2023 Shanghai Auto Show： Ideal Autopilot and Pure Circuit Line
[car home Information] On April 18th, 2023, LI released the "Double Energy Strategy", which will fully exert its strength in "intelligence" and "electric energy". In terms of "intelligence", NOA navigation-assisted driving in the ideal city of AD Max 3.0 will be launched in the second quarter, and the landing push in 100 cities will be completed before the end of the year. It is worth mentioning that the NOA navigation and driving assistance system software and services in the ideal city of AD Max 3.0 are free for life, and its "assets" will also be fully reflected in the second-hand car transaction.
In terms of "electric energy", LI has launched an 800V ultra-charged pure electric solution, officially entering a new stage where "extended range electric" and "high voltage pure electric" go hand in hand. By 2025, the product layout of "one flagship model+five extended range electric vehicles+five high voltage pure electric vehicles" will be formed. At the same time, at the press conference, LI and Contemporary Amperex Technology Co., Limited signed a "Comprehensive Strategic Agreement", announcing that LI’s first pure electric vehicle will become the first vehicle equipped with 4C Kirin battery in the world.
"In the’ intelligent’ part of the’ dual-energy strategy’, the ideal intelligent driving has officially entered the 3.0 stage. According to the official, its release will make the ideal model completely free from the dependence on high-precision maps, and it can perceive, make decisions and plan in real time like a human driver, thus realizing autonomous traffic in complex urban scenes and bringing users a truly usable intelligent driving system. Lang Xianpeng, vice president of intelligent driving in LI, said.
"Under the’ electric energy strategy’, LI released an 800V super-charged pure electric solution, which combined the high-voltage electric drive system based on the third-generation power semiconductor, the battery with 4C charging capability, the thermal management system with wide temperature range and the 4C super-charged network to realize the charging efficiency of’ charging for 10 minutes and cruising for 400 kilometers’ from 2G to 5G era. Ma Donghui, president and chief engineer of LI, said, "In the future, extended-range electric and high-voltage pure electric will work in parallel to bring users a complementary energy experience comparable to that of fuel vehicles, and finally realize the goal of replacing fuel vehicles on a large scale."
LI delivered a total of 52,584 new cars in the first quarter just past, an increase of 65.8% compared with the first quarter of 2022. Liu Jie, vice president of LI Commercial, said: "Up to now, the cumulative delivery volume in LI has exceeded 300,000."
Ideal intelligent driving enters the 3.0 era
In the aspect of intelligent driving, LI insists on full-stack self-research. The official said that the ideal intelligent driving has entered the 3.0 era, from high-speed scenes to urban scenes.
LI has used three neural network large model algorithms: static BEV network algorithm, dynamic BEV network algorithm and Occupancy network algorithm to restore the urban navigation assisted driving algorithm, and used NeRF technology to enhance the Occupancy network algorithm to achieve higher accuracy and details.
Static BEV can still fill the road structure when some cameras are blocked and lane lines are blurred, which solves the real-time problem of high-precision map data.
Dynamic BEV can track and perceive the distance and speed of the object stably when the vehicle appears in the field of vision of multiple cameras at the same time, which makes the dynamic BEV neural network have a certain "brain supplement" ability.
Occupancy network algorithm can model the physical world in which we live in data, and restore the real scenes of the physical world through pure vision, such as trash cans on the road, temporary construction signs and other "general obstacles". On this basis, the use of NeRF technology further improves the resolution of Occupancy at a long distance and makes the system more powerful in perception.
Based on the perceptual results of the above three neural network large model algorithms, the system will output the trajectory prediction results of all traffic participants around in real time, which can provide accurate information for users in decision-making planning of complex urban scenes.
Solution of 800V Ultra-charged Pure Electricity
At the press conference, LI put forward the solution of 800V super-charged pure electricity. This scheme includes an 800V high-voltage electric drive system based on the third-generation power semiconductor silicon carbide technology, a battery with 4C overcharge capability, and a full-stack self-developed thermal management system, which improves the charging speed and energy efficiency at the same time, so that users can obtain higher charging efficiency and longer cruising range in various environments.
It is reported that LI’s new generation self-developed electric drive system will be built with 800V silicon carbide power module. The application of the third generation power semiconductor Sic technology is the key to improve energy efficiency, and the capability of SiC chip also determines the upper limit of electric drive performance. At the same time, the 800V silicon carbide power module independently developed by LI can support up to 480A current output. The volume advantage of the self-developed power module combined with the multi-component integrated design of the motor controller makes the volume of the motor controller compressed to less than 4L and the power density as high as 62kW/L, thus reducing the volume and weight of the electric drive system and further optimizing the space and energy consumption of the whole vehicle.
In addition, in order to solve the problem of charging high-voltage electric vehicles on low-voltage charging piles, LI innovatively provided a deeply integrated boost charging solution. Using the inductance characteristics of motor windings, the electric drive system can be transformed into a step-up power supply, allowing users to get a fast charging experience of up to 150kW on charging piles with a voltage of 750V and below, and the highest charging efficiency can reach 98%. LI self-developed high-voltage electric drive system adopts the third generation silicon carbide power module and deeply integrated boost charging function, which not only improves the energy efficiency, but also has the function of fast charging and recharging covering the whole scene.
Intelligent charging network layout
LI officially launched the "Ideal 4C Super Charging Station" and the super charging network. Different from the traditional idea of taking a single charging pile as the product, the "Ideal 4C Super Charging Station" takes the whole station as the smallest module of product operation, and realizes intelligent interaction, intelligent operation and intelligent security by deploying four cameras and an intelligent sensing chip with computing power of 128TOPS. In the future, the ideal 4C overcharging station will also realize the real-time synchronization of station information with car and mobile App.
At the same time, the LI 4C super-charged pile can reach the maximum output power of 480 kW, and with the ideal 4C model, it can quickly replenish energy by charging for 10 minutes and increasing the battery life by 400 kilometers. Combined with the power flexible distribution function of the station, the output power of each charging pile can be flexibly distributed based on the utilization rate of the charging pile.
In order to make more users in LI enjoy a more convenient charging experience, the first batch of 25 ideal 4C overcharge stations will be put into trial operation one after another before the end of May. The ideal 4C overcharge station will be open to all new energy vehicles, and the overcharge network will be rapidly improved in the next three years. By the end of 2023, LI aims to build more than 300 high-speed overcharging stations, covering 70% of the high-speed mileage in the four economic belts of Beijing-Tianjin-Hebei, Yangtze River Delta, Greater Bay Area and Chengdu-Chongqing, and the national high-speed coverage rate is expected to reach 40%. By 2025, the goal is to build more than 3,000 overcharging stations, which will cover 90% of the country’s national high-speed mileage and major cities.
Vehicle planning: 1 flagship vehicle +5 extended-range electric vehicles +5 high-voltage pure electric vehicles.
Next, LI will also enter a new stage where the extended range keeps pace with pure electricity. By 2025, LI will have a product layout of 1 super flagship model +5 extended-range electric vehicles +5 high-voltage pure electric vehicles.
"ideal new MPV spy photos"
The first pure electric vehicle in LI will be a pure electric MPV, which Li Xiang calls a whale (aircraft carrier), and there are five sharks (ships), which should be cars or SUVs. Previously, car home reported the spy photos of the ideal new MPV model. It is understood that the car will be rolled off the assembly line in July, officially mass-produced in September, and is expected to be listed in 2023. (Text/car home zhang xiaodan)
