How much do you know about the hybrid technology route P2?

In 2020, the fuel consumption limit policy is hanging. At present, major OEMs have done their best to achieve the standard, and have separately developed a technical roadmap suitable for them. Hybrid is one of the effective ways because of its energy saving effect. Obviously, it can better meet the needs of the current market and consumers, and is highly valued and optimistic by car companies.

Especially for self-owned brand car companies, the ideas are more clear when planning energy-saving routes, that is, mixed-mix, pure electric supplement, and tradition.

Hybrid technology is optimistic about the solution

When domestic and foreign auto companies are committed to the research and development of hybrid system technology, the technical routes are also different. From the degree of hybridization, there are three technical routes: micro-mix, medium-mix and strong-mix. Relatively speaking, among the three routes, micro-mixed investment Smaller, strong mixed fuel economy effect is obvious and there is a certain subsidy, the domestic advantage is more obvious. The medium-mixed structure is relatively compact and complex, and the investment is relatively large. Japanese vehicles use this technology.

Corresponding to micro-mixing, medium-mixing and strong mixing, there are three main technical solutions that are currently focused on the market: 48 volts, ECVT, and P2.

48 volts: The micro-mixing technology was mentioned earlier, but the policy has been on the sidelines. After the announcement of the 2020 fuel limit standard, major component manufacturers finally saw the opportunity and announced domestic plans. The technology investment is small, but the fuel saving effect is not as good as ECVT and P2.

ECVT: This technology is relatively special. It uses a special planetary gear structure. At present, the ECVT can be divided into input split type, output combine type and conforming flow type. The representatives are Toyota Prius and General Voltec. And the General AHS (Advanced Hybrid System). The product has a remarkable fuel-saving effect and a compact structure, but the development cycle is long, the investment is large, and the price is relatively high.

P2: In Europe, P2 hybrid technology solutions are more popular. This technology has less investment, just adding a motor and a split clutch between the engine and the transmission. The engine and gearbox can achieve mixing without major changes. Mainly used for plug-in hybrid and strong mixing.

Comparison of main hybrid technology roadmaps

From the above comparison, each technical route has certain advantages. However, compared with the actual application of the vehicle, P2 has obvious advantages in terms of investment cost, fuel saving effect and subsidy, and is gradually adopted and applied by the OEM. BorgWarner, who has a technological lead in this respect, revealed that the first batch of core component modules matching the P2 hybrid project will be made in China in 2016, and other supporting projects with car companies will be in 2017/2018 respectively. Production.
