Today, plug-in hybrids and extended-range hybrids are the mainstream of hybrid models in the marketTechnical route。These two hybrid options have sparked widespread controversy. Despite the idealCarsWith the extended-range hybrid, it has been a huge success, but many people still think that plug-in hybrids are betterTechnical route。On this issue, Academician Ouyang of the Chinese Academy of Sciences was at one timeCarsA clear answer was given at the technical forum.
In addition, various automakers are choosing hybridsTechnical routeThere are also differences on . OnlyBYDGeelyCheryChang'anEast windand other traditional domestic brands have plug-in hybrid technology, while most of the new EV manufacturers have adopted extended-range hybrids. So, does this mean that range-extender hybrids are the way to go?
From a technical point of view,Plug-in hybridsThe development of this type requires deep technical strength and a large amount of capital investment. Currently, onlyBYDGeelyCheryChang'anEast windand other traditional independent brands have self-developed plug-in hybrid engines. These engines incorporate many advanced technologies that cannot be used by gasoline vehicles, improving power performance and reducing fuel consumption. It is worth mentioningGeelyCarsAlso specifically for:Plug-in hybridstype launched a custom engine. In contrast, the new EV manufacturers chose the extended-range hybrid technology mainly because of the lack of technology accumulation, and as a result, it was portrayed as an advanced image in the publicity.
In addition,Plug-in hybridsIt has a variety of operating modes, the most important of which is the direct engine drive mode. When driving on highways and in urban areasPlug-in hybridsThe momentum is still strong, and relativelyExtended-range hybrid vehicleFuel consumption is lower. WhileExtended-range hybrid vehicleThe engine cannot be driven directly, and the electric motor can only be driven by fuel power generation. Therefore, in the power loss mode,Extended-range hybrid vehicleThe fuel consumption is higher. Therefore, at high speedsCharging pilesIdeals can often be seen on the topCarsIn the case of charging.
In addition, in the daily commuting of the city,Extended-range hybrid vehicleIt mainly relies on electric mode because of the high fuel consumption when the battery is lost. And likeBYDofPlug-in hybridstype, whether it is pure oil or pure electric mode can be selected, due to the use of single-gear mode,BYDofPlug-in hybridsFuel consumption is very low when the power is lost.
Therefore, compared with range-extended hybrids, plug-in hybrids not only consider the performance of the vehicle, but also satisfyEconomyThe need for sex can be said to be the best choice.
Some may mention that range-extender hybrids have the advantage of having a longer all-electric range. However, the increase in all-electric range is actually intended to compensate for the technical shortcomings of range-extended hybrids. Although this makesExtended-range hybrid vehiclecan be used like an electric car, but it must not be a replacementPlug-in hybridstype of advantages. If range-extender hybrids are only considered more advanced because of this, it would be a misconception that bad money drives out good money. And, likeBYDThe Tang DMP model already has an all-electric range of 215 km.
About that, idealCarsFounder Li Xiang also talked about it in the comment areaBYDBYDInsist on using a small battery plug-in hybrid, and high-speed single-gear direct connection is a better choice. It can be seen that Li Xiang only has reservations about multi-level plug-in hybrids, and is not sure whether it is comparableBYDThe single-speed DMI hybrid system is more fuel-efficient. In fact, beforeCheryCarsThere have been attempts at multi-speed plug-in hybrid systems, but ultimately failed.
Currently, there are a variety of hybrid modelsTechnical routeThe exploration is a good thing. The market will naturally make choices. However, there is somethingBYDI've already tried it, like the previous oneBYDDon DM, which has a multi-gear mode and is equipped with a gearbox. But what is the result?And nowadaysBYDDM-i super hybrid and DMP are not only simple in structure, but also more stable and reliable. Today, more than 3 million vehiclesBYDThe super hybrid proves that plug-in hybrid technology in single-speed mode may be just one of themEconomyPracticalTechnical route
In summary, plug-in hybrid technology has advantages over extended-range hybrids. Plug-in hybridsThe model not only has the leading edge in technology, but also can take into account the performance andEconomyThe dual need for sex. The extended-range hybrid has limitations in some respects, and its all-electric range is only increased to compensate for the technical shortcomings. The current market competition will finally prove the advantages of plug-in hybrids. A variety of hybridsTechnical routeis a good thing, and the market will make choices based on consumer needs and feedback.
