The key to the success of electric vehicles is the future price of gasoline and lithium battery packs

The key to the success of electric vehicles is the price of gasoline and lithium batteries in the future. Hybrid electric vehicles (HEV) and electric vehicles passing by on the streets of Shenzhen remind us that the era of electric vehicles has come, and we are expected to get rid of the nightmare of rapid gasoline price increases and enter low-carbon technology. New era. According to market research company IMSResearch, by 2016, as many as 7% of light vehicles will be electric vehicles, and by 2020, this proportion will rise to 15%. Hybrid vehicles will account for two-thirds of the total, and the rest will be divided between plug-in hybrid vehicles and pure electric vehicles. Mark Munze, director of automotive electronics and electrical processing lines, Infineon’s latest technology, Infineon’s automotive electrical parts OPM director Mark Munze said: The current situation of the world's oil resources and the beginning of insufficient supply is affecting the market's demand for electric vehicles. The Israeli government’s support and a key factor in promoting the electric vehicle market. The key to the future success of the electric vehicle market will largely depend on the price of gasoline and the cost of lithium batteries. Another major obstacle will come from the vested interests of the existing automotive supply chain, because electric vehicles will bring rapid changes at all levels, including driving habits, supply chain, infrastructure and car services. Changes in the driving mode of electric vehicles have also diversified cooperation in the industry chain. For example, automobile manufacturers purchase from component suppliers for motor systems and even the entire drive system; in terms of battery management and control systems, most automobile manufacturers lack independent development capabilities and generally rely on battery module suppliers to provide overall methods, while those with weaker Ru0026D capabilities Manufacturers choose to cooperate with semiconductor suppliers for development. Although lithium iron phosphate batteries for electric vehicles still face many challenges in terms of cost, power density, reliability and service life. However, as far as my country's remote market is concerned, pure electric vehicles are inevitable. Under the circumstances that the corresponding charging network and corresponding specifications are not perfect, hybrid power methods such as HEV or PHEV can be used as a compensation technique. Mark Munzer believes that electric vehicles have brought a disruptive revolution to industry. This is not only reflected in the coordination of the automotive industry chain, but also in the future operation model related to electric vehicle affairs. In addition, in addition to continuing stable cooperation with Tier 1 component suppliers, he believes that automotive semiconductor manufacturers will become true system partners for electric vehicle manufacturers. At present, Infineon, Renesas Electronics, Freescale, and STMicroelectronics are leading domestic automotive semiconductor suppliers. Infineon has leapt to the top in the automotive semiconductor equipment market in the past two years, and has been ranked first in the power equipment (including automotive power equipment) market for many years. Mark Munzer believes that, compared with important competitors, Infineon's automotive product line is more comprehensive, covering all areas of low and medium voltage, and its advantages are reflected in the high-voltage power equipment of the car. In terms of vehicle IGBT modules, the most important competitors at the time were Mitsubishi Electric and Fuji Electric. At present, an important product launched by Infineon for the electric vehicle market is the HybridPACK series of IGBT modules, including HybridPACKl and HybridPACK2. At the same time, hybridpackl is suitable for users from 10kW to 30kW, such as on-site hybrids and battery chargers; while hybridpack2 is suitable for full-hybrid users with powers of 40kW and 100kW. On EVS25, Infineon announced that it has launched a suitable hybrid pure electric hybrid PinFin hybrid dpackl module for Chinese shopping malls, with a power range of 30kW to 40kW. The importance of power semiconductor equipment for electric vehicles is obvious. It is known that my country's automotive IGBT chips rely on these European, American and Japanese semiconductor companies, and the reliability and EMC issues of local automotive IGBT/MOSFETs, the current technology is still difficult to achieve commercialization. The quality and reliability of automotive semiconductor equipment are critical. According to Mark Munzer, it is not enough to be satisfied with the 1ppm power loss of semiconductor devices. He pointed out that if the power loss of a single automotive semiconductor device is 1ppm, the power loss of an ECU completed by multiple devices will reach 300ppm. Based on an average of 50 ECU units per vehicle, the failure rate of a vehicle will be as high as 1.5%. Therefore, from a safety point of view, Infineon’s policy is to lose power to the device at 0 ppm. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
