Unannounced visit to the chaos of electric vehicle refitting: can you go on the license plate before refitting? Some manufacturers set up "back door" to leave speed regulation code
2021-10-26
The new regulations on the registration and licensing of electric bicycles in Guangzhou will be implemented soon, and the electric bicycles that meet the relevant conditions will be registered and managed. To be licensed, the first must be the new national standard electric bicycle. However, in recent days, Nandu reporter secretly visited the chaos of electric vehicle refitting and found that many electric vehicle stores provide electric vehicle refitting services, saying they can "soft solve" and "hard solve" the "speed" of the new national standard electric vehicle. In the face of the new regulations on the licensing of electric bicycles in Guangzhou, the offline electric bicycle store simply suggested "licensing first and then refitting", saying that after the licensing, you can go to the store to "speed regulate". Reporter unannounced interview: some businesses suggest "first license plate and then modification" Guangzhou is about to license electric bicycles. In this regard, the Nandu reporter interviewed a number of takeout riders who admitted that they had used or were using modified electric bicycles. Most of them are still lucky, "the licensing and control of electric bicycles will not make it difficult for special travel groups such as takeout workers". However, some riders told reporters that they had just purchased and completed the modification of electric vehicles, and were not sure whether they could be licensed in the future. "It cost more than 5000 yuan to buy a car and modify it. To tell the truth, they were also worried about whether they could be licensed". However, in order to attract customers, some businesses give the suggestion of "putting on the license plate first and then refitting". In mid September, Nandu reporter secretly visited an electric car store on Guangxin Road, Huangpu District, Guangzhou. The instructions for each type of electric bicycle sold in the store say "the speed limit is 25km / h", but the clerk told reporters, "it can be adjusted. At that time, just change it for you on the mobile phone, and then transfer it back to you when you get the license plate. You can also adjust it yourself. It's very simple, just a code." In early October, the reporter made an unannounced visit to Dongpu Road, Tianhe District. In an electric car store, the reporter mentioned that when an electric bicycle meeting the new national standard reaches a certain speed per hour, it will generally sound an alarm. The store told the reporter that the preset speed per hour must be unlocked before removing the alarm. For the implementation of the new regulations on the licensing of electric bicycles in Guangzhou, although the store stressed that the modified electric bicycles may be seized by the traffic police, it finally suggested that "it's OK to unlock them when they are licensed". The electric car store suggested that the reporter wait until the time to license and then unlock. Some manufacturers have reserved the secret code for the speed regulating rear door, and the used car maintenance points are more "hard solution" During Nandu's unannounced visit, the owner of an electric bicycle store told reporters that there were "soft solutions" and "hard solutions" to the speed limit of electric vehicles. "Soft solution" is generally not obvious to increase speed and increase endurance. If it cannot meet the requirements of modification, it must be "hard solution". So, what are "soft solution" and "hard solution"? Nandu reporter found that the so-called "soft solution" is to use the "decoder" or a series of "secret codes" to modify the speed limit program of the onboard chip to achieve the purpose of modification. The reporter further investigated and found that different electric vehicles have different "decoding" steps. Some electric bicycle manufacturers will preset the "back door" program, and the speed limit can be unlocked as long as the "secret code" set on the front. After "decoding", the speed of a new national standard electric bicycle with a speed limit of 25km / h can be increased to more than 40km / h. Nandu reporter noted that as early as June 2016, Guangdong Provincial Public Security Department, Guangdong Provincial Administration for Industry and Commerce and Guangdong Provincial Bureau of quality and Technical Supervision jointly issued the notice on strengthening the management of electric bicycle controllers, pointing out that some electric bicycle models were found to use controllers equipped with speed limiting devices, and preset plug-in, plug-in Cut off the line, and even through some combination of braking and turning handle to unlock and other cheating methods, so that the speed limiting device fails to improve the speed. This preset cheating method is that the electric bicycle manufacturer leaves the "back door" for "soft solution". The "hard solution" mainly includes changing the battery, changing the circuit ("controller"), changing the motor, etc. generally, it can significantly increase the speed or increase the endurance capacity, but the price of "hard solution" is more expensive than that of "soft solution". The staff of Guangdong bicycle and Electric Vehicle Industry Association told Nandu reporter that the so-called "soft solution" speed change is mostly debugged on the controller, and the upper limit of speed increase will be different according to motor power and battery parameters. The so-called "hard solution" often occurs in used car maintenance points. Speed increase is most related to motor power and battery capacity. Nandu reporter inquired about the new national standard of electric bicycles and found that the new national standard requires that the software and hardware of electric bicycles must have tamper proof design to prevent unauthorized modification or modification of the maximum speed, power, voltage and pedal riding ability. At the same time, there must be tamper proof settings for batteries. Relevant personnel of Guangdong bicycle and electric vehicle industry association said that there can be measures to prevent unauthorized changes in speed and other functions at the production design level. Strengthening the supervision at the production enterprise level and increasing sampling products can reduce some illegal practices. Industry Association: there is a risk of combustion and explosion after electric vehicles are refitted with unknown batteries Relevant people of Guangdong bicycle and electric vehicle industry association believe that changing the power system of electric bicycle may change the design balance of the whole vehicle, and too high speed may also increase the risk factor during driving. If the modified electric bicycle changes the charging and discharging mode of the battery, it may cause a variety of problems, including battery explosion and so on. It is estimated that about 70% of the existing electric vehicles in Guangdong use lithium batteries and 30% lead-acid batteries. The two power batteries have their own advantages and disadvantages. The service life of lithium battery is longer, but the battery cell assembly enterprises are uneven, and unsafe products may appear. The above people suggested that, on the one hand, the relevant competent departments should continue to strictly investigate the electric bicycle products that do not meet the new national standard, on the other hand, as consumers, they should also buy the electric bicycle with CCC certification, do not refit it without permission, and do not use the charger not originally distributed for charging. Relevant departments: continue to check and rectify the illegal modification of electric vehicles Nandu reporter inquired that in March 2019, the General Administration of market supervision, the Ministry of industry and information technology and the Ministry of Public Security jointly issued opinions on strengthening the supervision of the implementation of national standards for electric bicycles, which required that after the implementation of the new standards, local market supervision departments should strengthen the supervision and inspection of the sales links of electric bicycles, and severely investigate and deal with illegal sales that do not meet the new standards Electric bicycles without CCC certification, as well as illegal modification, assembly and tampering with electric bicycles. The reporter noted that from March 15 to April 15 this year, the market supervision department of Guangzhou launched a special action to crack down on the production and sales of illegally modified electric bicycles. In an interview with the media, the person in charge of Guangzhou market supervision bureau said that at present, the refitting of electric bicycles mainly includes the following situations: tampering with the speed to make the speed exceed 25 km / h; The type and capacity of modified batteries, and the number of batteries added by modifying the vehicle body structure; Tamper with motor and other power devices. The municipal market supervision bureau said that if the general public are suspected of producing and selling electric bicycles without CCC certification mark, assembly, illegal installation and modification, they can call 12315 and 12345 hotlines to complain and report. The market supervision department will investigate and deal with them according to law and implement the reporting reward system. Nandu reporter also noted that in July this year, the Guangzhou traffic police said at its press conference that they would cooperate with the municipal market supervision department to strictly investigate the illegal modification of electric bicycles, and continue to carry out inventory and rectification against the situation that "modification function", "battery installation position" and "one key switching speed setting" are reserved for electric bicycles when they leave the factory.
