With the official release of part of the interior information of the second new car L9, this full-size new energy SUV that is larger than the ideal ONE size and more expensive has also attracted the attention of many fans and friends.
According to the currently known news, the ideal L9 is still the positioning of the milk daddy car, not only the size is larger, the length of the car reaches the 5.2m level, which is comparable to the Mercedes-Benz GLS BMW X7, and the power system still continues the ideal ONE's extender power form, but it is upgraded to a 1.5T four-cylinder range extender, which can achieve pure electric endurance of 200km, extended range endurance of 1000km, and full power and full fuel cumulative endurance of 1200km.
5.2 meters of full-size SUV equipped with 1.5T, this power specification is absolutely unprecedented, when there is electricity, it is fine, but the battery capacity is limited after all, many people will naturally ask, is there no small horse-drawn cart?
To answer this question, we may wish to find the answer from the ideal ONE that has been listed, and the extender technology it applies.
An ideal for a different path
When it comes to new energy vehicles, people generally know more about pure electric (EV) and plug-in hybrid (PHEV), but if you talk about extended-range electric (EREV), most people will still be confused, and it is also after the ideal car that the extended-range technology has begun to be known by more and more people, and has gradually become popular in the industry, including Lantu, Q&I M5 and the new player Niu-created self-touring NV, all equipped with range-extending technology.
In fact, as a form of energy drive, range extender technology is not the first ideal car, ideal car is not the first brand to introduce range extender technology in the Chinese market, as early as 2018, SAIC-GM launched the VELITE 5 model in China, this new energy vehicle full of science fiction inside and outside shape, is a range extender electric vehicle.
If the ideal car is the key driver of the popularization of extended-range electric technology, then General Motors is definitely the grandfather of range-extending technology, because the technology used in VELITE 5 is basically derived from GM's Chevrolet Vollanda Volt, which was released as early as 2011.
However, VELITE 5 has just begun to determine the final failure of the outcome, on the one hand, consumers for the extended range electric vehicle has no concept, so are more cautious, and SAIC-GM in order to improve the acceptance of the market, choose to velite 5 official definition as plug-in hybrid model to sell, but the ensuing problem is more fatal, this car due to the hasty introduction of technology, three electricity non-domestic, and does not meet the national standards for new energy vehicle subsidies, so not only the cost of the vehicle can not be reduced, It is also impossible to enjoy the policy dividend, in the period when new energy vehicles were seriously subsidized and dependent, there was no policy dividend, in fact, the death penalty of this car has been basically announced.
On the other hand, although the VELITE 5's sci-fi-like appearance is eye-catching, the hard wounds are also too obvious, not only the internal space is narrow, but the central aisle in the rear row has been forcibly pulled up due to technical factors, becoming a thorough 4-seater car, and the practicality is greatly reduced.
The untimely VELITE 5 and extended-range electric technology failed to achieve SAIC-GM, but achieved the ideal car, so why did the ideal do it, and the ending was so different?
The reasons for this naturally include the problem of market rhythm and whether the product form meets the market demand, but in addition to these reasons, the different understanding of the extended range electric technology of the ideal car is also one of the key factors.
The extended range electric power transmission path is very simple, the internal combustion engine does not drive the wheels, only for power generation, and all the work at the driving level is left to the motor to complete.
However, in the process of conduction, there are many articles that can be done, and the ideal car choice is a solution for a light internal combustion engine and a heavy battery motor, and it is also a very rare solution in the application of range extender technology in the past.
Small range extender + large battery motor
The range extender technology used in the ideal car is different from the previous range extender technology, the internal combustion engine weight has been reduced, equipped with a larger capacity battery, and the motor performance is excellent, which is a more inclined because of the BEV concept of the extender technology. Taking the ideal ONE as an example, it uses a 1.2T three-cylinder range extender, but with the front 100kW, the rear 145kW dual-motor four-wheel drive system, the acceleration time of 100 kilometers is only 6.5 seconds, and the battery capacity is 40.5kWh, which is basically equivalent to pure electric vehicles.
The reason for this design, on the one hand, the ideal ONE's internal combustion engine technology level is insufficient, and this is also the advantage of traditional car company technology, the ideal needs to avoid the technical barriers of the internal combustion engine; on the other hand, the unique concept of the ideal car is caused, such as the previous range extender technology model, after the range extender begins to work, there will be problems such as poor NVH, power performance decline, etc., and the ideal car's own range extender technology design will make up for these deficiencies to a certain extent.
The whole vehicle is analogous to a huge pool, then the battery capacity is the pool itself, the motor drives the wheel to consume electricity is to discharge water, and the range extender to generate electricity is to add water. Due to the large electric capacity, the reservoir is very large, the range extender only needs to maintain a certain power of smooth operation, continuous water, you can meet the daily needs, the range extender load will not be particularly large.
Even under a large power request, the release speed is accelerated, there may be a situation where the speed of adding water is not as fast as the speed of the water release, but because the volume of the pool itself is very large, do not worry too much, because no one can always accelerate at full speed, there will always be a uniform driving or downhill section, in this case, the range extender can still maintain relative restraint in the control of the power generation, as long as the back is slowly and smoothly generated, it can still ensure that the water in the reservoir can be slowly replenished.
Greater battery redundancy allows ideal ONE to not have to worry about insufficient power, and the NVH can be maintained at a good level after range extender start-up, which is also the result of ideal's unique understanding of range extender technology.
However, in extreme cases, if the battery power will be completely exhausted under the extremely high power request for a long time, and only rely on the power of the range extender itself to drive the vehicle, then the overall power performance of the ideal ONE will be greatly reduced, and the working state of the range extender itself will become more extreme, not only the noise will increase, and even the failure will occur.
Although this kind of thing is relatively rare, but it is not unheard of, before, there is an ideal ONE car owner in the 5000 meters altitude plateau for a long time to climb the hill, due to the range extender power generation power is affected, the continuous climbing power request is also very large, the owner himself driving is also more intense, resulting in battery power is consumed, the range extender water temperature alarm, and finally overheat the pot.
summary:
Ideal car range extender technology belongs to a more inclined BEV concept of the range extender technology, with the help of large capacity batteries, even if the use of small range extenders with low specifications can still achieve a better level of power, and also has the advantage of better NVH performance, after joining the range extender, successfully solved the problem of pure electric vehicle mileage anxiety, so the ideal L9 in the future will be a small horse-drawn big car has some scruples of the riders can rest assured, the daily use of this 1.5T range extender will even exceed your expectations.
