With the vigorous promotion of new energy vehicles and the support of relevant national policies, it has also changed many people's consumption concepts. Compared with the range anxiety, after-sales anxiety and road conditions of pure electric models, Qidu personally believes that hybrid vehicles will occupy a very important proportion in the future. In fact, many people have realized now, especially for people who work outside the home, often run long distances, and hybrid vehicles are more suitable than pure electric and fuel vehicles. However, is it better to choose a plug-in hybrid or a petrol-electric mild hybrid? Let's take you to find out.
First, the economic aspect.
1. Car purchase cost: Due to the cost of batteries and other related manufacturing costs, the pricing of plug-in hybrid models of the same level is generally more expensive than that of gasoline-electric mild hybrid models, but plug-in hybrid can enjoy the national purchase tax reduction and exemption policy.
2. The cost of using the car: the plug-in hybrid has a longer driving mileage than the petrol-electric mild hybrid, and the battery pack of the general mild hybrid model is very small, and the pure electric driving mileage is generally a few kilometers, while the plug-in hybrid wants to enjoy the purchase tax reduction policy, the pure electric driving mileage must be greater than 43km. If you mainly use the car for a short distance in daily life, you can use the pure electric mode to drive, which is the same as the pure electric model, and the cost of using the car is naturally low. When the plug-in hybrid model is in a state of power shortage, its working principle is almost the same as that of the mild hybrid, but the brand is different, and the working principle of the mild hybrid will be different.
3. After-sales cost: In terms of maintenance, the gap between plug-in hybrid and mild hybrid is not large, but when the battery pack needs to bear the maintenance cost personally, the maintenance cost of plug-in hybrid will still be greater than that of mild hybrid.
Second, the working principle.
1. Plug-in hybrid.
At present, plug-in hybrid vehicles want to ask which one sells well, except for BYD, there is no brand to compare, although many traditional brands have also launched plug-in hybrid models, but the acceptance of consumers is not high, and for sales, plug-in hybrid models are generally sold as special models.
But no matter which brand of plug-in hybrid, the working principle is not much different, let's just talk about the principle of power starvation. When starting, low speed, and idling, the power battery is used to provide energy; At medium and low speeds, the engine will start, and the engine generally drives the generator to provide energy to the drive motor, and some brands are directly driven by the engine and charged the power battery by the way; At high speeds, the engine generally drives the vehicle directly, and when overtaking or accelerating sharply, the engine and the drive motor provide power to the vehicle at the same time. Due to the different brands, Qidu just said the general working principle, if you don't understand the friends can leave a message to Qidu.
2. Oil-electric mild hybrid.
The gasoline-electric mild hybrid degree is still mainly based on the three Japanese brands (Honda, Toyota, Nissan) to make a brief explanation, and their mild hybrid working principle is still quite different.
Honda mild hybrid: motor drive at start, low speed, idle; At medium speed, it is still driven by the motor, and the engine only drives the generator to provide energy to the drive motor, and then charges the power battery by the way; At high speeds, the engine drives the vehicle directly, and the drive motor generally does not work at this time, and only when accelerating sharply will it provide power to the vehicle at the same time as the engine. To sum up, Honda's mild hybrids are mainly electric-based.
Toyota Dual Engine: Motor drive at start, low speed, and idle; When the speed is greater than 40 yards or the power battery is dead, the engine starts directly and the drive motor provides power to the vehicle at the same time, and its core is the planetary gear. To sum up, Toyota's twin engines are mainly oil-based.
Nissan superhybrid: In all states, the drive motor provides power, and the role of the engine is only to drive the generator to provide energy to the drive motor when the battery is starved, and its principle is almost a range extender. However, the difference with the extended-range vehicle is that its battery pack is small, cannot be charged externally, and cannot enjoy the purchase tax exemption policy.
The above are the three representative brands of petrol-electric hybrid, from their principles, you can choose what you like, and the specific driving experience can go to the 4S store for a test drive, so that the feeling will be more profound.
Third, the policy benefits.
1. Plug-in hybrid vehicles can enjoy the purchase tax reduction policy if they meet the following conditions: pure electric driving of 43km, external charging, and engine displacement 20l。
2. As a new energy model, plug-in hybrid can be on the green card, and in many places you can enjoy unlimited traffic and unlimited license plates, and some places implement free parking for green vehicles for 2 hours.
3. According to the preferential policies of the State Administration of Taxation, new energy vehicles exempted from vehicle and vessel tax refer to pure electric commercial vehiclesPlug-in (including extended-range) hybrid electric vehicles, fuel cell commercial vehicles.
4. Models of gasoline-electric mild hybrid vehicles are treated the same as fuel vehicles and cannot enjoy the above policies.
To sum up, Qidu still recommends everyone to buy plug-in hybrid models, because its use scenario is more suitable for many of our ordinary families.
