Skyline ME5 is an engine/range extender in dongan power. The range extender is a naturally aspirated four-cylinder engine, 1.5L, and dongan power is the supplier of 1.2T three-cylinder engine of Li ONE. In contrast, ME5' s four-cylinder engine is more stable and NVH is better. More than 1.5L has been loaded on Li ONE.
Sky ME5 has a maximum power of 72kW. With a battery pack of 30.6kWh, the comprehensive battery life of NEDC can reach 10 12km. It has two versions: Sky 10 12 and Sky10/2 Pro. The difference between them is that the professional version has ACC adaptive cruise and LKA lane keeping.
Not long ago, this 1.5L range extender won the title of "Top Ten New Energy Power in China", and the DAM 15KE range extender assembly won the title of "China Power Innovation Pioneer", which has been installed on Sky ME5.
Skyline iMES intelligent extended range system adopts Atkinson cycle and high compression ratio to improve thermal efficiency; Through DLC coating anti-wear technology, mechanical loss is reduced and fuel economy is improved; Through the technology of central intake/exhaust DVVT and external EGR, the emission of the whole machine is improved; Through the direct connection between all-aluminum fuselage and crankshaft, the compact and lightweight design is realized; By using high-efficiency permanent magnet motor, calibration and optimization, the efficiency of extended range system is improved.
Its innovation lies in its self-developed power domain controller (VBU), which integrates vehicle controller (VCU) and battery management system (BMS), and can better manage three electric systems. It is a cross-domain control electronic and electrical architecture.
The new car system is based on the self-developed iMA intelligent digital architecture, and has the ability to upgrade software and hardware OTA. In terms of cars, Sky ME5 also has its own uniqueness. The in-vehicle system is an Android system, which is similar in style to an Android smartphone, making non-Apple users feel more friendly. In the actual operation process, it is relatively smooth and there is no obvious jamming phenomenon. Man-machine interaction is also very easy to use, voice window opening, online song ordering and continuous dialogue are all very convenient to use. In addition, the car will also be equipped with intelligent AI assistant, face recognition, intelligent welcome lighting interaction and other functions, and the cost performance is still very high.
Skyline ME5' s assisted driving system includes 22 sensors. Through the fusion of vision and radar perception, ICA intelligent cruise, TJA traffic jam assistance and other 13 auxiliary functions are realized, and intelligent driving in full speed domain is realized under closed roads.
In terms of batteries, the battery core of the skyline ME5 comes from Funeng Technology and adopts NCM532 ternary soft package, with a more balanced ratio of nickel, cobalt and manganese. Theoretically, the fire probability will be lower than NCM8 1 1.
In addition, the skyline ME5 has two modes: pure electricity and hybrid oil and electricity. When the power is sufficient, pure electricity is preferred, and the motor directly drives the vehicle. When the hybrid gear is selected, the engine acts as a generator to continuously supply power to the battery, and then the motor drives the vehicle. It can't realize the parallel connection of engine and motor, which makes people feel like an electric car.
Written at the end: On the whole, the iMES intelligent extended range system developed by Skyline ME5 is still rare in the automobile industry, which may be the reason why it has become a pioneer in innovation in the field of new energy, and it is also a major technical highlight worth mentioning in the future.
