As the first batch of new energy owners who eat crabs, they have been driving pure electric vehicles for nearly 7 years, and they have experienced ups and downs. I will tell you the real situation with my experience. In 2015, I started the first new energy vehicle, from the initial battery life of 150 kilometers to the current battery life of over 500 kilometers and 1,000 kilometers, from plug-in hybrid to pure electric vehicles, from charging for 8 hours to 30 minutes now, which is quite touching.
When it comes to new energy vehicles, BYD and Tesla have always been two new energy vehicle companies that can’t be avoided. What is the gap between BYD Han and Tesla Model3 in terms of the same price model? How to choose? Some car owners said that the gap between the two was immediately reflected when they ran a high-speed trip in winter, and some insiders said that the comparison."Motor, battery, electronic control, assisted driving"In these aspects, the gap between the two is high.
Both of these statements tell the advantages and disadvantages between BYD and Tesla from different angles, but they are all one-sided. What is it like to see a new energy vehicle? You also need toEndurance, charging, power performance, NVH comfort, driving experience, safety, space, functional configuration, and cost performance.And other aspects of comprehensive comparison, combined with their own car environment, so as not to buy new energy vehicles and regret.
First, battery life PK: Which battery is "virtual standard"?
Two models with similar landing price, Tesla model3 is equipped with lithium iron phosphate battery, with a battery capacity of 55kwh and an official NEDC battery life of 468 kilometers. BYD Han EV is equipped with a blade battery with a battery capacity of 76.9kwh and an official NEDC battery life of 605 kilometers.
To tell the truth, it doesn’t matter how many kilometers the official cruising range is. The key depends on what the real cruising range is in the real car environment.
"Winter low temperature+running high speed+heating air conditioning" is the "nemesis" of all pure electric vehicles. The charging and discharging performance is affected by low temperature, and the battery life is obviously reduced. The difference is that the actual battery life is reduced more or less.
In the "photoelectric" car test, the distance from Beijing to Zhangjiakou is 200 kilometers, and the whole journey is high speed, and the temperature is about 2-5℃ below zero. The second gear air conditioner was turned on in the whole process, and the average speed was about 105 km/h. BYD Hanman Electric actually traveled 406 km, which was equivalent to the actual endurance discount rate of about 6.7 fold. The Tesla Model3 actually ran 282 kilometers after being fully charged, which is equivalent to the actual battery life discount rate of about 60%.
If it is not in winter, the daily life is mainly based on urban roads, and the high speed is less. The actual cruising range of BYD Han is over 550 kilometers, which is equivalent to a discount rate of about 87%-95%. The actual cruising range of Tesla Model3 is over 380 kilometers, and the actual cruising range discount rate is about 82%-86%.
The difference between the discount rates of the two models is nearly 10%, and the difference is still obvious. Of course, the discount rates of the two models will be different with different drivers and different car environments. This is only for reference.
The reason why there is such a gap mainly lies in the differences in battery technology and electronic control technology between the two car companies. BYD Han is equipped with a blade battery, which is optimized and upgraded on the basis of lithium iron phosphate battery, and adopts technologies such as high and low temperature control and heat insulation. Its energy density even exceeds that of ternary lithium battery, and its endurance is also significantly improved.
In addition, in battery safety test scenarios such as overcharge and puncture, BYD blade battery is more stable, and ternary lithium battery and lithium iron phosphate battery are also far behind in terms of safety.
Second, the contrast dynamic performance
Compared with the same price model, Tesla Model3 is a single-motor rear-drive model with a motor power of 202kw and a peak torque of 404 N m. BYD Han locates a high-performance four-wheel drive model with a total motor power of 363kw and a comprehensive torque of 680 N m. The gap between them is obvious, but if it is also a single-motor model, Tesla’s power performance is slightly better.
In fact, in terms of power performance, whether it is BYD Han or Tesla model3, whether it is a single motor or a double motor, it completely crushes the same level of fuel vehicles, even comparable to four or five hundred thousand fuel vehicles, for example:
BYD’s dynamic performance: single motor power: 163kw, 222 horsepower, maximum peak torque of 390N·m, 0-100km/h acceleration only takes 5.6 seconds.
Power performance of BMW 525: the engine power is 135kw, 290 horsepower, the maximum peak torque is 184N·m, and it takes 6.6 seconds to accelerate from 0 to 100 km/h.
This is the natural advantage of motor drive. When you step on the switch in full load, climbing, overtaking at high speed and starting, I believe you must be the most beautiful boy in front!
Third, assisted driving
Tesla independently developedAutopilot intelligent assisted driving systemIt can be said that it has always been at the leading level in the field of pure electric vehicles. Although many car companies claim that the level of automatic assisted driving has reached L3 level, the same technology can be used and used differently, which can be felt from actual driving.
Tesla’s automatic assistance is more accurate and has a better driving experience. For example, if you turn on the assisted driving in a slightly curved place, most models will prompt that you need to take over the steering wheel manually, and it is easy to run off the road or even run out of the curb. Tesla can still handle it easily without manual operation.
For another example, when waiting for the traffic lights, Tesla’s active braking is relatively linear, and it is almost impossible to feel the sudden sense of stopping. There is no obvious sense of nodding when sitting in the car. Whether the intelligent assisted driving is good or not is mainly reflected in these details.
Fourth, contrast space, functional configuration, cost performance
1. In terms of space,Tesla model3 is positioned as a medium-sized car, with a body size of 4694mm*1850mm*1443mm and a wheelbase of 2875mm, while BYD Han is positioned as a medium-sized car with a body size of 4980mm*1910mm*1495mm and a wheelbase of 2920 mm. In terms of space, BYD Han’s advantage is very obvious.
2. In terms of functional configuration,Byd Han has obvious advantages in passive safety, including rear row and knee airbags, passive pedestrian protection, traffic signal recognition, 360-degree panoramic image, reversing side warning, steering auxiliary lights, as well as parking, 220V power supply, automatic air purification in the car and other functions. If Tesla has the same configuration, it needs to be added at least 20,000 yuan.
3. In terms of battery warranty policy,BYD has a lifetime warranty for the first car owner, and Tesla, like most car companies, has an 8-year or 160,000-kilometer warranty service.
This difference is still obvious. On the one hand, the battery life of pure electric vehicles will decline with the increase of car use time. How many years the battery can be used at present remains to be verified by time and market.
If you need to replace the battery at your own expense, its cost accounts for almost one-third of the price of a new car. Seeing such a price for replacing electricity, I believe that few car owners are willing to replace it at their own expense. In this case, the implementation of lifetime warranty service has solved the car owners’ concerns about battery life to some extent.
4. In terms of charging,At present, the cruising range of most models with full charge is similar to that of fuel vehicles with a full tank of oil. The problem lies in the slow and difficult charging, which has always been the pain point of pure electric vehicle owners. At this time, the charging time is particularly important.
It takes more than one hour for Tesla model3 and about half an hour for BYD Han to charge to 80% power. Compared with the charging time experience, BYD has obvious advantages.
In short, for the same price model, BYD Han’s main advantages lie in power performance, battery performance, safety, space, functional configuration, cost performance, etc., while Tesla Model3′ s main advantages lie in intelligent assisted driving, brand effect, etc., which may be like what some riders said."There is a difference between BYD and Tesla.".
Motorists often ask me how to choose fuel vehicles, pure electric vehicles, hybrid vehicles, extended programs and other models. Here, I would like to talk about my feelings about using a car. I hope my experience will be helpful for riders to choose a car.
In the face of fuel vehicles and pure electric vehicles, I believe many riders will feel that the advantages of pure electric vehicles are obvious after the test drive, but considering the battery life, they are beginning to struggle. In fact, whether to choose fuel vehicles or new energy vehicles depends on their actual car use.
For example, if you already have a fuel car at home and want to start a second car, it is almost a perfect combination to start a pure electric car at this time, driving a fuel car for a long distance and driving a pure electric car for a short distance.
If there are short-distance and long-distance trips every day, at this stage, it is not recommended to start with pure electric vehicles or the problem of battery life. You can choose hybrid models, which can not only experience the advantages of pure electric vehicles, but also solve the problem of battery life anxiety. On the whole, hybrid models are the ideal models at present.
At present, the hybrid market is mainly led by Toyota, Honda, BYD and other car companies. Among them, the hybrid electric vehicle and the 48V light hybrid vehicle have become less and less popular in recent two years. There is no doubt that they save fuel, but they are still fuel vehicles in essence, and they do not have the qualification of "green card", and their advantages are not as good as plug-in hybrid vehicles.
In the field of plug-in hybrid vehicles, Toyota Corolla Twin Engine, Honda CR-V, BYD Tang, Qin Plus, Han DM and other models are all popular, but it has to be said that BYD has a big advantage in the hybrid field. It is said that Qin Plus DM-i is hard to find a car, and it will take 3 months or even longer to pick it up. Two days ago, BYD newly launched two plug-in hybrid models, Han DM-i and DM-P, with the top price as high as 320,000, and the pre-sale order for 10 hours broke 12,000.
To this end, some riders questioned: BYD Han DMp sells for more than 300,000 yuan. Where does its confidence come from? What’s the charm? Let’s take a look at it.
Let me briefly talk about the differences between BYD Han EV, Han DM-i and Han DMp. Han EV is a pure electric vehicle, while Han DM-i and DMp are plug-in hybrid vehicles. The main difference lies in the performance difference. Han DMp is equipped with dual motors and four-wheel drive vehicles, and the acceleration of 0-100km/h takes only 3.7 seconds.
In terms of price, the pre-sale price of Han DM-i cars with a pure battery life of 121km is 21.68w, that of cars with a pure battery life of 242km is 29.28w, and that of Han DMp high-performance models is 32.28w W. Han EV pure electric vehicles are also priced at 21w to 24w, and the prices of the two models are highly overlapping. Many riders may be puzzled and don’t know how to choose.
In fact, for most of our salaried riders, perhaps Han DM-i is more suitable, first of all, the price is close to the people, the cost performance is high, and secondly, the fuel consumption is lower, while Han DMp is more suitable for people who pursue high performance and relatively affluent economy. Let’s take a concrete look at the advantages and disadvantages of Han DM-i and Han DMp.
1. In terms of power, it is infinitely close to the hybrid mode of pure electric drive.
Han DM-i technology can be said to combine plug-in hybrid, extended-range hybrid and oil-electric hybrid. Simply put, it can run in pure electric mode. When the power is exhausted, the fuel engine works. At this time, the engine directly provides power for the motor, and then the motor drives the vehicle, which is similar to extended-range drive.
For example, in daily driving, especially driving on urban roads, the default is motor drive, just like pure electric vehicles. When encountering steep slopes, rapid acceleration and other scenes, the motor and the engine provide the power source for the vehicle at the same time, which has obvious advantages.
In terms of power, Han DM-i single motor has a maximum power of 145kw and a maximum torque of 316N·m, while Han DMp is a high-performance four-wheel drive with a combined power of 360kw and a combined torque of 675 N m..
The speed of pure electric vehicles can be as high as 10,000 revolutions per minute, while the traditional fuel engines are generally within a few thousand revolutions, and the power performance is second to that of the same class fuel vehicles in the scenes of linear acceleration, starting and rapid acceleration. Similarly, the driving comfort is comparable to that of V6 and V8 naturally aspirated engines.
2. Comprehensive fuel consumption
Both DM-i and DMp models are equipped with Xiaoyun-plug-in turbocharged 1.5Ti high-efficiency engine, and its thermal efficiency reaches 43%. In addition, the direct drive of the engine is rarely used in daily driving, and the overall comprehensive energy consumption performance is very good.
This can be seen from the previous generation BYD Qin Plus DM-i that the fuel consumption per 100 kilometers measured by the public under comprehensive road conditions is about 4.3L, which has certain advantages compared with Toyota Corolla dual-engine and Lingpai Rui hybrid models of the same class.
3. Pure battery life and comprehensive battery life
In the past, many car owners spit out plug-in hybrid models, because the pure electric cruising range is too short. The general models have a pure electric cruising range of 70-80 kilometers, which requires frequent charging, which is equivalent to driving a fuel car, which is very embarrassing. However, the pure electric cruising range of BYD Han DM-i and DMp models has been greatly improved, both of which are equipped with blade batteries. The longest cruising range of DM-i flagship models is 242 kilometers, and the basic version is 121 kilometers.
This kind of pure electric cruising range can basically meet a variety of car scenes for daily use. For most car owners, it takes two or three days to charge once. It can be said that pure electric cruising range has got rid of the criticism of "chicken ribs".
4. Comprehensive cost performance
Judging from the landing price,Both Corolla Shuangqing and BYD Han Dm-i are around 200,000. After comparison, it is found that there is also an obvious gap between them.
In terms of battery life,Corolla dual-engine pure battery life is 55 kilometers, and BYD Han dm-i pure battery life is above 121 kilometers. Needless to say, the advantages are natural.
In terms of space,Caroca’s dual-engine positioning compact models, BYD Han DM-i positioning medium and large cars, compared with the body size and wheelbase, the advantages are clear.
In terms of vehicle warranty,Corolla twin engines and fuel vehicles are the same, with a three-year or 100,000-kilometer warranty service, while BYD Han has a six-year or 150,000-kilometer warranty service. The gap is still obvious. After all, plug-in hybrid vehicles are more complicated, and the more complicated the vehicles will be, the more expensive it will be. At this time, the manufacturer’s warranty policy is particularly important, and BYD has undoubtedly given the owners a "reassurance".
In terms of function configuration, BYD Han DM-i has more functions, especially in passive safety, such as rear airbag, knee airbag, passive pedestrian protection, parallel line assistance, 360-degree panoramic image, reversing side warning, parking in place, 220V power supply and other functions. With the same configuration, the price of Corolla double engine is nearly 20,000 yuan more expensive.
All in all,The advantages of new energy vehicles in terms of power performance, NVH comfort, appearance, interior, space and functional configuration are far superior to those of fuel vehicles of the same class. If charging is convenient, don’t hesitate to start with pure electric vehicles directly, but if you have concerns about battery life, then choose plug-in hybrid vehicles.
