 100 to 500 yuan, and the monthly sales of some products exceed 100.
It is worth mentioning that an e-commerce platform has blocked some keywords. For example, searching for “electric car speed” and “electric car decoder” will not find results, but it is still possible to search for products through similar keywords.
Generally want to increase battery life, 48V changes to 60V in seconds
“If you don’t do it and others do it, then you won’t be able to occupy this market.”
In addition to removing the speed limit by decoding and replacing the controller, increasing the battery life is also the demand of many car owners. In addition to the vehicle’s own attributes, the battery life is also related to the battery.
According to the new national standard, the battery voltage of electric vehicles shall not exceed 48V. A reporter from Beijing Business Daily learned from different car dealers that whether the 60V battery can be replaced depends mainly on the size of the battery pack box. At present, the main electric bicycles on the market have become relatively small models of battery pack boxes, but there are also vehicles that can be used for large and small batteries.
“Some electric vehicle factories may be more standardized and sell complete vehicles with batteries. In order to be more flexible, some electric bicycle factories may allow their dealers to empty the batteries, and the market can replace the batteries.” Linkage Tianyi New Energy Co., Ltd. Li Yulei, director of the marketing department, said in an interview with a reporter from Beijing Business Daily.
Li Yulei said frankly: “When the new national standard was first implemented, it was extremely difficult for each model to be produced and entered into the catalog. Many models that did not meet the standards were not allowed to be listed. However, there will be a bit of transition later, and there may also be sideballs. Exist. In fact, many manufacturers nowadays, 48V and 60V batteries are universal, this is for market competition. For empty cars and cars with 48V and 60V batteries, ordinary people have demand, some manufacturers think that if you don’t do it, others will do it. Yes, then you can’t occupy this market.” Li Yulei said.
The reporter saw in a non-brand electric bicycle store that many electric bicycles do not have original batteries. The owner, Ms. Fan (pseudonym), said: “The battery is not original. The car is made by the manufacturer of the car. The battery is made by the manufacturer of the battery. There is no matching or recommended battery. How big is it for you.”

Financial commentator Zhang Xuefeng told the Beijing Business Daily: “The electric vehicle batteries on the market mainly include lead-acid batteries and lithium batteries. Because lead-acid batteries are large in size and small in capacity, and lithium batteries are small in size and large in capacity, many people will privately use lead-acid batteries. It is converted into a lithium battery without the inspection and supervision of relevant departments. The quality of the batteries on the market is mixed, and the electric vehicles after modification are prone to explosions.”
The reporter searched for “electric vehicle battery” on the e-commerce platform and found that there are many brands and types of batteries to choose from, and some of them can also be installed on-site.
Sun Zhicheng, vice president of Xiaoha’s battery replacement technology, told the Beijing Business Daily that most of the electric bicycles use lead-acid batteries, which poses pollution problems. It can be said that the next two rounds of lithium battery will be the general trend.
“Because of its natural electrochemical activity, combined with the complexity of the charging environment such as battery operating conditions and car battery adaptation during consumption and use, the fire safety problem of two-wheel battery charging still cannot be underestimated. In fact, ordinary consumers In fact, the “safety of batteries” is relatively indifferent in terms of professional cognition.” Sun Zhicheng said.
For example, Sun Zhicheng, “For example, when the battery is charged in a low temperature state, there is a risk of fire and loss of control. Consumers do not know whether the battery is charged in a safe and healthy state. In addition, after the battery is accidentally dropped or bumped Although it can be used on a household electric car, the user thinks it is safe, but the actual internal situation is not understood, and there is no way to make professional judgments.”
Batteries are often the source of major safety accidents such as fires and explosions of electric vehicles. What are the main risks of modifying batteries? The reporter learned from the Beijing Market Supervision Bureau that the original charging and discharging circuit may not meet the current requirements of the large-capacity battery for the modification of the electric motor and the battery.
Due to the higher prices of regular, big-brand batteries, some illegal traders were driven by profits and set up “small workshops” to assemble batteries. Most of these batteries have the phenomena of weak welding between battery cells, chaotic internal wiring, rough wiring, exposed conductive parts, easy overall fixation, and mostly recycled batteries. These batteries have not undergone strict factory inspections, and the product quality is worrying. Such batteries are prone to internal short circuit or thermal runaway, which threatens personal safety.
In addition, once an “exceeding standard vehicle” causes a traffic accident, because some of its key technical indicators exceed the provisions of the electric bicycle standard, and the power performance is significantly higher than other non-motor vehicles, it will be judged as a motor vehicle in judicial practice, which will make driving People bear more responsibility in the identification of accident liability and subsequent compensation.
The reporter learned from the Municipal Traffic Management Bureau that from November 1st, the public security traffic management department will strengthen the special rectification of electric bicycle traffic violations, focusing on investigating and punishing the installation and modification of power devices such as motors and batteries, or replacement of motors and batteries that do not meet national standards. Assembling or refitting power devices such as batteries, dismantling or modifying speed-limiting processing devices.
Drivers who drive assembled or modified electric bicycles on roads shall be fined between 500 yuan and 1,000 yuan; if the circumstances are serious, the vehicles shall be confiscated.
Battery, the biggest pain point
Electric vehicle charging and swapping facilities will soon have industry standards.
Battery safety has always been a pain point in the development of the electric vehicle industry. Providing solutions for safe charging is a must for future development, and this has given birth to the battery swap business.
Recently, a number of electric vehicle swap stations have appeared on the market. At present, outside sellers are the main service targets, such as e-power swap and Xiaoha power swap. Users only need to scan the code to get the battery directly from the battery replacement cabinet without recharging it by themselves. For example, the price of e-replacement is 299 yuan a month, and the deposit is 1,000 yuan.
Three brands of power exchange facilities were installed at the entrance of a community in Changping
The reporter found that there are 48V and 60V batteries in the electric cabinet for e-swap in Beijing. But first you need to go to an offline store to modify the battery car before it can be used. This does not meet the requirements of the Beijing Municipal Non-motorized Vehicle Management Regulations.
A reporter from Beijing Business Daily interviewed E-Motor Technology Co., Ltd., which belongs to e-changing, on this issue. Mr. Wang, the person in charge of Beijing City of E-Motor Technology, told the reporter of Beijing Business Daily that E-Motor Technology has adopted 48V and 60V dual-platform research and development since the early stage of product development. The idea is to replace two batteries in the same cabinet.
“In the future, we will actively respond to and support national calls and policy requirements for 60V batteries on the market, and gradually replace them with 48V. We will conduct unified testing and processing of the recovered 60V batteries, including methods such as echelon utilization, distributed energy storage, etc. In the short term, we will still focus more on serving B-end users such as timely delivery and express delivery. In fact, we have been trying and piloting power exchanges for ordinary people.” Mr. Wang said.
Sun Zhicheng told reporters that Xiaoha’s battery replacement pays more attention to the monitoring of battery use and working conditions through intelligence. For example, a normal battery has four temperature collection points. How about temperature, temperature difference, and temperature rise represent the dimensions of health. The problem of battery safety is centralized to the enterprise for unified prevention and control, which effectively solves the safety of consumers in the use of batteries. There is no problem of perception. “
The reporter noticed that the charging and swapping facilities for electric vehicles are also welcoming industry standards. On October 21, the first electric bicycle charging and swapping technology innovation conference was held in Beijing, and discussions were conducted on the signal that the electric bicycle charging and swapping industry standard is about to be issued.
“The introduction of the centralized charging facility standard will have a great positive effect on future iterations. The number of existing charging facilities, including replacement users, is too small compared to the real user inventory, so this update iteration is very Easy.” Wang Zhenfei, chairman of Shenzhen Mammoth Travel Technology Co., Ltd., told a reporter from Beijing Business Daily.
“Consumers should also pay attention to whether the battery registered on the purchased electric car is on the 3C certification certificate matches the battery of the changer. This is also a very important basis for the future market supervision bureau and traffic police to enforce the law.” Wang Zhenfei said.
A reporter from Beijing Business Daily noted that the “Zhejiang e-line online” digital platform pioneered by Zhejiang in the country was officially launched on October 21. The coded electric bicycles, frame and battery all have a “two-dimensional code ID”, that is, “one car, one electricity, one code”, to further regulate the behavior of electric bicycles in the process of sales, production, sales and maintenance, and to ensure that electric bicycle accidents Traceability. It is expected to be extended to the whole country in the future.
