Car The energy saving has become a vehicle Electronic Driving force behind the development, with the Oil Increasing the supply shortage and growing environmental pollution, electric vehicles such as electricity-powered vehicles with its energy, Environmental protection The advantages of becoming the focus of the industry. However, even if the electric car has many advantages, but it is a time can not replace the traditional gas-fired power mode, the hybrid vehicle is the new clean electric vehicle with industrialization and marketization of the most promising models. However, Battery , Cost, reliability, longevity, more complex environment, the requirements of high voltage power devices for automotive manufacturers and many other issues facing many problems. Infineon Technologies (China) Co., Ltd. Automotive Business Unit Senior Marketing Engineer Caohong Yu pointed out: At present the main challenges of hybrid cars from two aspects: One is a traditional power systems and electrical systems of coordination; Another is the need for cost control under the conditions of application of automotive electronics in the complex environment of reliability requirements. Caohong Yu: Hybrid cars as a major challenge to traditional power systems and electrical systems of coordination. Fairchild, Senior Manager of the global automotive market, Hans-PeterHoenes believes that a major hybrid vehicle design challenges, is very low cost to create a very complex but highly reliable system. "Electric vehicles can be divided into three categories: hybrid, fuel cell and electric vehicles. Electric vehicles there is a universal problem?? Battery, due to the existence of batteries of various problems in the future to mass production is the most likely hybrid. than hybrid and traditional engine technology increases in three parts, one vehicle control, and second, battery management, third, motor control. "Freescale China Automotive Engineering Manager Kangxiao Dun said. Kangxiao Dun: battery technology is the key to hybrid cars, batteries accounted for the cost of vehicle 1 / 3. Hybrid cars are divided into light (micro) mixed with full hybrid vehicles, the challenges they face are different. Light mixed with the different challenges facing the entire mixed Analysis Cao Hongyu Road, micro hybrid system mixing system and the whole structure in the system is very different, it is more than the percentage of electrical power system, the numerical difference between the total important that quantitative changes in the structure caused by vehicles. Micro-hybrid system to achieve start-stop function normally, the whole hybrid system requires no engine power of vehicles in the case of still life has a certain capacity. Since the coupling is substantially increased, more complex full hybrid system architecture, the design of more challenges. Hans-PeterHoenes analyzes the Road, for mild hybrid vehicles, the chassis (the basic design) is still the traditional automotive design, usually in a normal car on the integration of hybrid characteristics. As the chassis (the basic design) design has been set, the additional needs of all the systems must be able to meet the demand. However, this is not always the best technical solution, so far, the biggest challenge in this regard is the integration of mechanical and electrical integration. In other words, the design requires minimum space requirements. The full use of hybrid cars, the whole design needs to change, not only powertrain, chassis and even had to promote the optimization for mixed. A good design should be designed around the power transmission car, but the traditional program is for designing cars, but the engine placed in the "somewhere." This is a radical change in the concept of design thinking, as determined drive system, or at least greatly influence the shape and appearance of the automobile. "The greatest challenge facing the design is the lack of electric power transmission at high pressure (pressure-driven high-power motors) has extensive experience in the automotive engineer. As with conventional vehicles in different working conditions, so even in the field of industrial drive experienced senior consultants are able to provide assistance is limited. "Hoenes said. Fairchild not only has the power discrete technology, as well as gate driver IC such as IC. This not only applies to low voltage, but also covers the full voltage range up to 1200V. This module integration capabilities will enable customers to optimize fully tested power levels, can solve a number of the parasitic and device interaction design issues.
