The capital shamrock of after autumn, relaxed.
Colourful comes to ZhongGuanCun ideal edifice before experiencing central door, the colourful with a brand-new platoon comes ES8 is awaiting Sunday run travel.
Colourful comes the time that ES8 orders Zhi Jiajun hand to went up to had crossed nine beforehand from open, the time that if Cong Wei comes,the car establishs also have up to now 4 years.
In the spring tide building a car of this round of billowy, it is carried this old expectation, call its high-powered intelligence on this meaning dynamoelectric 7 SUV, come to colourful the car more advocating is the 3rd shift give a space.
It is with the user this.
How are this explained?
Trying before driving, colourful comes the car demonstrated one key publicly to add report to serve systematic NIO Power above all, the means that will experience central imitate user in colourful comes through colourful mobile phone PP undertook report serves an experience bolting adding, in come through colourful APP makes an appointment after the success, the car that there can be special colourful to serve personnel to undertake appending report to need inside a few minutes undertakes the phone affirms, in the service personnel arrives after appointing the position, need to carry a mobile phone only long-range open door, colourful will serve personnel to be able to undertake to car report serves adding.
ES8 embarks can change electric framework, the spot demonstrates to pass colourful to exchange a power station inside 3 minutes achievable change report, this one process, colourful will serve personnel the operation is fluent.
Be worth what carry is, colourful will add electric commissioner to also belong to colourful to come employee, this can assure to be in the process that append report safety and efficient.
Same mobile interconnection experiences, colourful will also can apply to car service. The service cloud that colourful comes to also can come to colourful car of center, maintenance center, consign center, service, ES8, colourful comes the service Internet that commissioner and user join become a wisdom.
The high-powered intelligence on a real significance is dynamoelectric 7 SUV, can be ES8 accomplished quicken boat of fast, intelligence, add not to have pressure?
From the Wei Laizhong that is located in Beijing ZhongGuanCun the heart sets out be pressed down to Gu Beishui, whole journey 141 kilometers, can divide roughly for 3 kinds of road condition, the city is embraced, high speed and hill roadbed satisfy Kuang Zhongzhi that drives daily to drove Jun Jin to go originally deepness tries drive an experience.
Regard a mobile life as the space, ES8 has 3010 millimeter wheelbase, modelled 3 7 agile spaces of 8 kinds of mode, initiate " queen deputy drive " obtain along with the car female media agrees reputably.
Pressing down whole journey actually to Gu Beishui from Beijing 141 kilometers drive in the process, on the car 4 people, system of air conditioning, entertainment is regular open, drive mode is regular pattern + athletic mode mixes use, and among a few times to have urgent quicken the colourful below the circumstance to come is boat of ES8 actual add behaved how?
The odograph before from the Wei Laizhong of Beijing ZhongGuanCun the heart sets out shows add boat is 345 kilometers, travel serves an area to Beijing close cloud, course of development is odd 252 kilometers, actual travel course of development is 78 kilometers, use up course of development to be 93 kilometers, what the attention wants here is in high speed a section of a highway average travel speed per hour is horary 90 kilometers crowd an a section of a highway average travel speed per hour is horary 30 kilometers left and right sides.
From Beijing close cloud serves an area to press down whole journey to be high speed a section of a highway to Gu Beishui, odograph shows add boat is 252 kilometers, travel is pressed down to terminal Gu Beishui, course of development is odd 177 kilometers, actual travel course of development is 63 kilometers, use up course of development to be 75 kilometers, average travel speed per hour is a section of a highway of whole journey high speed horary 90 kilometers.
Integrated and character, whole course is real course of development 141 kilometers, colourful comes ES8 uses up course of development actually to be 168 kilometers, whole process colourful comes ES8 loss course of development is 17% , according to NEDC integrated operating mode 355 kilometers, in high speed (speed per hour is horary 90 kilometers) + embrace a travel of urban a section of a highway (speed per hour is horary 30 kilometers) , boat of add of Wei Laishi border is 294 kilometers about.
Need a specification here is, come in colourful APP has option of calculator of an ES8 course of development in tool of menu love a car and service option, choose travelling speed 90km/h, the temperature outside the car 40 ℃ , air conditioning is opened, hub dimension 19 inches, its show wait for course of development of fast add boat to be 285 kilometers.
Can say numerical value of computation of calculator of this one course of development is quite exact.
To pure electric car, batteries safety and batteries add boat service life problem is user place care all the time, in the meantime, raise electric car to protect a value to lead what will drive electric car to gain ground, one of among them core problems are the rate of low damage cost that how solves batteries.
Colourful comes from proceed with of administrative batteries complete lifecycle, defer batteries attenuation, ensure the performance inside batteries complete lifecycle is smooth.
For this, whole report store can the use that design of research and development wants to satisfy step of high-powered car plan on performance of safe, power not only, consider follow-up ladder even second the requirement that use, come true to change report quickly.
Vice president of engineer of motivation of colourful incoming telegram, colourful comes Huang Chen of CTO of drive science and technology east express, colourful comes ES8 used VDA square model electric core, whole report store can the system has powerful safety and fast property, dynamical cell system is inside complete lifecycle performance is smooth, of ES8 batteries protect watch to be able to be folded reveal its advantage.
Whole system uses compositive formula modular design, and put forward " 3 vertical 3 horizontal strokes " safe structural frame, the domain such as the system of the system of BMS batteries management in the key, liquid cooling constant temperature, sudden fit that change report is had banner and complete core technology, ensure whole system has extremely tall wear and security.
Colourful comes because future wants a few times to carry the battery of same type with this model,the batteries form that ES8 of the first car used a 70kw only is group, in order to make sure all models support the unified pattern that change report.
Have to make dynamical cell is inside complete lifecycle outstanding and smooth function output, be about to control the consistency problem of batteries as far as possible, defer batteries attenuation, had done for batteries constantly maintain.
Among them, the abhorrent sex of electric core the energy management system that a priori decided to batteries is wrapped.
Huang Chen east say " interval of temperature of density of cycling life, power, energy density, job, safe, cost is the mainest parameter that judges batteries technology.
Nevertheless, cannot achieve perfect balance first and last, if want to promote some the parameter of the respect, be destined to be able to sacrifice the parameter of other side.
Because this colourful comes when research and development,often want to come true according to specific requirement allocate.
The technology of liquid cooling constant temperature that Wei Laicai uses has heat exchange coefficient tall, cooling, heat rate is rapid wait for a characteristic, can help batteries come loose not only hot, OK still more essence of life undertakes definitely lukewarm accuse, help batteries heat preservation.
When the job, the temperature of electric core delivers a model group and cold board osculatory bottom, mat of repass heat conduction passes liquid cooling board, the wall outside liquid cooling board conducts quantity of heat to cooling fluid again, achieve fall for warm end.
Heat process vice versa.
The system of BMS batteries management that colourful comes to has SOC essence to be measured definitely calculate with SOH of estimation, outstanding balanced strategy, real time beforehand the character such as monitoring of appraise, batteries and real time early-warning, ensure batteries function to stabilize output thereby, ensure dynamical cell grows life.
And change of the healthy level of electric core, external temperature and 3 filling discharge fold is function of SOC of noumenon of influence report core main factors.
Pass BMS beforehand appraise SOC, its purpose is to be corrected as far as possible measure an error, promote precision through advanced soft hardware function, reduce loss sex: One, promotion sensor measures precision; 2, the processing capability that promotes chip; 3, powerful algorithm handles ability.
Shellfish pulls the Yi Sha that the sensor of packets of whole electric current that colourful comes to uses Germany to import sensor, voltaic sampling precision is tall, the Ying Feiling that pool of colourful incoming telegram manages a system to introduce newest generation advocate chip, the capacity of 32 data processing can be had on hardware, can provide higher operation capability.
The low temperature of lithium battery charges is a difficult problem forever, the temperature with electric the most comfortable core is controlled in 25 degrees. Colourful incoming telegram store can buy of inter block of every batteries model has sensor of temperature of 3 report core, implementation temperature detects accurately and can control.
According to Huang Chen east introduce, overall and character, colourful comes the battery life of ES8: Fill discharge loop attenuation 1500 times not under 80% , support of the component that change report changes report 10000 times, 130 seconds last 590 degrees baked wheaten cake does not have safe problem, from freedom of 1 meter of height falling body is on armor plate, batteries bag structure is whole, the function is normal, time of seawater of 3.5% sodium chloride immerses test, batteries is not had into water, the function is normal, 5 - 40 ℃ and 85 ℃ cold heat are alternant quiet place 8 hours, batteries function is normal, bear 200KN level keep long in stock does not have safe problem.
In intelligent interconnection respect, colourful comes ES8 passes an artificial intelligence robot that the name is NOMI to have car user relevant couplet.
Look from the exterior, NOMI resembles a small acoustics, carried screen of a LED, UI can present different expression symbol according to different setting.
When Zhi Jiajun from left open the door when getting on a car, NOMI can open the door to turn at the same time from tendercy first, had shown with expressional symbol.
Trying all the way in driving, zhi Jiajun ever dallied with NOMI for many times, NOMI system is compositive speech is alternant system and intelligent affection engine, say when Zhi Jiajun the weather is hot, with respect to meeting side you adjust air conditioning, say hunger when Zhi Jiajun, NOMI meeting enumerate gives a series of dining room and automatic computation distance undertakes navigation, still can help you and friend be patted oneself even.
In using a process actually, NOMI system response is fluent, intelligence changes rate taller, because carried the platform that colourful will come to cooperate with Ying Weida to call NVIDIA Drive CX,this is, it can realize the function that learns automatically, can the computational platform function of all implementation recreation is compositive together.
On this platform, happy system can compare Che Zaiyu more fluent before, the indication meeting of graphical picture is more perfect, 3D navigation or map navigation will be more accurate.
NVIDIA Drive CX comes in colourful the action among ES8, provide a hardware not merely, can provide more services at the same time, can make an user ceaseless upgrade the car holds tube-shaped part of computer science department.
Study of look forward to of this worth while and traditional car and draw lessons from.
Drive in intelligence respect, colourful comes ES8 supports ACC to decide fast cruise system only at present, through steering wheel left key-press can bolt start.
The position is colourful comes on the side of in this key-press the NIO Pilot key-press of obligate, NIO Pilot is colourful comes of ES8 unmanned and auxiliary drive system, nevertheless this system of short duration was not started to the user.
Nevertheless, in hardware level, colourful comes ES8 had installed 23 perception hardware beforehand, before including 3 item to photograph like the head, 4 sweep are photographed like sensor of 12 radar of 5 head, millimeter wave, ultrasonic, still have condition drives to detect inside a car photograph like the head, carry Mobileye EyeQ4 to drive automatically with fashionable dress the quantity of chip produces a model.
What tesla Autopilot 1.0 uses in those days is the EyeQ3 chip of Mobileye, eyeQ4 function promotes 8 times than Q3, power comsumption increased 20% .
Current, colourful comes ES8 had been finished many drive automatically the function checks the work, include to emulate check and close road checks. In the meantime, wei Laitong pace begins the open road that is in Beijing of American California, China and Shanghai to test a plan, offer for the user more safety and efficient drive automatically experience.
And driving automatically on the course, weilai devotes oneself to on one hand advanced and auxiliary drive the system produces the application in the car in the quantity, cooperate truckload OTA collects true path besides medium data, improve algorithm continuously; Step of L4 of ongoing also hair is voluntary on the other hand road-sense.
Introduce colourful to the drill of ES8 accuses and drive finally experience, high-powered to the first 7 SUV, colourful will be shown very self-confidently.
ES8 uses design of around double electric machinery, 4 drive, general power 480 kilowatt (650 horsepower) , total torque rice of 840 oxen · . Below athletic mode, colourful comes ES8 quickens time to be 4.4 seconds, what output character and transmission structure as a result of electromotor is different, photograph comparing quickens the benzine car with adjacent ability, ES8 gives a person to feel little a few minutes insurgent, more is dizzy with stimulation.
Undertake in hill road intense when driving, colourful comes ES8 is too curved very dovish, pass as to the net " the batholith of ES8 feels inattentive character, automobile body stability is insufficient " opinion on public affairs, zhi Jiajun's feeling is inattentive it is absolutely nonexistent, whole batholith accords with the level that be the same as class.
Nevertheless, in the time that is 4.4 seconds quickly in 100 kilometers, because Brembo caliper and the tire with 265 wide millimeter send the action of brandish, colourful comes ES8 100 kilometer / the hour comes stop to need 33.8 meters only, this is the expression of 911 level almost.
Good brake performance is the premise that the person that drive produces trust to a car.
Will colourful be worth to buy?
In the car that at present Motor Corporation of all new energy resources produces, colourful will be more outstanding.
This means it very perfect, still wait for on function of a few detail improve.
What care to everybody is long-distance drive problem, colourful comes today ES8 car advocate already 8000 kilometers drive open oneself row, set out from Guangzhou Xinjiang. The place that fuel car can reach, can Weilai arrive euqally? This the test perhaps has can have a result.
Perspective of science and technology, extremely guest spirit
" AutoR wisdom drive " be born for new car
