As can be seen from the above analysis, power hybrid is not a mechanical mixing of the power output of a traditional engine and a traditional electric motor. The power hybrid of modern automobiles must combine advanced engine system technology with advanced electric motor systems. The output power of the two must be mixed, and its indicators are also the most advanced.
To sum up, there are three difficulties in power mixing: first, the engine system is the most advanced; second, the electric motor system is the most advanced; third, the power hybrid mechanism must also be the most advanced.
2. Analysis of the reasons why Japanese hybrid cars are most successful
Japan’s engine system technology has long been a world leader, and its electric motor system is also the best. Another point that professionals often mention is that non-professionals want to understand it, but it is difficult to understand the power mixing device, that is, the “planetary gear” mixing mechanism. If professionals want to develop hybrid car products, they must understand the working principle of the product and the conditions for satisfying its motion theoretical formulas. It cannot just be about the layout of the peripheral dimensions of the product. Here is some basic knowledge introduction to this, so as to better understand the technical reasons for the success of Japanese hybrid cars.
1. Take Toyota’s Prius as an example. The output shaft of the engine is connected to the gear carrier of the planetary gear, the generator (Generator) is connected to the sun gear, and the drive motor (Motor) is connected to the ring gear and output to the half shaft. The connection diagram of the planetary gear mechanism system is as follows (see Figure 1).
Figure 1 Connection diagram of the planetary gear mechanism system
In the picture: Engine refers to the engine, Generator refers to the engine, Motor refers to the electric motor, Piniongear refers to the pinion gear, Sungear refers to the sun gear, Planetarycarrier refers to the planetary carrier, Ringgear refers to the ring gear, and Planetarygear refers to the planetary gear.
2. Everyone is basically mature about the basic principles of engines, engines, and motors, and the working principle of the planetary gear mechanism system is:
①The inside of the entire mechanism looks like a solar system. There is a sun gear in the middle, surrounded by 4 small sun gears, and then a large gear on the outside;
②Each gear is rotating. The middle gear is rotatably connected to the four small sun gears around it. The large gear is also rotatably connected to the four small sun gears.
③The output of the engine and motor (Generator) are coupled through planetary gears. Under normal driving conditions, the motor (Generator) can freely switch between power generation and driving states.
3. Features:
Advantages: There is no clutch and the drive system has only one mode. By adjusting the power and speed of the generator, the engine can run at an economical speed; during starting and reverse gearing, the engine does not need to start, and the vehicle is only driven by the motor; during braking, the driving motor acts as a generator to charge the battery, while providing Braking torque.
Disadvantages: The planetary gear will always be in operation, the rotation speed of the main drive motor (Motor) is proportional to the vehicle speed, and it cannot be decoupled from the output shaft. The transmission efficiency in the entire working range is limited and cannot be adapted to larger vehicles. Under high-speed road conditions, a large number of electric drives with low energy efficiency must be relied on.
3. Analysis of the reasons why power hybrid technology is not suitable for Chinese buses
1. Toyota’s Prius is a sedan that uses planetary gear coupling (hybrid) technology. Because the transmission efficiency within the entire working range is limited, planetary gear coupling (hybrid) technology cannot be adapted to larger vehicles. Chinese buses are large buses with a length greater than 6 meters, which is determined by technical principles;
2. China’s new energy vehicles started with public transportation buses, which were basically hybrid technologies from 2002 to 2013. Series, parallel, and hybrid connections have been tried, but planetary gear coupling (hybrid) technology has never been used. Basically, clutch power coupling technology is used. Since the domestic clutch power coupling technology basically fails to pass the test, the mechanical automatic clutch of hybrid buses of the American Eaton Company has been promoted, but its price is relatively high and it has not become popular. Some domestic companies have made many innovations based on learning from the technology of the American Eaton Company. However, product quality is difficult to compare with Eaton. After more than 10 years of hard work, the quality of domestic mechanical automatic clutches has also improved a lot.
3. To succeed, power hybrid buses must overcome three difficulties at the same time, namely, the engine system, motor system, and power coupling (hybrid) technology must be the most advanced in the world. This is basically impossible for the Chinese automobile industry.
4. China’s annual bus production volume is about 150,000, and its public bus production volume is between 50,000 and 70,000 units. Bus manufacturers basically source their engine systems, motor systems, and power coupling (hybrid) mechanisms from outside. Chinese buses are basically sold domestically, and their prices are the lowest in the world. It is required that the engine system, motor system, and power coupling (hybrid) mechanism used in China’s power hybrid buses must be the most advanced. This is basically impossible.
4. Pure electric buses bring hope to the development of “overtaking in corners” of Chinese automobiles
“Overtaking on a curve” is just a metaphor. Some colleagues explained that “overtaking on a curve” is wrong. Traffic rules clearly stipulate that overtaking is not allowed on curves, but they do not stipulate that “overtaking on curves is prohibited.” The basic way to overtake is through “curves”. How do pure electric buses overtake in corners?
1. It avoids the two difficulties that the engine system must be the most advanced and the power coupling (hybrid) mechanism must be the most advanced;
2. The motor system must be the most advanced, the same in China and abroad. This must be tackled. It used to be three difficulties, but now there is only one difficulty left.
3. The most difficult part of a pure electric bus is the motor system, and a more in-depth analysis is the “power battery”. my country’s power battery technology and products are in the first echelon in the world. The conclusion drawn is that China’s pure electric buses are the most technologically advanced.
5. China’s pure electric buses are technically the most advanced, but can they be used?
The bottleneck in the availability of China’s pure electric buses is also the power battery. The lithium iron phosphate power battery can be charged more than 2,000 times at a time, which means it is basically guaranteed to be used for 8 years. The specific energy of the single unit has reached 140wh/kg, and the specific energy of the system has reached 100wh/kg. This indicator is relatively high in daily public transportation events. , which can basically meet the requirements, but there is still a certain gap in dealing with small-probability events.
While waiting for the progress of China’s power batteries, bus manufacturers have given full play to their subjective initiative, such as carrying out lightweight research to improve the continuous mileage of pure electric buses; through the convenience of charging, reducing the labor intensity of multi-frequency charging for bus companies, etc. , currently mature technologies include online charging technology, dual-gun fast charging technology arranged by dedicated personnel, etc.
The conclusion is: China’s pure electric buses are technically the most advanced and usable.
