2015 is over. All major auto companies have achieved good results under the 15-year new energy favorable policy. However, in 2015, enterprises should pay more attention to the problems encountered by new energy vehicles in the rapid development process. Shenzhen Wuzhou When the dragon car is charging, the new energy vehicle's winter mileage is drastically reduced, and the new energy vehicle's winter air conditioner can't be used, we should think about how to improve the safety design of new energy vehicles and improve user satisfaction. This should be the need of enterprises. The "internal power" of cultivation. The real demonstration operation of new energy vehicles in China can be traced back to the “Ten Cities and Thousand Vehicles†project implemented in 2009, extending from the first 13 pilot cities to the present 88 pilot cities. New energy vehicles have achieved significant results over the years, but there are also too many problems. Concerning battery safety, short vehicle cruising range, difficulty in charging, and poor battery thermal management, it has long plagued major auto companies and end users. It should be said that before the implementation of the national and local subsidy policies in 2014, the level of investment and attention of car companies in new energy sources is obviously insufficient. This is why, once the policies are put into operation, batches of new energy vehicles are put offline and put into market operation, What followed was a large number of problems that could not be solved in a short time. It can be imagined that if starting from 2009, major auto companies will vigorously invest in manpower and material resources to explore new energy vehicle technologies, and constantly improve and solve various problems in their own products, then the policy will be invested after the second half of the year. New energy vehicles in the market may be another world. Anyone who knows the R&D and production of automobiles knows that the quality control of automotive products is focused on prevention, focusing on R&D chain management, focusing on IPQP (pre-planning and quality control plan for products), putting vehicles on the market, and then conducting products based on market exposure problems. Improvement is obviously an unwise choice. At the beginning of 2016, all major auto companies are paying close attention to the local subsidy policy, so as to quickly seize the market and expand their operating income. This is the essence of the company's profitability. It is understandable, but a responsible enterprise. Not only need to pay attention to the policy dividend, but also need to pay close attention to the internal, timely organize resources to solve the various product problems that appeared in the early stage, so as to achieve the purpose of improving their "internal strength." This is like a good general. In the early stage of war, not only should we pay attention to and understand the movements of our opponents, but we should also hurry to exercise our own troops, so as to ensure that we can fight and win when we fight. There are several suggestions for companies to cultivate their own "internal strength" from those aspects: 1. The vehicle enterprise should improve the safety design of the whole vehicle. Among the new energy auto parts, the three electric power is the most important. The battery, electric motor and electric control. If the vehicle enterprise wants to start from the safety design of the whole vehicle, it must pay attention to the three electric system. I think that the whole vehicle company in Sanpower has the most right to speak in electronic control. The vehicle company should increase investment and research and development in electronic control, so as to continuously optimize the vehicle control strategy, such as power-off strategy, charge and discharge management, and braking energy recovery. Management, etc., the safety management of the car should still be in the hands of the vehicle manufacturer, not the battery or other suppliers, the car companies can only be in the hands of the electronic control management, in order to be invincible (even if the policy The factors cause the need to replace other types of batteries) and are not kidnapped by a certain type of supplier. 2. Vehicle companies should participate in the design and production of power battery PACK. At present, most of the power battery PACK is designed and produced by the battery company itself, so there are several drawbacks. First, the battery company's strength lies in the battery cell. The battery PACK is similar to mechanical assembly, non-battery enterprise, and therefore PACK. The design quality is difficult to be guaranteed, and the actual supply quality of the battery PACK is also uneven. Secondly, the battery PACK is designed by the battery enterprise to cause the battery to adapt to the overall design of the vehicle, which is obviously not conducive to the vehicle design and quality of the whole vehicle enterprise. Control; In addition, the power battery PACK design needs to fully consider the actual use of the battery, but also take into account the battery's thermal management, sealing, fixing methods, etc., which is obviously not as good as the car company responsible for designing the battery PACK. If the car enterprise participates in or directly takes over the battery PACK design and production, it can not only personally design the PACK shape according to the characteristics of the whole vehicle, but also improve the design quality by means of mechanical design experience. At the same time, it can also cope with the design of the body and battery PACK by taking into account the battery thermal management. adapt. In addition, from the perspective of supply, in 2015, the power battery has been in short supply, largely due to the capacity of the power battery PACK, assembly is the strength of the car enterprise, the car manufacturer responsible for production can improve the current battery to some extent. Status of supply. 3. Improve the cruising range of new energy vehicles. The importance of pure electric vehicle cruising range is self-evident. If the vehicle is loaded with the same battery, how to improve the vehicle's cruising range is an important issue to improve the "internal power" of the enterprise's products, and increase the total load of the battery to improve the cruising range. It is not wise, because it will bring about an increase in the cost of the whole vehicle. As the government subsidies decrease year by year, the increase in the cost of the whole vehicle will continuously compress the profit of the bicycle, which is obviously not desirable. How to improve the cruising range of new energy vehicles and how to reduce fuel consumption in traditional vehicles has the same effect, although the actual measures are slightly different, improve the braking energy recovery rate, reduce the vehicle or battery weight, improve the electric conversion efficiency of the drive motor, use design Means to avoid improper driving habits, etc., are all aspects that can be studied. If we can make breakthroughs in this area, we believe that car companies will be able to differentiate their products and enhance their competitiveness. 4. Overall planning to optimize the thermal management of the entire vehicle. The high temperature in the summer of 2015 caused the battery temperature to exceed the warning value, the vehicle could not be used for anchoring, the low temperature in winter, the battery temperature was too low, the cruising range was reduced, and the air conditioner could not be used. All of these involved new energy vehicles (note that the whole vehicle Thermal management, rather than single-finger power battery) thermal management research. How to arrange the battery in summer is more conducive to heat dissipation, how to protect the battery in winter, how to achieve heat preservation, how to achieve independent heating of the battery under ultra-low temperature, whether the vehicle air conditioner can cool the battery in summer, whether the air conditioner can heat the battery in winter, and the motor work Whether the heat can replace the air conditioner to heat the passenger area, etc., all of which require the wisdom and thinking of the car company, and more need for manpower and material resources. How to do a good job in the thermal management of new energy vehicles is like doing a good job of how to manage the thermal management of various systems (intake and exhaust systems, cooling systems, lubrication systems, etc.) of traditional vehicle engines. Summary: Sayong lost his horse, knowing that he is not blessed. In the blank period of the local subsidy policy in 2016, all major auto companies have entered waiting, and the mentality of confusion, anxiety, and urgency has shrouded in various auto companies. However, if auto companies can seize this blank period, they will intensify their efforts to study. To solve the problems encountered in the 15 years of the new energy vehicle explosion, then after the policy landing, such car companies will seize the opportunity. If a responsible enterprise wants to achieve rapid development on the new energy route, simply relying on the policy dividend can only be a short-lived one, and in the context of the gradual decline of the policy dividend, it will continue to cultivate its own "internal strength" and enhance the enterprise. The overall technical strength and product competitiveness can make the enterprise in an invincible position in the historical flood. SHENZHEN CHONDEKUAI TECHNOLOGY CO.LTD , https://www.szsiheyi.com
