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.
In particular, self-owned brand car companies have a clearer idea when planning energy-saving routes, that is, hybrid-based, pure electric supplemented, and traditional.
Hybrid technology is optimistic about the solution
When the domestic and foreign car companies are committed to the research and development of hybrid system technology, the technical routes are also different. From the degree of mixing, there are three technical routes: micro-mixing, medium-mixing and strong-mixing. 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 flow 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.
Main hybrid technology roadmap comparison
From the above comparison, each technical route has certain advantages. However, compared with the practical application of the vehicle enterprise, P2 has obvious comprehensive 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 car-related projects will be in 2017/2018 respectively. Production.
Solar light tower
Solar light tower is efficient and delivers high performance light tower, giving workers good visibility while allowing sites to increase sustainability with zero COâ‚‚ emissions and zero noise, zero operating costs (diesel fuel, maintenance, labor), it is 100% renewable energy, stronger structure can load more power solar panels and batteries, patented rotating mechanism can adjust angle of solar panel to best align with the sun's location to achieve maximum solar yield.
A solar light tower is a portable lighting system that is powered by solar energy. It consists of a tall tower structure with multiple LED lights mounted on top. The tower is equipped with solar panels that capture sunlight and convert it into electricity, which is stored in batteries for later use.
Solar light towers are commonly used in various applications where temporary lighting is needed, such as construction sites, events, emergency response situations, and remote areas without access to electricity. They provide bright and reliable illumination without the need for fuel or grid power, making them environmentally friendly and cost-effective.
These light towers are typically designed to be easily transportable and can be set up quickly. They are also equipped with features like automatic dusk-to-dawn sensors, motion sensors, and remote control operation for convenience and energy efficiency. Overall, solar light towers offer a sustainable and efficient lighting solution for various outdoor applications.
In addition, there are more types of light tower for you to choose from: LED Light Tower, Traditional Light Tower, and Hydraulic Light Tower, Solar Light Tower, etc
