Why is the power hybrid system not suitable for Chinese buses?
What does it take for electric hybrid buses to be successful?
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.
To be successful, power hybrid buses must overcome three difficulties at the same time. That is, 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.
China”s annual bus production volume is around 150,000, and its bus production volume is between 50,000 and 70,000. 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.
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.
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.
