avita has taken the lead in formulating new standards for the intelligent range-extended vehicle industry.

on september 13, the "top of kunlun" extended range technology development forum, jointly sponsored by the china automotive engineering research institute and the china electric vehicle 100 forum and supported by avita technology, was held in kashgar, xinjiang. more than 20 think tank experts brainstormed on hot topics such as the market prospects, evolution trends, and user experience of extended range technology. the china automotive engineering research institute and the china electric vehicle 100 forum will jointly release a research report on the extended range industry and refine the new standards for extended range technology.

in his keynote speech, hu chengtai, vice president of avita technologies, said that avita's fully self-developed kunlun range-extended vehicle has achieved technological breakthroughs in many fields. the kunlun range-extended vehicle is considered to be a truly leading-generation intelligent range-extended vehicle, with a clear generational gap from existing range-extended technologies, providing a successful case for reference for the industry's technological leap.

as more and more automakers enter the new track of extended-range technology, competition has been stimulated, but some long-standing problems have also aroused public doubts. the extended-range field urgently needs new standards that gain broad industry consensus. to this end, the china automotive engineering research institute, the china electric vehicle hundred people's association and avita technology jointly issued the "top of kunlun - extended-range technology development initiative", which recommends redefining the new standards for extended-range technology.

first, at the top-level design and theoretical cognition level, the advancement of technology should not be determined solely by the power form, but should improve the overall performance and user experience through continuous technological innovation, explore the deep integration of extended-range technology and intelligence, and solve problems such as power attenuation of extended-range vehicles under extreme working conditions through more intelligent power control, accelerate technological breakthroughs, and promote the innovative development of extended-range technology.

secondly, extended-range vehicles should adhere to a user-centric approach, with the aim of reducing user costs and improving user experience, continuously reduce vehicle costs, and provide an experience as quiet and comfortable as that of pure electric vehicles.

third, automobile companies should fully recognize the cornerstone role of key components in the development of extended-range technology, promote the high-end, intelligent and specialized development of key components such as extended-range engines and batteries, and achieve stable power output, unlimited use, and safer driving experience of extended-range vehicles through the specialization of key components.

fourth, we must promote the construction of industrial standards, specifications, and technical certification systems, accelerate the formulation of industrial standards, especially in key modules such as engines and batteries, continuously promote specialization and standardization, achieve higher vehicle economy and driving safety, build a fair, open, and pragmatic industrial platform, and establish a sound evaluation system.

the forum invited many experts, scholars and technical masters in the field of new energy vehicles. they combined their own research fields and focused on the pain points of extended-range electric vehicles that ordinary consumers are concerned about, put forward their insights, corrected and interpreted some fallacies and prejudices, and expressed highly forward-looking views, setting the tone for the future development direction of extended-range technology.

experts at the meeting believed that the cognitive bias of "extended range is backward" actually comes from the low level of existing extended range technology and poor product experience, which has led to misunderstandings and prejudices among users. the standard for judging whether technology is advanced or backward is product experience and user perception rather than technical form.

in addition, the future development of range-extending technology will be closely related to the real demands of users. you cannot make a good range-extending vehicle simply by "taking what you want". you cannot "assemble" a good range-extending vehicle using the parts of traditional fuel vehicles. leading range-extending technology must be developed with targeted special projects, which is a great test of the core self-research capabilities and system strength of car companies.

of course, users' perceptions vary. good range-extended technology must be based on three major principles, namely "powerful power, quiet driving, and efficient and worry-free". if these three points are achieved, this range-extended system can be considered an "excellent student".

avita, which insists on full-stack self-research, applies top wisdom to extended-range technology and successfully creates the kunlun extended-range, bringing users a new extended-range experience that is extremely powerful, extremely quiet, and extremely worry-free. its innovative achievements won the recognition of the experts attending the meeting.

in order to solve the problem of weak power supply of extended-range vehicles, avita technology and catl have jointly developed a 39kwh super hybrid battery, which focuses on improving the battery discharge capacity, achieving the industry's highest peak discharge rate of 9c for full charge and 7.7c for power supply. it only takes 15 minutes to charge from 30% to 80%. with the highest peak output power of 100kw in the same class, the special generator for extended-range vehicles can truly achieve power with or without electricity. at the same time, kunlun's extended-range technology can bring strong power preservation capabilities, ensuring that the battery power will always be exhausted after the fuel during daily driving.

in order to provide users with a quiet and comfortable driving environment, avita's self-developed kunlun extended-range he1.5t supercharged dedicated engine is equipped with the world's first electronic oil pump technology and unique shutdown piston active control technology, which successfully controls the sound pressure inside the car during idling charging to 35.7 decibels, and the quietness is comparable to that of pure electric vehicles.
