The first time I heard about the two-mode concept of automobiles

I was surprised to hear about the "two-mode" concept of the car for the first time. Because my understanding of the hybrid is so-called "hybrid", similar to a Toyota Prius model. But BYD "Qin" The difference is at the same time with a gasoline engine and a motor, oil and electricity can be independently driven drive, which is called "dual-mode" power.

Recently had the opportunity to close contact with BYD "Qin" This dual-mode oil electric hybrid car, for me, this is a large "smart hardware", not only dual-mode concept and mobile phone have similarities, talk about test drive experience and personal impression:

1. Product Logic

The standard name for a model like BYD's Qin is "plug-in hybrid", which means not only that the battery can reclaim the energy charge of a petrol engine, but also that it can charge directly through the charging interface. Also belongs to the Ministry of the New Energy vehicle, in some areas to buy enjoy government subsidies.

BYD Qin built-in battery for lithium iron phosphate battery, this is a kind of energy density is not very high, but the stability is very good car batteries, can reserve the power is 13kWh, that is 13 degrees of electricity, pure electric mode can run 70 kilometers.

BYD Qin's work logic is such, there are ECO and sport two models, the Power has EV pure electric and HEV hybrid Two output modes, I am more curious is why there is no pure gasoline engine drive mode? Actually also very good understanding, as long as the petrol engine in turn, the motor either in the supplementary kinetic energy, or in the recovery kinetic energy, so there will be no pure oil dynamic mode.

(Mode toggle button)

The combination of EV and HEV is that eco-mode is less than 40KM per hour for pure motor work, higher than this gasoline engine is also starting to work, the motor mode is the oil-electric engine has been working together.

2. What's the performance?

If the car is like a mobile phone also have to run a point, BYD Qin is also a run of the emperor. Here the running point is hundred kilometers acceleration time, Qin's official hundred kilometers acceleration time is 5.9 seconds, this time result is quicker than some sports car.

(two sets of powertrain)

The reason is that the two engines are powered together, "dual-core" power, the petrol engine itself is 1.5T power, the single look is not very prominent, but the total output of oil and electricity can be 217kW power, 479n m torque, you can do a comparison, a 4.8L displacement of the BMW X5 maximum torque for 475n m, Isn't it amazing?

Test drive that days to catch up with the Qingming Festival in Shenzhen, not personally tested hundred kilometers acceleration, before the media run out of 5.4 seconds of results, faster than the official data.

3. Intelligent Automobile

Last year I learned about BYD's progress in automotive electronics, this ability, now all to armed in the "Qin", because the Qin is BYD in the home market the highest price of a model, guided prices for 189,800, the domestic car is not cheap. including equipped with the most in the technical function of the most full of thinking on the remote reversing function, the new software upgrade, you can through the remote control key in the car at the same time in the direction of the wheel, closer to the actual driving experience.

(360° reversing image)

Other High-tech configurations include a 360° panoramic reversing image. And BYD's car cloud service, after the app is installed via mobile phones, you can remotely view the condition of the vehicle and carry out remote unlocking and hot cars. Another function is and Baidu map cooperation, through the PC end of a good navigation route, can be directly pushed to the car.

4, test drive experience

I tried two kinds of scenes to drive the Byd Qin, one is the pure electricity mode, driving about 20 kilometers, the power from 87% to 66%, power consumption only 21%, which is more cautious, speed control in the 50km/s driving around the results, according to this algorithm total driving mileage of more than 70 kilometers. At the same distance, the other testers scored higher in about 30%, and if the air-conditioner would consume about 40%.

Compared with the Baic electric E150ev I had previously driven, BYD's Qinyou was as quiet as it was, with a quick start and no quiet to the point where pedestrians didn't notice you, but there was no dry roar when the gasoline engine accelerated. As the overall configuration of the qin is higher, and is a new development of the model, cabin comfort in the electric car belongs to the level of excellence.

Another scene is the movement mode, oil and electricity mix move, I am driving here is a section of mountain Road, up and down the slope is very steep, the next line, the dashboard will show the electricity recovery flow chart, brake pedal is also very foot, no nod feeling, also will not soft lag. In fact, the most power or in the uphill, approaching 45 ° angle of the uphill, Qin can easily cope with, of course, the main force or petrol engine, the speed will soar to 3000 turn above.

5. The way to save money

In fact, many buyers are considering buying Qin such a hybrid, acceleration and environmental protection are not the most important, save money is sometimes seen very heavy. According to a survey by BYD, more than 90% of urban commuters, from the company and home, do not travel more than 50 kilometers, so in theory, the qin in pure electricity mode can complete a day of commuting, gasoline cost is 0.

Ministry of Industry to give the comprehensive operating conditions hundred kilometers of fuel consumption of 1.6L, this has a corresponding formula, can be simply understood as, first pure electricity ran 70 kilometers, the next 30 kilometers of pure burning gasoline.

In addition to saving money on fuel consumption, another money-saving alternative to the Qin Dynasty is to enjoy the subsidy of new energy vehicles, in Shenzhen, because of support for local enterprises, the corresponding preferential policies can be enjoyed, local plus the country, a total of 70,000 yuan to enjoy the concessions, so the price will be at 130,000 yuan, and ordinary a-class home car almost. But in Beijing, plug-in hybrids do not enjoy local subsidies and are less subsidized.

The third place to save money after after-sale maintenance, BYD Qin is 6 years or 150,000 km warranty.

6. Questions about Batteries

About the battery, there are two most concerned about the problem, one is the safety problem, the second is how to charge the problem. On the safety side, the lithium iron phosphate battery is now the most stable of several automotive batteries, as mentioned earlier. I have the opportunity to look at BYD Auto battery factory, mainly supply E6, K9 and Qin these models.

(Charging interface)

The main raw material of the battery is anode material of lithium iron phosphate and carbon cathode material. The whole shape is rectangular and can be viewed as a magnified tile through a specialized base band and diaphragm wound together. The capacity of each battery is 20Ah, equivalent to 20 10000mAh of mobile power supply. The battery can burn after extreme damage, but it will not explode.

Another is the charge of the problem, BYD's charging interface in the tail of the butt, the first to see the standard charging interface. It can be charged at a high current charge, or it can be recharged by a home 220V power supply, which is equipped with a charging adapter, which is equivalent to a mobile phone charger, but a mobile charger is to charge the AC after Buck, and the car is charged with the highest possible current.

(Trunk and standard charger adapter)

BYD Qin gave me the overall feeling is that the oil and electricity mix is the best way to solve the current obstacles to the implementation of new energy vehicles. Not careful long-distance charge problem, also can save a lot of oil money, economic and environmental protection. It is said that BYD to the future model proposed strategy is 542 direction, that is, hundred kilometers accelerated 5 seconds, 4 zones, hundred kilometers fuel consumption 2L, to achieve such a goal, oil and electric mixing is a more feasible way.

BYD Qin still exists in some cities can not fully enjoy this new energy vehicle subsidies, at the same time, because there are two sets of power system work together, as well as the weight of the battery, the quality of the car is relatively large, reached 1.7 tons, more than the general urban SUV. There is also a point, due to the battery a lot of space, BYD Qin's trunk area relatively poor.
