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

Hybrid HEVs and EVs drawn from side to side from time to time on Shenzhen roads remind us that the era of electric vehicles has come and that we are hoping to gradually get out of the rapidly rising nightmare of gasoline prices and into a low A new age of carbon technology.

According to a moderately optimistic estimate from IMS Research, a market research firm, up to 7% of light-duty vehicles will be EVs by 2016, and that share will rise to 15% by 2020. One hybrid will account for two-thirds, the remaining one-third will be plug-in hybrids and pure electric car points.

Mark Munzer, director of automotive electricity drive at Infineon, OPM, said: "The global shortage of oil resources is starting to fuel the demand for electric vehicles. In addition, government support including China, Japan and Israel is also driving the electric vehicle market A key factor in development, the key to the success of the electric car market in the future will largely depend on the price of gasoline and the cost of lithium batteries. "

Another big drag will come from vested interests in the existing automotive supply chain as electric vehicles will bring about rapid change at all levels, including driving habits, supply chains, infrastructure and car services.

Electric vehicle drive mode changes, but also makes the cooperation in the industrial chain diversified. For example, the depot buys parts suppliers for motor systems and even entire drive systems. In battery management and control systems, OEMs generally lack the ability to independently develop batteries and generally rely on battery module suppliers to provide a complete package solution. Slightly research and development strength is the choice and semiconductor suppliers to develop.

Although lithium iron phosphate for electric vehicles in the cost, power density, reliability, service life, there are still many challenges. However, for the long-term Chinese market, pure electric vehicles are the trend of the times. Hybrid HEV or PHEV hybrid technologies can be used as supplementary technologies until the corresponding charging network and corresponding standards are not perfect.

Mark Munzer said electric cars have brought a divisive revolution to industry. This is not only reflected in the cooperation of the automotive industry chain, will also be reflected in the future with the electric car-related business model. In addition to continuing to consolidate its cooperation with tier one suppliers, he believes that automotive semiconductor manufacturers will become truly system partners for electric car makers.

Currently, Infineon, Renesas Electronics, Freescale, STMicroelectronics is a major automotive semiconductor supplier. Infineon in the past two years has been in the automotive semiconductor market leader in the first, and power devices (including automotive power devices) market is ranked first in many years. Mark Munzer claims that compared with its major competitors, Infineon's automotive product line is more comprehensive and covers all areas of low and medium voltage, the advantage is reflected in automotive high-voltage power devices, and in the automotive IGBT module, the current rival Mainly Mitsubishi Electric and Fuji Electric and so on.

Infineon's current offering for the EV market is the HybridPACK family of IGBT modules, including the HybridPACK 1 and HybridPACK 2. Among them, HybridPACK l for such as field hybrid and battery charger 10kW to 30kW applications, HybridPACK 2 for 40kW and 100kW of power for all-electric hybrid and pure; and EVS25, Infineon announced the launch of the Chinese market suitable Light-mix and pure-electric HybridPACK l module with PinFin, power range 30kW to 40kW.

The importance of power semiconductor devices for electric vehicles is clear. It is understood that China's automotive IGBT chips rely on these European and American semiconductor companies, local automotive IGBT / MOSFET reliability and EMC there is a big problem, the current technology is still difficult to achieve breakthrough in commercialization.

The quality and reliability of automotive semiconductor devices are crucial. Mark Munzer believes that meeting the 1ppm semiconductor device failure rate is not enough. He said that if a single automotive semiconductor device failure rate is 1ppm, then the failure of the ECU by multiple components will reach 300ppm, an average of 50 ECU units per vehicle to calculate the failure rate of the car will be As high as 1.5%; therefore, from the security point of view, Infineon goal is 0ppm device failure rate.
