At present, the anxiety of electric vehicle range has always existed. Restricted by the structural characteristics of the battery itself, problems such as the attenuation of winter range and long-distance travel have been plaguing users who buy electric vehicles. This situation has led to more and more users recognizing plug-in hybrid new energy vehicles that can be "oiled and electric", especially consumers who only have one car at home. The new energy solution of "short-distance electricity consumption, long-distance oil consumption" is still the mainstream direction of new energy vehicles.
Special attention should be paid to the large battery + REEV technology route models represented by Leapmotor C10, in a good state of charging environment that is completely consistent with electric vehicles, and the comprehensive vehicle cost advantage is significantly exceeded, and the multi-gear PHEV technology route models with fuel direct drive are clearly exceeded.
However, there are also two technical routes in plug-in hybrid new energy vehicles, one is the series-parallel PHEV new energy architecture with direct drive function, and the other is the REEV new energy architecture that can only be driven in series.
At present, the sales of PHEV models can be said to be far ahead of REEV models, because PHEV models have stronger energy consumption performance and power reacceleration ability than REEV models in high-speed working conditions. However, the new energy intelligence analysis network believes that the REEV drive architecture will become the mainstream of plug-in hybrid new energy vehicles, because with the decline of battery costs, the power battery capacity of REEV models will become larger and larger, just like the Leapmotor C01 and C11 models.
In particular, the REEV model is simpler and less expensive than the PHEV model, so the REEV model and the PHEV model can add the saved car manufacturing cost to the battery capacity under the same situation, and the combination of range extender + large battery will bring users a new plug-in hybrid new energy vehicle experience.
1. Large battery PK small battery, lower cost of the whole life of the car
Since the launch of the REEV model, the most obvious difference compared to the PHEV is the larger capacity of the battery assembly, which also allows the REEV model to have a longer electric range. At present, the electric range of the Leapmotor C01 extended range version of the REEV model has reached 316 kilometers, which is close to the range of an electric vehicle.
Many people buy PHEV models mainly because of the electricity used in urban areas, the low energy consumption of oil for long-distance travel, especially the high-speed energy consumption of multi-gear PHEV is significantly lower than that of REEV models of the same level, because REEV high-speed is also driven by a motor, the higher the speed, the lower the efficiency of the motor, resulting in high energy consumption.
However, the travel of large battery REEV models can allow users to use the extended range electric vehicle as an electric vehicle, especially in the case of no convenient charging conditions at home, the proportion of oil used by PHEV models with small batteries may be as high as about 30%, but the REEV models with large batteries, such as the 300 km Leap C11 extended range version, can allow users to achieve more than 80% of the electricity in the whole life cycle.
As a result, the disadvantage of the REEV over the small amount of oil used at the high speed of the PHEV will no longer be apparent during the life of the vehicle.
2. Large battery PK small battery, more battery life in winter:
This winter, there was extremely cold weather in various places, and the low temperature greatly affected the charging and discharging performance of the power battery.
Therefore, the current mainstream new energy vehicles have excellent power battery thermal management technology, and the power battery is preheated at low temperature. However, the low temperature preheating of the battery and the heating of the air conditioning in the car require the power consumption of the power battery itself, so the electric mileage of new energy vehicles in winter is very unsatisfactory, in the face of the cold climate, even in the weather conditions of about 0 degrees in Hunan, the basic mileage has about 5% attenuation.
At this time, due to the low battery capacity of the PHEV model, the electric range of 100 kilometers may only be able to run 50 kilometers, and after deducting the redundant power of the forced engine start, the electric mileage will be lower, which can not meet the electricity demand for a day, and can only resort to oil.
However, REEV models with large batteries, such as the Leap C01 extended range version, have an electric range of 316 kilometers, and can have a range of 150 kilometers even if they are attenuated, and Leap also has a mandatory pure electric mode, allowing users to use more electricity and less oil as much as possible.
After all, the PHEV model is subject to the direct drive system after the engine starts, and the engine vibration will be more obvious than the REEV model, and the NVH is obviously inferior to the REEV model.
3. Large battery PK small battery, less charging and discharging cycles under the same mileage:
The most worrying thing for new energy vehicle users is the cost of replacing the battery, once the battery is facing attenuation, the cost of replacing it at their own expense is also very large. Although the current manufacturers give users a variety of three-electric rights and interests policies, on the one hand, these policies are only used by the first owner, on the other hand, even if the small battery has the same number of cycles as the large battery, but because the PHEV model electric mileage is shorter, so the same mileage of the small battery charging and discharging cycles must be more.
Some users may interpret the charge-discharge cycle as the number of charges, which is not true. For PHEV models, if the electric range is 100 km, while the REEV model with a large battery, such as the Leap C01, is 316 km, if it runs 300 km electrically. The power battery of the small battery PHEV model has been charged and discharged three times, while the Leapmotor C01 is only once.
So although the total electric range is the same, the number of cycles of a small battery compared to a large battery will be several times that of the REEV model, so the attenuation of the power battery will be more obvious.
The author has something to say:
Previously, the new energy technology of an automobile manufacturer was a multi-gear series-parallel plug-in hybrid technology, and according to the data disclosed by them, it can be seen that the proportion of oil used by users is nearly 30%. When Leapmotor did not release a large battery extended range model, the proportion of electricity consumption has reached 80%. As Li Xiang said, in the future, multi-gear and direct-drive plug-in hybrid systems will give way to REEV models, and the author believes that this is true, especially when the electric range of REEV models reaches 350-400 kilometers, range extenders will become occasional accessories, becoming the best bridge into electric vehicles.
Looking forward to the next three years, the new energy intelligence analysis network believes that hybrid technology with fuel direct drive will mainly focus on low energy consumption and low car purchase cost. The high-performance hybrid vehicle will be based on the REEV architecture, due to the different technical architecture, due to the different technical strategies, and the REEV vehicle will have better and higher reliability because of the simple structure, and better meet the needs of users.
In the past five years, the evaluation team of the new energy information analysis network has been engaged in the evaluation of special wheels and tracks of the REEV technical route. The technical advantage of a longer all-electric range obtained by loading a larger battery can not only reduce the cost of vehicle use, but also obtain more significant tactical advantages.
In the field of civilian vehicles, Leapmotor chooses the REEV technology route based on large batteries, which is highly recognized by military equipment, which not only lowers the cost of using the vehicle, but also highlights the more advantageous reliability advantages brought by the simple architecture.
