Recently, the network for Nissan Xuanyi e-power, there is indeed a lot of criticism, if the people are not more this statement does not know whether the big guys will recognize, but Nissan Xuanyi e-power in many key points is very worth exploring.
If the hybrid from Shuangtian is addition, then Xuanyi from Nissan can be said to play subtraction out of the new highland, without adding any additional conditions, but also to "reverse" all the advantages and disadvantages of fuel vehicles.
In the case of low-speed and high-torque driving of fuel vehicles, the energy of high torque redundancy after the engine speed is slowed down by low gears is directly consumed, and the energy can be recovered as the key. Let all the power output of the fuel vehicle serve the mileage as much as possible, hand over the high torque to the redundant energy stored by the battery, and give the high speed to the engine straight out.
Note: The direct out mode of engine + generator + motor requires a wider voltage to reduce energy loss, and at the same time equipped with a wide voltage high-efficiency battery to quickly store energy, the whole electric driving experience will be better.
Most hybrid models of generators and motors are more to take into account the mainstream pure electric model battery characteristics, high speed using the engine multi-piece clutch type straight out of the way, low speed rely on battery energy storage, the efficiency requirements of the generator and motor is not the primary factor, so that the number of engine repeated start times will be more frequent, the driving experience will be poorer.
Enduring the burden of hybridization and pure electricity anxiety for the sake of the green card becomes key. Do not blindly meet the "green card" requirements to increase the capacity of the battery, adhere to the first principle.
As a user in most cases, it is easy to be biased by a variety of data and functions, such as plug-in hybrid in special environments, in addition to the just needs of a special group of people (with private charging piles or high-end online ride-hailing cars), it is more to meet the green card policy of first-tier cities.
For most users, the body weight is larger and the after-sales cost is higher, and the fuel consumption is relative to the depreciation and maintenance cost of the whole vehicle. At this time, some people will struggle with the problem of buying pure electricity, some people will pursue the driving experience brought by pure electricity and there is also a policy green card. It's green again! In fact, in cities with non-limited green licenses, the cost of buying green models is actually not low.
Compared with fuel vehicles, there is less gearbox, there is no loss of power in the transmission process, and greatly reduce the weight and cost of maintenance at the same time, the intervention of fast-charging batteries, the high torque and brakes generating redundant energy at low speeds are stored and released in a timely manner, reducing energy consumption and fuel consumption.
Compared with pure electric models, it has a longer endurance and faster refueling speed of the same 400 km (refueling relative charging) compared to 1 minute to fill the fuel tank with 20 liters of fuel (about 0.5 yuan per kilometer for urban road testing) for a total of 200 yuan |
40 minutes fully charged (fast charging situation 400 km endurance model actual mileage 30% off 280 km calculation, winter will be shorter) Total: 80 - 100 yuan or so, in terms of time nearly 40 times faster, but the price difference is only 2-3 times, do you think it is so cost-effective?
So what are our needs? The road is easily overtaken by Xuanyi, even if you drive a fuel "steel cannon" who cares if you are "evil" or "elegant"?
Compared to the "aunt car" better control driving experience, acceleration easily PK off some 100,000-level fuel version of the "sports coupe". However, the fuel consumption is much lower than that of the "entry-level performance car", which is much more obvious than the current popular "small steel cannon" advantage.
Summary: In fact, Nissan's e-power is easy to mistakenly think that "extender" in fact, Nissan e-power is more like a "straight-out" battery than a "straight-out" battery, which is only a rapid storage and release of excess energy on the basis of a straight-out type. The key to solving the Nissan e-power problem is that its battery is solving the "fast charge and fast release" mode of efficient energy storage and release, which is the opposite of the idea of developing long-endurance batteries, and also perfectly avoids the problem that long-lasting batteries need larger volume and weight. Let's understand the relative "cumbersome" addition mode = what is missing, although the final energy consumption is reduced, but the price behind it is the larger weight of the whole vehicle and the higher cost of car building, but in the end, it is necessary to shuttle through the "policy" or cater to the user In fact, the key to finally calculating a car is the cost of the car.
