Automotive electronics: complex daily necessities
Under the trend of increasingly stringent restrictions on gasoline fuel emissions in various countries in the world, which vehicle engine technology meets the requirements of laws and regulations, and at the same time, it can maximize the satisfaction of mobile needs?
The above issue is currently under discussion in the automotive industry. Conservatives believe that traditional internal combustion engines still have a lot of room to improve efficiency and significantly reduce exhaust emissions. Others support the revolutionary "zero emissions", which is Vehicles with electronic engines.
At a Euroforum seminar held in Munich, Germany, to discuss automotive electronics, the two camps expressed their opinions on what might happen in the next five years.
Internal combustion engine vs electronic engine
For those first-tier automotive component suppliers who have to meet the needs of real car manufacturers, they must take conservative and positive actions at the same time; for these manufacturers, although their business is still to design and sell automotive electronic systems to existing The market for internal-combustion engine vehicles is large, and it must be kept in mind that there are no missing business opportunities in the future.
However, the size of the traditional vehicle market now seems to be much larger than that of the electric vehicle market; "The cost-effectiveness of investing a sum of money in the upgrading of internal combustion engine technology is much better than the development of hybrid or all-electric vehicle concepts. "Herbert Demel, chief operating officer of the vehicle and drive system business of Magna InternaTIonal, a supplier of first-tier automotive components, said.
In any case, energy efficiency still plays a major role in technological innovation; by successively "electronicizing" auxiliary devices, the overall energy efficiency of vehicles can be significantly improved. Some experts estimate that the improvement will be between 20% and 30%. between.
In the discussion on "Internal Combustion Engine vs. Electronic Engine" at this seminar, representatives from the German automotive industry were obviously more conservative in attitude than their peers from the Far East; although German car manufacturers have proposed the best possible The blueprint for the development of electric vehicles, some Japanese car manufacturers have already taken the lead in mass production of electric vehicles to the mass market.
Nissan InternaTIonal's business development manager Florian Wunsch said: "Electric vehicles are affordable and can be produced;" The Japanese automaker has scheduled to launch a mid-range electric vehicle in the global market in 2012.
Restrictions on battery technology
Since expensive lithium-ion batteries still represent high value, the industry is also discussing the cost of hiding batteries from consumers, and thus accelerating the market penetration of electric vehicles; for example, Nissan ’s Wunsch believes that vehicle batteries are not necessarily only Along with selling electric cars, you can also rent them to car owners, so that car dealers can exclude the cost of batteries from the price of the car, and avoid the high price of electric cars to deter consumers.
This way of battery leasing can also avoid the inevitable battery deterioration that causes consumers to have a negative perception; according to Nissan's concept, electric vehicle batteries can be recycled after they have deteriorated to the point of being used by general public vehicles, and another "second spring" is sought. : "After the end of the first period of life, these batteries can also be used in vehicles such as stacker trucks, or in the smart grid to play a stable function." Wunsch said.
For many years, energy storage has remained the most critical element of electric / hybrid vehicle design; the discussion on this topic in the seminar focused on how to manage and use batteries. In addition, the emerging business model in the automotive industry value chain has also received considerable attention from participants.
Some people think that the role of "hardware" in the automotive industry, including engines, electronic components, and batteries, will become less and less important; and related emerging businesses such as services and leasing will stand out. "In the automotive industry value chain, we will see similar business models appearing in the mobile communications field," said Demel of Magna InternaTIonal.
Wunsch also agrees with the above view: "The impact of electric vehicles on the overall automotive industry will be similar to the impact of mobile phones on the telecommunications industry." He predicts that such a trend will make the hardware of vehicles become daily necessities, and manufacturers must pass some personalized Function can achieve the goal of differentiation; for example, BMW's Mini series models can be said to be the pioneers to cater to this trend.
In any case, the battery for electric vehicles / hybrid vehicles is still in a special position. In addition to its high price, the price of such parts will not be reduced as fast as other parts or systems. "There is no Moore's Law (Moore's Law) in the field of battery technology;" Wunsch pointed out: "The battery will not follow the same path as the computer CPU."
On another, more technical level, Bosch manager Rainer Kallenbach also agreed that electrification is the future of the automotive industry; he believes that the trend of hybrid and electric vehicles will revolutionize automotive circuit design; he also predicts that the next ten years will It is the golden age of power electronic components. However, additional DC / DC converters, additional energy storage systems (such as super capacitors), and rechargeable batteries will also increase the complexity of automotive power systems.
