talks about new energy vehicles. There are many types of models, including plug-in hybrid, pure electric and extended-range hybrid models. The first two are mostly the first two. The extended-range technology is "hot" by Ideal Auto , but it has also been criticized by many people. As for whether it is easy to use or not, I won't comment.
Ideal Auto started using range-extended technology since its first car Ideal ONE 2. Now the second model L9 still uses range-extended technology, which has improved technology compared to Ideal ONE. For Ideal L9, how does the extended-range technology perform?
has different appearance designs and
First from the appearance of L9, the front of the Ideal ONE has a huge air intake grille, which is very close to the traditional fuel vehicle design. Ideal L9 is a brand new family design language, with huge changes in appearance. The upper half is a closed design, which is a whole, with the air intake placed below, and the frontal appearance is more like an electric vehicle.
range-extended technology analysis
Ideal Auto developed chassis control system independently. Compared with pure electric vehicles, the chassis layout of the extended-range electric vehicles is more cumbersome. In addition to the conventional motor and battery pack, an engine (range extender) must be placed for power generation; therefore, there is an additional process at the R&D technical level, and an additional range extender technology must be developed.
is equipped with a 44.5kWh ternary lithium battery pack. Because the ideal L9 is a full-size SUV, the battery pack is relatively large, with an available battery capacity of up to 39.2kWh, the CLTC pure electric range is 215KM, and the most stringent WLTC pure electric range is 180KM.
Ideal L9 is equipped with a self-developed and produced four-cylinder 1.5T range extender. Ideal ONE's 1.2T three-cylinder range extender has become history. It uses deep Miller cycles and high compression ratios, and the thermal efficiency reaches 40.5%, and the system efficiency is also 6% higher than the previous generation. In actual experience, the stability and noise and vibration when starting the cold car are suppressed very well. Ideal Auto has indeed put some effort into it.
Since the range extender does not participate in the drive, only responsible for power generation, when the power consumption is low, the power generated by the range extender can be stored in the power battery, and you can experience the experience of an electric vehicle even if there is no charging conditions.
The maximum driving power of the whole vehicle is 330kW, the maximum torque of is 620N·m, and the acceleration of 100 kilometers can be achieved for 5.3 seconds, which is equivalent to the power output of the fuel vehicle BMW X5 3.0T engine, which is very powerful. The 5.3-second body feeling of an electric vehicle is much more exciting than that of a fuel vehicle. The combined support of the
44.5kWh battery pack and 65L fuel tank, the CLTC comprehensive range of Ideal L9 has reached 1315km.
range extender technology is divided into pure electric mode and hybrid mode. Pure electric mode is a pure electric vehicle. The range extender does not start when the threshold power is not reached. Taking Ideal L9 as an example, the pure electric range of about 200KM meets a few days of commuting to and from get off work. After arriving at home, the range extender can not be started most of the time except for long-distance travel. The disadvantage is that compared with pure electric vehicles of the same size, the range is shorter and the charging frequency needs to be increased.
Ideal L9 cancels the traditional LCD instrument panel and replaces it with the HUD head-up display and the LCD display on the steering wheel. It is another design innovation. It can be used to read gear and driving information through the touch screen.
range-extended technology related design
has a 3.5-kilowatt external discharge function, and can directly discharge external discharge with an adapter. It is extremely friendly to friends who like to camp, which is equivalent to a "giant power bank".
is the charging port on the right rear, and the fuel tank port on the left rear, so the division of labor is clear. The extended range technology seems a bit cumbersome, but as far as the current domestic charging conditions are concerned, the coverage rate of charging piles is not wide enough. For example, there are still risks in charging for long-distance travel. In addition, the charging time is too long to affect travel efficiency.
Ideal L9 Although it is an electric car that can be refueled, it has the same driving experience as a pure electric car. There is no need to ignite the car when getting in, and directly use the electronic gear shift to drive the vehicle.
summary
So much about the analysis of Ideal L9 range-extended technology. The editor believes that range-extended technology has remained very popular in recent years. Many new energy vehicles are also using range-extended hybrid technology. Each product has its advantages and disadvantages. Just choose according to your actual needs.
