The official release time of the ideal second production model, the L9, has actually changed. Originally, it was at this year's Beijing Auto Show, but this year's Beijing Auto Show may be postponed due to the epidemic. So, the official release of the Ideal L9 is scheduled for April 16, 24 days before today.
Anyway, I wish everyone good health and remember to protect yourself when you go out!
Back to the point, today is another Wednesday, and the ideal L9's "weekly spoiler series" continues. The theme of today's ideal L9 spoiler is "full self-development", yes, it can be seen from the three major product points of today's spoilers:
Fully self-developed flagship extended range electric system;
Fully developed flagship chassis control system;
Fully self-developed central domain controller.
Let's take it apart in order and talk about it little by little.
Fully developed flagship extended range electric system
In the first and second spoilers of the ideal L9, we can get the approximate endurance of the ideal L9 from the picture information.
The first phase: the central control screen shows the ideal L9 Under CLTC conditions, the pure electric mileage is 200km, and the fuel cruising range is 1000km.
Phase II: Safe Driving Interactive Screen Shows Ideal L9 Under CLTC conditions, pure electric cruising range is 196km, fuel cruising range is 1000km. (At this time, it has traveled 5km, and the average power consumption is 16.8kWh/100km.) ）
In this issue, the Ideal L9 officially announced its true endurance:
Ideal L9 adopts the power layout of front and rear dual motors and four-wheel drive;
The maximum power of the front drive motor is 130kW, the maximum power of the rear drive motor is 200kW, the total power of the system is 330kW, the maximum torque is 620N·m, and the acceleration time of 0-100km/h is 5.3s;
The ideal L9 has a combined endurance of 1315km under CLTC conditions, and the battery pack with a total capacity of 44.5kWh makes the ideal L9's pure electric endurance of 215km. In other words, the fuel replenishment endurance is 1100km.
With the advantage of extended-range electric vehicles using motors as the driving force, the ideal L9 also surpasses most models of the same size. Let's take a look at the data for models of the same size (acceleration performance in order of high to low):
In addition, ideal also specifically mentions:
The self-developed range extender has a thermal efficiency of 40.5% and the fuel-mode heat engine consumes as little as 5.9L/100km (CLTC conditions).
In order to effectively improve fuel economy, thermal efficiency is always an important indicator, whether it is the engine of fuel models and hybrid models, or the ranger of extended range models.
In the process of engine/ranger operation, the heat energy generated is transmitted and converted through multiple links, of which a large amount of loss will occur. At present, the vast majority of engines/rangers have the highest thermal efficiency between 35-40%, and the highest thermal efficiency of more than 40% is not much.
So, what is the level of thermal efficiency of the new ranger of the ideal L9 replacement? Let's compare a few recognized products.
(Toyota Dynamic Force engine)
The first is to compare it with the Toyota Dynamic Force engine family, such as:
Corolla, Asia Dragon and Lexus ES are equipped with 1.5L, 2.0L and 2.5L displacement engines with a maximum thermal efficiency of 40%.
Twin engine models are equipped with engines of 2.0L and 2.5L displacements with a maximum thermal efficiency of 41%.
(Honda EARTH DREAMS HYBRID engine)
In addition to the Toyota Dynamic Force engine family, the Ideal L9 ranger is on par with the engine thermal efficiency of honda EARTH DREAMS hybrid models, such as:
The 1.5L and 2.0L displacement engines of Lingpairui Hybrid, Accord Hybrid and Odyssey Hybrid have the highest thermal efficiency of 40.5% and 40.6%, respectively.
(Mazda SKYACTIV-X engine)
Of course, among the products currently on the market, the thermal efficiency of the engine is 43%, such as:
Mazda SKYACTIV-X engine has a maximum thermal efficiency of 43%;
The BYD DM-i hybrid system is equipped with a Xiaoyun 1.5L plug-in hybrid special engine with a maximum thermal efficiency of 43.04%.
(BYD Snap Cloud 1.5L plug-in hybrid special engine)
Compared with the ideal ONE's ranger, the thermal efficiency of the new ranger of the ideal L9 has been significantly improved, and it has exceeded 40%. However, compared with the current Lantu FREE, which is also a range extender model on the market, there is still a certain gap, and its ranger thermal efficiency has reached 41.07%.
As for the research and development and production of the range device, one thing that can be determined is the joint venture "Ideal Xinchen" established by Laifa Ideal Automobile and Xinchen Power in Mianyang.
The biggest benefit of setting up a joint venture company for the ideal is that the whole process of procurement and product quality can be supervised, and better product control can be obtained.
Fully developed flagship chassis control system
The ideal L9's front "5-in-1" powertrain includes drive motors, rangers, dual motor controllers and reducers, while the rear "3-in-1" powertrain includes rear drive motors, motor controllers and reducers.
The drive motor of the Ideal L9 is a product from the joint venture company "Huixiang" between Ideal and Huichuan. As we can see from the pictures, the integrated powertrain layout before and after the ideal L9 is quite compact. That's why the ideal L9 was able to integrate an air suspension with a CDC electromagnetic damping system into the chassis.
In general, the air suspension has better pressure bearing than the spring suspension, and the CDC electromagnetic shock absorption system adjusts the capacity of the air in the suspension in real time according to the road conditions, which can strengthen the control of body roll, pitch and horizontal runout under different road conditions, and improve the stability of the vehicle at high speed and cornering.
At the same time, the air suspension of the Ideal L9 automatically reduces the body at high speeds to save energy consumption and provides more convenient access to and from the car when parking, loading and unloading luggage. For a larger, full-size SUV like the Ideal L9, it's still necessary.
However, the models equipped with air suspension on the market are slightly different in experience, and as for the driving performance of the ideal L9, it depends on the subsequent experience.
Fully self-developed central domain controller
In spoilers for Ideal L9 it is mentioned:
The fully self-developed central domain controller will use NXP's latest S32G vehicle specification-level chip, and the ideal car will complete the research and development of all hardware, systems and software, and realize full self-research on the functions of the extended range electric system, air conditioning system, chassis system and seat control system, etc., to better ensure the scope and timeliness of the future OTA of the ideal L9.
From this information, you can see that the ideal L9's central domain controller integrates a VCU, a central gateway, and a part BCM, as well as part BMS.
At present, NXP's S32G automotive grade chip has two series: S32G2 series and S32G3 series, of which the S32G2 series processor has been put into production in April 2021, and the S32G3 series is still in the sample stage, and mass production is planned for the first quarter of 2023.
The S32G2 automotive grade chip is equipped with 4 ArmCortex-A53 cores with Arm Neon technology and up to 3 Arm Cortex-M7 full lock-step cores;
The S32G3 automotive grade chip features eight ArmCortex-A53 cores with Arm Neon technology and up to four Arm Cortex-M7 dual-core lockstep (DCLS) complexes.
The S32G2 supports 8MB of system-on-chip SRAM, while the S32G3 supports 20MB of system-on-chip SRAM, improving the integration of real-time core multi-domain fusion. The S32G3 can provide up to 2.5 times the computing power of the S32G2, while also improving the network bandwidth, thus supporting the "software-defined car" feature.
The advantages of self-developed central domain controllers are mainly reflected in two aspects:
On the one hand, the computing performance has been significantly improved, meeting the needs of the new electrical and electronic architecture, while providing more scalability;
On the other hand is the possibility of future OTA upgrades. Because of the opening of related functional sections, the ideal car can better do OTA upgrades. No longer need to rely on different sectors of suppliers to do OTA upgrades, ideal cars can complete the closed-loop upgrade themselves.
At last
This is already the third episode of the Ideal L9 spoiler, and next Wednesday, The Ideal will bring a new spoiler. Now the information I pay the most attention to is nothing more than the information of the intelligent driving computing platform.
So far, we have learned that the information about the ideal L9 covers:
Official release time, exterior interior design, new paint color, new wheel shape, part of the cockpit configuration, part of the auxiliary driving configuration, new interaction mode, power system configuration, chassis system configuration, electronic and electrical architecture...
And the price range: 450,000-500,000 yuan (depending on the configuration).
According to the "routine" of the ideal ONE, will the ideal only launch one model? That ideal L9 according to the configuration of different generation of 50,000 yuan difference, this so-called "configuration" will be what?
Do you want to guess together?
