With the acceleration of the process of consumption upgrading, the main economic A-class car and the main luxury and comfortable C-class car have gradually found their own positioning, and the development in the era of electrification is extremely rapid, compared with it, the B-class car in the electrification era has always been difficult to break through the expectations of users, and even many new forces have given up this market. In the limited cost, it is necessary to compare technology and comfort with C-class cars, and energy-saving and a-class cars compared with A-class cars. So, what kind of electrification technology best meets consumer expectations?
In the B-segment car market, the mainstream electrification technologies at this stage are extended-range hybrid and plug-in hybrid, among which the extended-range hybrid technology is simple and lower-cost, and has become the first choice of many brandsPlug-in hybrid technology is more costly, but it is more adaptable to driving scenarios and more energy-efficient. Whether from the perspective of user needs or technical prospects, the latter is undoubtedly the development trend of B-class cars, and whoever takes the lead in providing users with more advanced technology will be the first to seize the market.
Judging from the current B-class car overlord - Accord, the first-class i-MMD technology equipped with the Accord plug-in hybrid has undoubtedly come to the forefront in terms of scene adaptability, energy saving, and power loss, so how does the first-class i-MMD dual-motor hybrid system solve the technical problems?
The Accord plug-in hybrid is equipped with the ***i-MMD dual-motor hybrid system, which has evolved from the e:HEV, and the four iterations make it very adaptable, whether there is power or not, temperature changes, it can make the Accord plug-in hybrid achieve "fast, economical and stable" driving performance.
**The i-MMD dual-motor hybrid system uses 2The hybrid system composed of 0L direct injection Atkinson engine and drive motor, in which the engine adopts multi-stage direct injection technology, and the compression ratio is as high as 139. The thermal efficiency is as high as 41%, compared with the conventional compression ratio of not more than 11, the fuel economy of the Accord plug-in hybrid has been greatly improved, in addition, the electronic control and battery systems have been designed to be lightweight, and the volume has also been greatly reduced, which not only makes the Accord plug-in hybrid have the confidence of 4L fuel consumption per 100 kilometers, but also expands the space in the car and improves the comfort of the ride.
The Accord plug-in hybrid is equipped with a large-capacity battery, which not only allows its pure electric range to reach 106km, but also allows the Accord hybrid to have a full-speed range of pure electric drive, quietness and smoothness performance is better, longer pure electric range travel cost is lower, and the comprehensive range of oil and electricity can even reach 2000km, which greatly reduces the refueling and charging time, and makes travel more convenient.
In addition, the drive motor adopts a multi-ring structure, and the maximum speed is increased to 1450,000 rpm, the maximum torque of the motor reaches 335N·m, coupled with 109kW, 182Nm engine data, the power data of the whole vehicle has been comparable to 20T high-power engine, this data is quite abundant for a B-segment car. In addition, the E-CVT dual-motor gearbox has been redesigned, and the engine and electric motor are equipped with special gears, which greatly improves the reacceleration ability at high speeds, and makes driving pleasure in all speed ranges.
In the boiling winter endurance test, the battery life performance under low temperature conditions makes it difficult for many consumers to accept. How to solve the low temperature battery life, Accord plug-in hybrid gives a solution, this new temperature control system, can maintain the temperature of the battery pack in high temperature and low temperature environments, and also supports intelligent remote control, adjust the battery temperature before departure, or use the mobile phone to set the time, keep the battery pack warm. Smarter and more effective temperature control not only ensures battery performance at high and low temperatures, but also extends battery life.
In addition, the Accord plug-in hybrid is also equipped with ADS adaptive damping system, which works similarly to the magic carpet suspension, using sensors to detect the state of the vehicle, and accurately controlling the vehicle through the damping attenuation force, this system has better comfort performance on bumpy roads, and the comprehensive analysis of the driver's logic and vehicle status can also effectively improve the handling.
From the point of view of technical routes, the extended-range hybrid is obviously difficult to solve the control of fuel consumption in the state of power loss, and the solution of increasing the battery is undoubtedly the idea of "adding more water to the surface and adding more water to the surface". In contrast, the plug-in hybrid represented by the Accord plug-in hybrid can effectively use the respective advantages of the electric motor and the engine, and can also have high economy in the state of power loss, which is undoubtedly the most promising technical route for the future B-class car.
It can be said that in the era of electrification, the Honda Accord still plays the role of a leader, evolving from e:HEV to e:PHEV, what remains unchanged is the insistence on driving control and comfort, and the "fast, economical and stable" driving performance has established the position of the Accord plug-in hybrid in the electrification era. The emergence of Accord plug-in has proved that from the perspective of user needs, there is no brand route that cannot be changed.
