Delphi hybrid system to achieve large-scale production in China

Although Delphi’s news of continuing to sell its non-core assets continues to be reported to the press, the reporter learned from the interview that Delphi not only did not weaken its core business operations, but instead showed a more aggressive and stable style. On June 10th, the reporter interviewed Dr. Kong Hongzhi, Asia Pacific Manager of Advanced Product Development in the Delphi Electronics and Safety Business Unit in Beijing. He learned about Delphi's ideas and recent technical activities from one aspect of hybrid technology.

Hybrid is the preferred transition plan

“What is the true green solution?” Dr. Kong first raised this issue himself during the interview.

“There is no single answer to this question. In the current development stage, Delphi believes that hybrid power is the three major standard technologies—traditional internal combustion engine technology, hybrid and battery electric powertrain system technology, and the latest fuel cell technology. The preferred transition plan."

"Inheritance, parallel transfer" is one of Delphi's important reasons for focusing on hybrid power. After comparing conventional gasoline engines, diesel engines, and biofuels, fuel cells, and hybrids, Dr. Kong believes that hybrid technology can be adapted to various degrees of hybrid and electric vehicles. Both technically and theoretically, hybrid technology is a bridge that connects today and tomorrow.

Dr. Kong said that currently, the main purpose of the application of powertrain technology and its future R&D is to achieve the best balance between meeting local consumer demand, local legal requirements, and cost-effectiveness. As these pressures increase, Demand for hybrid technology is increasing.

"Hybrid technology allows us to achieve electrification, thereby reducing the size of the engine, adding more electronic powertrain systems, which also means that we can reduce fuel consumption and emissions." Dr. Kong believes that Delphi has an advantage in the hybrid field, " Delphi's approach is to provide scalable solutions. We use a modular component approach that includes a set of multipurpose parts that can be exchanged and reused 100%."

“Now we cannot fully realize the electrification immediately. But in order to fully realize vehicle electrification and zero emissions, we first need to use hybrid technology.” Dr. Kong said, “The scalable nature of hybrid technology can make the product gradually closer to the electric The car will eventually replace the engine with a fuel cell or battery pack."

The market needs to go through a transitional phase that requires a certain amount of time and returns to drive this process. Dr. Kong believes that "Hybrid technology has just started in China and will be the medium-term solution for decades to come. It is the right choice for the current market."

Confidence comes from the magnificent goal of the Chinese government

Where does Delphi Hybrid Technology's confidence in China's market come from? In fact, Delphi's confidence comes from the ambitious goal of the Chinese government. By 2011, sales of alternative-energy vehicles accounted for 5% of the total market share. .

In particular, the recent introduction of certain policies and measures by relevant Chinese government departments has made Delphi worthy of expectation: it will implement a subsidy of 600 to 9000 US dollars for each hybrid/electric vehicle; by 2012, there will be at least one hybrid vehicle for each vehicle manufacturer. / Electric vehicles, and the total amount to achieve 5% of the overall sales; special subsidies and support the development of hybrid / electric vehicles and key components.

It is also worth noting that China's power grid facilities are already well-established and are among the most advanced in the world, which is crucial for the realization of vehicle electrification.

Advantage in Mild Hybrid

Delphi has more than 70 years of experience in automotive electronics products. From the design and manufacture of EV1 power equipment, control electronics, energy storage, and hybrid electric booster architectures that participated in various models of General Motors Corporation in the last century, Delphi has obtained more than 100 technologies related to hybrid electric vehicles as of 2000 patent.

At the Shanghai International Auto Show held in April this year, a 750-degree hybrid car from SAIC Roewe attracted attention. The Roewe 750 hybrid vehicle adopts the BSG system (belt-driven starter-generator integrated machine) technology and possesses two prominent features of “Intelligent shutdown and zero emission” and “Environmental protection and dynamic performance”. The maximum speed is 205 kilometers per hour. The mileage is 500 kilometers. As the first self-owned branded hybrid car for industrialization, SAIC Motor is expected to achieve a comprehensive fuel-saving rate of 20% by the end of 2010.

In fact, as the supplier of the SAIC Roewe 750 hybrid vehicle system solution, Delphi currently has more than one Shanghai-based vehicle at home. It is understood that there are many domestic brands of car companies and Delphi in varying degrees of cooperation.

From the series of hybrid technology solutions brought by Dr. Kong, it is not difficult to see that Delphi’s technology includes not only the weak mix, but also the full mix of plug-in hybrid electric vehicles and range-extended electric vehicles. Battery controllers, hybrid and electric vehicle controllers, DC/DC converters, traction inverters, high-voltage battery pack systems, parking-start-up systems, and a variety of different types of hybrid solutions, especially at lighter levels Hybrid aspects.

Has already prepared a suitable mass production system for Chinese customers

To provide customers with high-quality, high-tech, affordable hybrid power systems - from power electronics and energy management systems, to electronic/electrical architectures, heat exchange management technologies, to automotive aftermarket expertise - Delphi has not only The whole set of technology is ready, and after-sales service is also taken into consideration, especially for the price to be affordable to consumers.

"Essentially, all Delphi's hybrid and electric vehicle systems are completed in a standard, modular design that allows us to maximize the reuse of modules to reduce the cost of hybrid vehicles through economies of scale." The doctor said. Obviously, Delphi is definitely not going to be "small" in the Chinese market.

"Because of considerations such as cost and integration complexity (production items), weakly mixed hybrid vehicles will be the first to be launched in the Chinese market, which also takes into account the flexibility of the programs and the relatively low output of domestic manufacturers." In this regard, Dr. Kong specially recommended two low-cost, low-system-competitive power electronics solutions to Chinese manufacturers that will be launched in 2010. One is a micro-mixing system with a 14-volt belt drive. The stop function can achieve 4% to 8% reduction in fuel economy and CO2 emissions. This system, combined with Delphi's engine management system, can significantly reduce emissions, fuel consumption, and noise pollution, and is particularly effective in applications in cities with large traffic volumes such as Shanghai and Beijing. The other is a 120 volt power electronic box weak-mix system that integrates an inverter, a voltage regulator, a hybrid controller, a battery safety unloading unit, and a battery pack. Integrating them into a single module is a weak one. The hybrid drive system can be used in a variety of voltage and power environments and can be upgraded for different applications. The product adopts air cooling technology and can be easily put into the trunk of a passenger car, with a very flexible interior layout scheme. Soon, the product will be put into production at the Delphi plant in Suzhou.

Compared to the hybrid model of a well-known brand that has already been put into mass production, Delphi's 120 volt power electronic box weak mixing system weighs less than half and is 20% smaller, but its power is stronger and its regeneration ability is stronger.

Follow the big trend to develop green products

Following the trend of development is the Delphi style. Dr. Kong said: “The current green environmental protection has become an overall trend. It has a huge impact on the automotive industry. The demand of various mobile platforms for electricity and related traditional energy far exceeds our current production capacity.”

“Ultimately, we can completely replace the engine with fuel cells or battery power. This will be our ultimate goal. But now we need to develop various kinds of long-term or short-term solutions. This is an extremely complex problem.” Dr. Kong stressed "The advantage of hybrid technology is that it can better improve fuel economy and lower fuel consumption without having to replace conventional gasoline or diesel engines, and it is a future-oriented solution that is a process of technology conversion. Preferred transition plan."
