When it comes to new energy, many people's first reaction will be pure electric. However, from the user's point of view, pure electric vehicles are not fully mature at present, and "miserable" pure electric vehicle owners on the May Day travel highway abound.
In this case, PHEV, especially long-endurance PHEV, has become the current new energy optimal solution.
So if PHEV is so good, why hasn't it spread among all car brands?
Quite simply, because the technical threshold is too high.
PHEV involves the control and coupling of both the engine power system and the new energy three-electric system, and the complexity of the system is much higher than that of pure electric and extended range electric.
This is also the biggest reason why many new forces use pure electric routes or range extensions when choosing the form of power.
"Wanting horses to run and horses not to eat grass" sounds like a thing that goes against the laws of nature, so for a long time, the previous generation of PHEV technology has not been able to achieve balanced development of three factors: power, economy and cost. And if at this time, you turn your attention to Chinese brands, you will find that the DHT-PHEV adopted by Weipai completely solves all these "stubborn diseases".
On technology Mocha DHT-PHEV "World War I Fame"
Some time ago, mocha DHT-PHEV was listed, playing the slogan of "full scene 0 anxiety", in my opinion, the essence of this sentence is mainly due to its 39.67kWh battery, WLTC pure electric endurance can reach 204km; and even if it is a very hot ideal ONE on the market, WLTC pure electric mileage is only 155km, on the pure electric mileage, Mocha DHT-PHEV is enough to "become famous in one war".
Of course, the simple pure electric mileage is only the epitome of the strong technical strength of mocha DHT-PHEV, in fact, in the combination of driving motor + generator + two-speed DHT transmission, the vehicle engine and motor power output can be seamlessly transitioned between series and parallel, can play the most efficient comprehensive power output, so that performance and low fuel consumption are both, is the mocha DHT-PHEV "full scene 0 anxiety" the strongest underpinning.
As we all know, the PHEV on the market at present mainly has three types of series configuration, parallel configuration, and series parallel configuration, which are arranged in order from simple to complex, from easy to difficult.
For example, the ideal ONE is a typical series configuration, its extender drive mode has been criticized at the beginning of its advent, the reason is because of the backwardness of technology, under normal circumstances, the power of the ideal ONE is only derived from the motor, the engine is only started in the case of insufficient power, simply put, it is equipped with a "fuel charging treasure" for the vehicle, and the lack of high-speed power, high power loss and fuel consumption Natural hard injuries cannot be avoided.
Parallel configuration is the "previous generation" PHEV technology route, represented by German car companies, the simple understanding is to add a set of electric drive system to the internal combustion engine vehicle, compared to the series, its comprehensive energy consumption is lower, and the development difficulty is low, so that many brands have stepped into the door of PHEV. The disadvantage is that it is impossible to drive for long distances with pure electric power, and the fuel consumption naturally goes up again after the engine is exhausted.
The series parallel configuration is an upgrade of the parallel configuration, which can be divided into single-gear series parallel architecture and multi-file series parallel configuration according to the gearbox gear. At present, many joint venture brands use a single-gear series parallel configuration, the advantage is more fuel-efficient than the series, but the disadvantage is that the engine has only one gear, the engine cannot intervene at low speed, and the rapid acceleration cannot be switched to low speed gear, so it is not as good as the DHT two-speed gearbox in terms of fuel economy and power.
The Mocha DHT-PHEV adopts the highest gold content of all the current technical routes, the two-gear series parallel configuration, its engine can directly drive the vehicle, and is in the lower efficiency of the electric motor, the engine efficiency is higher.
The technical difficulty lies not only in the configuration, but also in the FACT-PHEV system to make a very detailed hybrid scheme based on the characteristic curves of the engine and the motor, so that it can accurately control the working mode of the motor and the engine. At the same time, the Mocha DHT-PHEV also designs two gears with different gear ratios of partial power and partial economy in the speed range driven by the engine separately, and adjusts the output torque of the engine through the gearbox.
These "black technology" technologies are reflected in the data that the fuel consumption of the 100-kilometer feeder fuel of the two-wheel drive version and the four-wheel drive version of the WLTC is as low as 5.55L and 6.3L respectively. The two-wheel drive version has a comprehensive endurance of more than 1,000 km, and the four-wheel drive version has an acceleration of only 4.8 S from 000 km/h, which is really wonderful.
On intelligence, the new forces must also be sidelined
In fact, for many of the more expert "technical control", with this SET OFHT-PHEV system, the new car selling for 295,000 is not expensive, but perhaps considering the sensitivity of more consumers who do not understand the technical level to the price of the car, and the role model of Wei Pai as "China's luxury SUV leader", the manufacturer has added a lot of "code" to the mocha DHT-PHEV.
The arrival of mocha DHT-PHEV has made "intelligent" no longer a "special term" for new forces, with its standard NOH intelligent pilot assistance system as an example, which deeply integrates the car navigation system, high-precision map and HWA high-speed driving assistance.
With the blessing of high computing power chips, Mocha DHT-PHEV can support more complex car use scenarios and algorithms, in the actual use process, it can assist drivers to safely avoid, lane changing overtaking, intelligent control of speed and distance in front of the car, intelligent leadership of up and down ramps, lane change protection, avoidance of sink entrance, switching high / expressway and intelligent avoidance of large vehicles and other functions, to achieve a true sense of intelligent pilot assisted driving.
So on the whole, you will find that the Mocha DHT-PHEV is almost a product without defects, in the face of high oil prices, it can achieve pure electric travel like electric vehicles; in the face of the mileage anxiety of electric vehicles, the comprehensive mileage of 1000km makes the user's travel radius become larger; it also walks in the forefront of the same level of intelligent and luxurious experience.
I still remember at the launch conference of Mocha DHT-PHEV, Weipai CEO Li Ruifeng said a sentence: "We are just going to do what new forces can't do, do what traditional luxury brands don't dare to do!" From the current mocha DHT-PHEV to show us the product force, Wei brand this time is to do it, then continue to go on, into the new forces and BBA "hinterland", presumably also just around the corner.
