Hybrid power technology is the transition of automobile electrification and has great advantages in various indexes.
Many automobile companies are also quite mature in this technical field, among which Honda and BYD are the most prominent typical representatives.
At present, the two most mainstream hybrid systems are oil-electric hybrid system and plug-in hybrid system. The biggest difference between the two is the degree of exercise assistance. So, which is stronger?
-Honda
In order to break through the technical limitations of Toyota, Honda began to develop hybrid engine technology from a very young age, and finally launched its own i-MMD hybrid system.
What is the best hybrid technology? Neither BYD nor Honda agreed. Let's see who does it better.
The hybrid power system is mainly composed of Atkinson cycle engine, E-CVT, intelligent power unit IPU and power control unit PCU.
Take the hybrid version of Honda Accord as an example. The maximum power and torque of its powertrain are 107kW and 175 Nm.
Compared with the ordinary gasoline version, the fuel consumption is very competitive and the power output is better.
The official 0- 100 acceleration result is about 8 seconds, which is faster than a 2.4L ordinary fuel tanker.
Because the hybrid electric vehicle pays more attention to the assistance of the motor, the power gain is not large enough, which also makes the disadvantages of the system more obvious.
The torque of175 N m is too small for medium-sized cars to bring good power output in the initial stage.
In addition to the i-MMD system, Honda also designed different systems for vehicles in different positions.
Including the economical i-DCD hybrid system mainly mounted on some small cars.
The i-MMD system just mentioned is mainly used for medium and large cars.
In addition to the above two sets of hybrid systems, Honda has also equipped its high-end models with a more powerful SH-AWD system, which is mainly installed on some large cars or sports cars. The representative model is Acura NSX.
Usually Honda's hybrid system is mainly based on electricity, supplemented by oil.
Therefore, the main advantage focuses on fuel consumption performance, but the disadvantage of low-speed torque is more obvious.
Representative work of plug-in hybrid power-BYD
When it comes to plug-in hybrid vehicles, BYD must be mentioned.
As the main promoter of plug-in hybrid electric vehicles in China, BYD launched the first generation of dual-mode technology F3DM as early as 2009. Subsequently, the second generation of products was introduced through technical iteration. So far, BYD has launched the third generation dual-mode technology, called DM3.
This new hybrid system has reached a very high level in economy and performance.
The third generation DM3 hybrid technology is mainly optimized from three aspects: engine, motor and hybrid gearbox, so as to further improve the performance of vehicles.
Compared with Honda, BYD attaches great importance to the auxiliary role of motor in power plant.
At present, the maximum power of BYD single motor is 180kW, and the maximum torque is 380N·m, which is in sharp contrast with Honda's too small torque.
In addition to strong performance, BYD also has a good performance in fuel consumption.
For example, BYD's new Qin Pro DM also has excellent acceleration performance, and the fuel consumption per 100 kilometers is as low as 4.3 liters.
It can be said that BYD has achieved a good balance between fuel consumption and performance.
Conclusion: The above is a simple comparison between Honda and BYD hybrid systems. As far as technology is concerned, BYD's plug-in hybrid car is more dominant, but because it needs external power supply, it has stricter requirements for environmental protection. On the other hand, although the performance of Honda's hybrid electric vehicle has declined, it has gained convenience in using the car. Both have their own advantages and disadvantages, and you can choose according to your own preferences.
