How to choose between plug-in mixing and range extension?After reading these characteristics, you will understand
It's 2023, and you're still thinking about fuel vehicles when you buy a carNo, consider a pure electric model?Range anxiety is a bit unbearable, that is, hybrid new energy vehicles. Plug-in hybrid new energy can be on the green card, can solve the range anxiety and take into account consumer spending, at the same time, there are two branches: plug-in hybrid and extended range hybrid, how to choose?
Let's talk about the extended-range hybrid first, and his representative models are the recently popular Huawei Wenjie series and the ideal L series. This is also one of the more popular hybrid modes at present. Take the sales volume in November 2023 as an example, the ideal is 410,000, and the question world has also reached 180,000, all of which have created a new high for their own brands.
There are only two ways to work with extended-range hybrids: pure electric and series, that is, EVs and HEVs. Corresponding to the pure electric and hybrid mode, in which the HEV mode only has a working condition in series, and the engine does not participate in the direct drive of the car throughout the whole process, but is only responsible for generating electricity and driving the motor to drive the vehicle, with a single working condition. This mode solves the problem of fuel economy and smoothness through high-efficiency motors in low-speed road conditions, but in high-speed road conditions, the efficiency of the motor will be discounted, and correspondingly, the power consumption rises rapidly, so that the power generation power of the engine will be greatly improved, in order to maintain the balance of power, and fuel consumption will also be increased synchronously.
The second is plug-in hybrid, which is mainly represented by BYD's super hybrid, which is also used by Geely and Great Wall. According to the sales of new energy vehicles in November 2023, BYD's sales reached a record high of 3020,000 units, including 170,000 EV models and 13 DM models10,000 units, the DM model is a super hybrid. Geely's new energy vehicle sales also exceeded 20,000 units.
How does a plug-in hybrid work?On the basis of the extended-range hybrid, two working modes of parallel connection and direct engine drive have been added. In low-speed road conditions, the working principle and mode of the two hybrid modes are the same, both are electric motor work and engine power generation, motor drive;In medium and high-speed road conditions, the parallel and direct drive modes of plug-in hybrids come into play. In the medium and high speed mode, the engine power generation is always in the optimal working range, and in the process of providing direct drive, there is redundant power generation capacity, which can achieve both drive and power generation, and the fuel efficiency is also higher.
Since plug-in hybrids are more efficient and better, why is there a range extension mode?Due to the limitations of technology accumulation and cost, different car manufacturers will have certain trade-offs on the path to achieve hybridization. At least in terms of design, manufacturing and cost, range extension is a shortcut, at least to solve the key problem of the existence or absence of new energy hybrids.
So the question is, how to choose between these two plug-in hybrids?Because different car manufacturers choose different routes, and at the same time, they also distinguish the car functions, which brings great difficulties to the user's choice, and the selection difficulty occurs. Two suggestions for users who want to buy a hybrid new energy vehicle:
1.If you pay attention to the fuel-saving performance of the vehicle, and there are many comprehensive urban and high-speed scenarios, the plug-in hybrid model will be preferred, which will have more advantages in terms of use experience and car cost. 2.If you focus on intelligent driving and riding experience, most of the use scenarios are in urban conditions, extended-range hybrid and plug-in hybrid can be selected, the representative model of intelligent assisted driving is the M7, and the representative model of the color TV refrigerator sofa is the ideal L series.
