Safety is the lifeblood of the energy-saving and new energy automobile industry

it has been less than a month in 2017, and the policy dividend document expected by the energy-saving and new energy automobile industry after years of hard research and development has not yet been implemented, but there are "gold medals" related to safety. It seems that the author is biased to say so. However, under the background of large production and marketing in 2015 and cheating on subsidies, the frequent fire accidents of lithium battery plants and electric vehicles in 2016 seem to be the main reason for the "mistiness" and "wait-and-see" of the current policy. The stagnation of production and sales of individual models seems to indicate that the industry is currently strongly dependent on policies. At present, from the perspective of enterprises and investors, how to treat the energy-saving and new energy automobile industry is a very important issue, which is directly related to the self-interest of relevant enterprises, the development of the industry and even the transformation of the whole industry

first, energy saving and new energy vehicles are the general trend. Just as carbon fiber composites and 3D printing technology will have a huge impact on the automotive industry, the auto companies that do not do well in energy-saving and new energy vehicles will be eliminated. The latest progress in relevant fields at home and abroad indicates that the four major process assets as the core of traditional automobile enterprises are facing the risk of impairment in the future. Just like you are still making molten bombs against tanks, other people's tanks are already in carbon fibrosis. Past historical experience has proved that it is inevitable to be passive if we do not do a good job in technical reserves. We are at the forefront in many fields, but as an energy-saving and new energy automobile industry, we still need to stand at the strategic commanding height and make a reasonable strategic layout through vigorously implementing innovation driven development. Energy saving and new energy vehicles are the general trend and the inevitable result of business model deduction under the background of power technology revolution, material technology progress and emerging industries

secondly, energy saving and new energy vehicle technologies are systematic, not isolated and partitioned. In view of the industrial risks faced by the existing technology system, we should give it full attention and in-depth research. We should pay full attention to the existing overall technical route and the development direction of the subdivided fields. History has its tides, and tides have their ups and downs. Standing proudly at the forefront of the tide requires a solid foundation, and the main premise is that the direction is correct. In the current technical field, high attention and vigilance should be paid to the vehicle mounted high-efficiency power generation device, integrated control and power battery technology

in the future, automotive fuel can no longer be transmitted to the wheels by means of mechanical energy output from the heat engine. The fuel can only be generated by on-board power generation. The technology on the vehicle is mainly electric and electric mixing. The question is what kind of technical route to take? What is the highest efficiency of foreign heat engines? How to generate electricity? What kind of technical road should electric hybrid take? Wan Gang, Minister of the Ministry of science and technology, once pointed out that from now on, hybrid power is changing from heavy hybrid to plug-in type, and in the future, the generator with increased program will become a power generation system. There are also two directions for fuel cells. One is to use fuel cells as the main force, and the other is to use fuel cells as the hybrid power source of incremental electricity and electricity. Some manufacturers can only output the maximum force line in these three ways, and eventually become a technical route driven by motors and composed of power generation and storage systems. Its development can concentrate the greatest efforts to overcome the most critical technologies. The government also needs to strengthen infrastructure, scientific research incentives Application of standard testing, laws and regulations promotion, etc. This is also the direction that needs attention

in the future, there will be more fields worthy of comprehensive research. For example, if there is a motor controller with charging function and a bidirectional inverter, what kind of symbiotic relationship will it have with the on-board charger and the charging pile of the charging station in the future; Whether this will change with the current small and comprehensive development of the charging industry to large and comprehensive, the intervention of large power users, the progress of IOT technology, the substantial increase of battery energy density and the change of battery business model; How to evaluate the current trillion scale charging infrastructure construction; How to clarify the relationship between them and property; Whether the business model of power generation - power transmission channel - power selling company - energy service company/charging operator (the property participates in "food sharing"), will be subverted by the business model of new traditional energy Consortium (which may have no relationship with China or South Africa, such as Zhongning Industrial Park) or photovoltaic power generation/DC charging, which mainly focuses on thermal power peak shaving; What is the energy recovery rate of electric vehicles

there are also problems with batteries, including doors, engine covers and luggage compartment covers. It seems that once there is a safety problem with the current electric vehicle, it is the battery or the BMS that can only be managed by weak current. In fact, these are still worth discussing

the safety of the battery is inseparable from the power control system. It is necessary to further study the current on-board energy conversion modes and methods, and study their internal problems in combination with the failure mode and use mode of the battery. In this way, the battery and BMS will not become the target of public criticism on safety issues

some key problems need to be solved in the application of PWM in energy-saving and new energy vehicles. The technical route of the battery itself is more debatable. In the past, we used to learn too much from Tesla and used 18650 batteries. What we really need to learn is the use of volt or Qichen electric vehicle batteries. The former has not fundamentally solved the safety problem of battery use, while the latter two have not had any safety accidents so far when they sell 200000 or 300000 vehicles respectively

finally, the industrial policy needs to be clear and stable, not unpredictable, predictable, so as to facilitate the investment and financial calculation of enterprises, and finally should be fully market-oriented, so as not to cultivate problem industries. In particular, the carbon emission trading rules of the automotive industry should be set up reasonably. Do not wait for the newly formulated rules to be implemented, but also study the trading rules in the era of no subsidies, resulting in excessive policy fluctuations

enterprises need to attach great importance to a series of policy requirements recently issued by the government and various ministries and commissions. Safety is the lifeblood of the energy-saving and new energy automobile industry. We should have a sense of fear for power battery safety accidents and be responsible for consumers. Only in this way can the whole industry have a future
