Electric car technology is not without faults.
Associate Professor, Dr. Dam Hoang Phuc (Hanoi University of Science and Technology) explained that after the recent horrific mini apartment fire in Hanoi, the authorities have not yet made any official conclusions about the cause of the fire, but people may have seen electric motorbikes in the area of the scene, so they assumed that they were the culprit. And in recent days, somewhere in the apartment buildings, there has been a spontaneous ban on this type of vehicle. "Acts of absolutely banning electric vehicles, in my opinion, are extreme. Because the solutions proposed must be based on a technical perspective as well as a comprehensive view of the problem. It is also an action following the long-standing habit of many people, which is to completely ban them whenever there is a risk," Mr. Phuc commented.
Electric vehicles are the advancement and development trend of the future.
According to Dr. Phuc, from European countries to the US and China, all are promoting the development of electric vehicles as well as electric public transport. Vietnam is also following the trend of integration, technology development and gradually electrifying road vehicles. This is an inevitable trend. However, it must be admitted that in Vietnam there are still some problems that need to be improved. Specifically, there are still substandard products on the market, and many people even "modify" or change the structure of the vehicle, which causes potential dangers to the community and to consumers in general. "Seeing this, we can have solutions to limit and prevent poor quality vehicles that do not meet inspection standards from appearing on the market. This is both to ensure safety for the community and to protect the rights of consumers, ensuring equality for serious and reputable manufacturing enterprises," said Mr. Phuc.

From Germany, Mr. Nguyen Minh Dong, an expert on engines and emissions testing, shared: "In Germany, electric vehicles are also charged indoors, but there has not been a single case of an electric vehicle catching fire. The problem is not a fault in the electric vehicle technology. The key here is the inspection process. In Germany, any product that uses electricity is strictly and scientifically inspected in all situations of impact, load, flooding, etc. If the inspection process is done firmly, electric vehicle technology is not a high risk of fire and explosion."
In fact, currently in the world, there are not only a few brands specializing in producing electric vehicles such as Tesla (USA) or Vinfast (VN), but most car brands are investing and focusing on the electric vehicle segment because this is the future of the auto industry. Recently, although the Chevrolet car brand had to recall all Bolt electric cars produced in the period 2017 - 2022 due to the risk of fire and explosion, in reality, there were only 5 fires in nearly 142,000 cars on the market.
Ban electric cars, refrigerators, air conditioners...?
The most important part of an electric vehicle is the battery, which is often mistakenly thought to be the cause of a car fire. However, experts say the technology used in electric vehicle batteries is specifically designed to ensure safety. Unlike gasoline, which ignites immediately when exposed to a spark or flame, lithium-ion batteries need time to reach the necessary heat to ignite. Meanwhile, the battery system in an electric vehicle is protected by a thick layer of metal to minimize the risk. Furthermore, the battery pack in an electric vehicle is a collection of countless separate modules, each with its own "fuse" system to cut off power to each part, helping to reduce the risk of fire or explosion.
Dr. Nguyen Duy Khiem, an expert in electromagnetism at Quy Nhon University (Binh Dinh), emphasized: As fossil fuel sources are increasingly depleted, the development of renewable energy to replace them is an inevitable trend. Accompanying this trend are new devices, the most prominent of which in recent years is electric vehicles. In general, everything has risks, but according to the logic of development, the following inventions will have a higher level of safety. If people are worried about the insecurity of electric vehicles or batteries, then electric vehicles will be safer.
Gasoline cars also have gas tanks that can hold up to several dozen liters, which are high-risk subjects. According to him, we should not react without objective basis because of some incidents without clearly considering the cause of the problem. "The cause of unsafe equipment in general is mainly due to the way we use, operate, and even maintain it. For electrical equipment, I find that problems are often caused by the power line or socket. When we insert and remove it frequently, it is easy for the socket and the plug of the device to no longer stick together during the charging process. This causes electrical energy to be lost and converted into heat energy, leading to damage and safety risks over time," Dr. Khiem explained.
According to the Vietnam Association of Motorcycle Manufacturers (VAMM), there are currently about 4 million electric bicycles and motorbikes in circulation in the country. According to Motorcycles Data, electric motorbikes in Vietnam will have the second highest growth rate in the world, after China, in the near future. The Ministry of Transport's green energy conversion program, carbon and methane emission reduction, also aims to have 100% of road vehicles, including personal vehicles, public transport vehicles, and specialized vehicles, converted to electricity and green energy by 2050.
Mr. Pham Tuan Khoi, General Director of Hanh Trinh Xanh Company, a business operating strongly in the community sector, shared: The current general trend in countries around the world as well as in Vietnam is to increase green technology, reduce waste and emissions, and build healthy communities. According to the Ministry of Industry and Trade, sales of electric motorbikes in Vietnam have increased by about 30 - 35% in recent years, making Vietnam the largest electric motorbike market in ASEAN and the second largest in the world, after China. "If we talk about risks, gasoline vehicles can also cause fires. Or phone chargers, induction cookers or refrigerators can also catch fire... If we ban electric vehicles, should we ban all those items?", Mr. Khoi raised the issue and added: "Vietnam, like many other countries, is applying policies to encourage people to switch to electric vehicles. The problem here is to control poor quality and uninspected vehicles. In addition, we must plan and arrange separate, safe charging areas for electric vehicles, not ban electric vehicles."
According to Autoinsuranceez 's synthesis of data from the National Highway Traffic Safety Administration (USA), data updated in November 2022 showed that the rate of electric vehicle fires was only 25.1 per 100,000 vehicles, compared to 1,529 per 100,000 internal combustion engine vehicles. In other words, the number of gasoline vehicle fires and explosions was 61 times higher than that of electric vehicles.
