The development of new energy vehicles is a new development in the automotive sector. From a technical point of view, gasoline and diesel are no longer used. Instead, new energy sources are used as alternatives. This puts forward new technical requirements for the design of vehicles from the technical point of view for different new energy sources. At the same time, it alleviates the problem of energy consumption pressure and reduces the environmental pollution caused by vehicle exhaust emissions. It is also better than traditional cars from the environmental point of view. This paper elaborates on the background of the reasons for the emergence of new energy vehicles, the corresponding technological changes, the global development achievements and problems, and the feasibility recommendations.
In recent years, governments around the world have strongly supported the development and application of new energy, and have introduced a series of policies to support the development and manufacturing of new energy vehicles. Various countries have been raising and preparing strategic plans for new energy vehicles, and the national treasury has given a lot of support and subsidies to the initial pilot of new energy vehicles, striving to implement the goal of replacing traditional vehicles with new energy vehicles as soon as possible. With the support of these supportive policies, the global automotive industry and related experts in new energy research and development have responded to the call to increase scientific research, but from a practical point of view, the development of new energy vehicles is still hampered by many obstacles, and only by solving these outstanding problems can the industrialization of new energy vehicles be realized.
New energy vehicles refer to the use of non-conventional vehicle fuels as a power source (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and drive advanced technology, the formation of advanced technical principles, with new technology, new structure of the car. New energy vehicles include five categories, namely hybrid vehicles (HEV), pure electric vehicles (BEV, including solar vehicles), fuel cell vehicles (FCEV), hydrogen engine vehicles, other new energy (such as high-efficiency energy storage, dimethyl ether) vehicles, etc.. Among them, hybrid vehicles, pure electric vehicles and fuel cell vehicles are all electric vehicles.
At present, countries have strengthened their independent research and development under the organization and call of the government, borrowed the global advanced and mature research and development experience and technology, tackled the key technical problems in new energy vehicles, upgraded the production of fuel, battery and other aspects, as well as the technical requirements of increased driving range distance, absorbed creative talents, and improved the performance of new energy vehicles.
However, there is still a huge shortage of new energy vehicle personnel related to new energy vehicle equipment. In this regard, countries around the world have started to establish new energy vehicle teaching laboratories and procure hybrid and electric vehicle training equipment to achieve rapid manufacturing and development of new energy vehicles.
Hybrid and electric vehicle training the focus of future development began to receive attention from countries around the world. From the current development of advanced countries in the production of new energy vehicles, the popularity of 5G and 6G research have begun to bear fruit, and the future of networked vehicles will be tightly bound to new energy vehicles. Therefore, Hybrid and electric vehicle training the focus of future development must be how to make the new energy vehicles can be self-driving, can be connected to the home, comfortable intelligent networked cars.
Driverless is expected to achieve L3+.
The car network includes not only driverless, but also new technologies such as remote control driving and formation driving. regardless of the top brands or companies such as Tesla, Audi, Cadillac, Mercedes-Benz and BMW, the level of driverless is not more than L3. this is in addition to policy regulations, infrastructure, road complexity restrictions, there is also the limitation of communication technology. In terms of delay, 5G delay while 4G is 30-70 ms, for 120km/h high-speed car, 30ms delay corresponds to an increase in braking distance of 1m, but for 1ms delay, the braking distance is only 3.3cm, which is a fatal gap for emergencies. 5G low latency, high reliability features will further promote driverless towards the level of L4, but also contribute to the development of technologies or scenario applications such as car and cloud, car and car interconnection, and car and peripheral mall interconnection.
Automotive intelligent manufacturing helps to upgrade the industry.
Both Made in China 2025 and Industry 4.0 are inseparable from the concept and technical support of the Internet of Everything. As a representative scene of intelligent manufacturing applications, automobile manufacturing will also be a testing ground for the realization of Made in China 2025 or Industry 4.0, and the technical characteristics of 5G can cater to the needs of these scenes and will become the cornerstone of the development of automotive intelligent manufacturing.
Wireless charging for automobiles will be developed rapidly.
Just as wireless charging for cell phones will become the standard for 5G phones, wireless charging for cars is likely to become the standard for 5G cars in the future. Wireless charging piles and cars will be supported by 5G technology to achieve the interconnection of things.
A strong charging network cannot be achieved without a distributed feeder automation system, whose advantages include reduced O&M costs and increased reliability. Feeder automation systems need to be supported by ultra-low latency communication networks
Automotive wireless healthcare will become possible.
With 5G connectivity to AI medical assistance systems, the healthcare industry has the opportunity to carry out personalized medical consultation services. AI medical systems can be embedded in hospital call centers, home medical consultation assistant devices, local physician clinics, and even mobile clinics that lack on-site medical staff.
With the application of 5G technology, the car will become a mini-clinic, with various sensors implanted in the seat and steering wheel that can identify health risks of the driver and passengers in advance and give timely diagnostic advice. In addition, the car's failure can also be diagnosed and "treatment" through wireless, greatly reducing the cost of car repair and time costs.
The car entertainment system will be completely upgraded.
By August 2016, there will be nearly 10 million 4K/UHD TV subscribers worldwide. Lower prices and new service subscription models are predicted to enable half of the world's TV viewers to use 4K/8K TVs by 2020. 8K video has bandwidth requirements in excess of 100 Mbps and will require 5G WTTx support. Other video-based applications (such as home monitoring, streaming and cloud gaming) will also benefit from 5G WTTx, such as current cloud gaming platforms, among others.
The scenario of the car becoming a mobile entertainment facility will be realized with 5G technology support, allowing passengers to download movies, watch movies, sing Karaoke, play games and travel at high speeds in the car for complete entertainment.
Smarter car logistics.
5G will provide opportunities for wearable and smart assistive devices in both the consumer and enterprise business sectors. Wearables will provide "hands-free" information services for manufacturing and warehouse workers. Cloud-based AI will enable wearable devices with AI capabilities, such as searching for specific objects or people.
These will be the focus of Hybrid and electric vehicle training the future development, the first of which is the need for automotive education equipment manufacturers to develop automotive education equipment that meets the needs of the new automotive workforce. In this regard, Guangdong Zhongcai Education Equipment Co., Ltd. has already started and developed several sets of new energy teaching aids. For example, Beiqi New Energy six sets, BYD E5 color screen five sets, electric drive system training table and other new energy series teaching aids, etc. Guangdong Zhongcai Education Equipment Co. It has been purchased and recognized by various colleges and universities, vocational colleges and automobile maintenance enterprises worldwide.
