The development trend of electric vehicles in the future.Battery capacity breakthrough and safety are the key

　　An Uber driverless car accident happened last week, followed by a crash in a Tesla electric car in California. This blue Model X hit the fence and caught fire. The front part of the whole car was completely Damaged and the driver died after being sent to hospital. Although accidents involving man-driving and gasoline vehicles often break out, the electric vehicle accident will not have much impact on the industry's wind direction. However, the use of high-density batteries may make cars more likely to catch fire or even explode. The occurrence of this incident has sounded the alarm for the electric vehicle industry, and automakers must seriously consider battery safety issues.

　　Although accidents often occur in human driving and gasoline vehicles, the electric vehicle accident will not have much impact on the industry's wind direction. However, the use of high-density batteries may make cars more likely to catch fire or even explode. The occurrence of this incident has sounded the alarm for the electric vehicle industry, and automakers must seriously consider battery safety issues.

　　Battery capacity breakthrough and safety are the key

　　Electric vehicles have become the trend of future cars, but the battery problem is still a pain point in the industry. Most traditional electric vehicles use lead-acid batteries. Although lead-acid batteries perform well in low-temperature environments and are quite cheap, they put drivers at risk.

　　The main reason for the low price of lead-acid batteries is that they are recyclable, but this may cause some other problems. Lead poisoning incidents have been reported from time to time, and unsafe methods for recycling may further affect the health of workers. Lead is debilitating or even fatal, and strict practices may increase costs.

　　Some car manufacturers have turned to lithium-ion batteries. Although they are currently expensive, lithium-ion batteries are lighter and can store longer power, which is very suitable for electric vehicles. However, lithium-ion batteries still rely on a limited supply of rare earth metals, which may also cause worker injuries and environmental damage? Therefore, if electric vehicles will become popular, what we really need is a new type of battery.

　　At present, there are many alternatives to batteries. Projects such as solid-state batteries, supercapacitor fast charging, and batteries that only run on carbon and water are attracting attention. Venture capitalists have invested $1 billion in 2018 to advance next-generation battery technology. However, these battery concepts are not mature enough to even power products such as electric vehicles. Experts believe that advanced batteries are one of the biggest demands, and various technologies currently need breakthroughs.

　　Electric cars are cheaper than gasoline cars

　　The importance of green environmental protection has gradually been realized by people. The relevant emission restriction policies have become more and more stringent, and electric vehicles are becoming the focus of the world. France and the United Kingdom have announced that they will ban gasoline vehicles before 2040. China is promoting the development of the electric vehicle industry, which means that China will also ban the use of fuel-guzzling vehicles in the near future.

　　Lithium-ion batteries are an important part of electric vehicles in the future. Analysts believe that their prices will become cheaper and cheaper, leading to lower prices for electric vehicles. However, although the global electric vehicle revolution is coming, its timetable may not accelerate too much.

　　The key point is that the cost of electric vehicles is lower than that of fuel-burning vehicles, which means that the cost of battery packs needs to continue to fall, but the analysis believes that the price of lithium batteries and other components may increase in the future. Of course, it is still possible to reduce costs through mass production.

　　Today’s gasoline cars don’t have to worry about running out of fuel wherever they go, and electric cars have not yet reached such conditions. Sufficient power grid is a prerequisite for electric vehicles to take off. It will take a long time to install charging facilities from cities to towns and even remote villages.

　　Relevant data shows that there are about 16,000 charging piles in the United States, while China will reach about 150,000. This figure shows that China will be the world leader. Beijing plans to advance its charging station network to meet the demand for 5 million electric vehicles by 2020, and China is striving to become a leader in electric vehicle manufacturing.

　　But industry experts believe that if there is not enough power supply in the future, various power curtailments may occur, and increasing the supply of charging points from the existing power grid may cost a lot of money.

　　Innovative application scenarios bring more opportunities

　　With the development of the Internet of Things, artificial intelligence, and 5G communication technology, people's lives are moving towards an intelligent stage, which also brings a bright future to the automotive industry. At present, some companies such as Google and Tesira are conducting self-driving cars on the road. We can imagine that in the future, urban transportation services may be handed over to these autonomous vehicles, and a self-driving car will be a few minutes after the order is placed with Didi. Appears in front of your eyes, you can use it freely without worrying about the driver.

　　In addition, self-driving cars may be used in large quantities for delivery. The transportation of goods in all aspects of the city is a boring job for drivers, and the demand for urban express delivery is increasing. It is most suitable for these tasks to be handed over to autonomous cars. JD.com, Alibaba, and SF Express are all promoting unmanned delivery. JD.com's independent research and development of smart distribution stations has landed in Shaanxi, and delivery services are completed through unmanned vehicles and unmanned distribution stations. The future urban logistics system may be assisted by automated vehicles, unmanned vehicles, and drones.

　　Ford has launched an automatic driving police car for traffic management. This kind of car can monitor illegal parking, speeding and other unsafe behaviors. If illegal behavior is found, it will automatically track and impose corresponding penalties on the owner. With the continuous growth of urban vehicles, autonomous police vehicles can reduce the burden on law enforcement officers. Ford's automated police car uses AI technology to take photos and analyze location information of the offending vehicles. This method can make up for the lack of human tracking and help further reduce traffic accidents.

　　The application scenarios of electric vehicles are constantly innovating. In addition to the aforementioned, there are shared automobile industry, sanitation vehicles, port and terminal transport vehicles, etc. These new application scenarios will further promote the development of the electric vehicle industry.
