Zhang Xiaoxiao Beijing reports He Fang of our newspaper reporter's trainee
Next month be about to the new power of large-scale delivery builds car head enterprise to represent -- power horse car, cause attention again.
On August 25, in Chengdu academy of power horse car, car of trial assembly of EX5 of a power horse produces on fire spontaneous combustion. 26 days, power horse car publishs official statement to say, this car is a car of inchoate trial assembly that passes ruinous test many rounds, already entered the order that tear open solution, demolished circuit protector and ministry sub-unit, but fail to be finished in time tear open solution entirely, short circuit of electric equipment component causes fire.
But, this one statement can't give up the outside all misgive to power horse: What is the specific reason of spontaneous combustion? Whether to concern with batteries? Whether can sequel affect consign?
To this, 27 days, reporter of report of 21 centuries economy covers power horse car solely relevant personage, get farther response " this on fire accident and batteries report core have nothing to do, exist really discard as useless car tears open the phenomenon with solution non-standard flow, but sequel won't affect consign. But sequel won't affect consign..
Incident of power horse spontaneous combustion, it is not small blow to building company of car new power and car of new energy resources undoubtedly.
New power builds a car to be before consign, character and safe question are crucial, the doorsill of electric car is looked like very low, actually from core the security angle of 3 cables technology and product looks, doorsill actually very tall.
Can you deny influence pay?
As build car new power to represent one of companies, in light of the model information according to the exposure before this, the actual strength of power horse is not poor. But after appearing about the negative news of batteries, consumer generated doubt inevitably to its 3 cable system, analysis of the personage inside course of study says, this perhaps can affect the delivery process of power horse.
"We won't be in commonly truckload above the durable test that does ruinous experiment and so on, this is not actual, and finish commonly once all sorts of experiments discard as useless, the car is to won't be burned rise, otherwise the car of hundreds of experiments of car plant must do safe processing. So the statement of power horse resembles morely is public relations term. " on August 26, an in-house personage of dynamical cell industry reports to 21 centuries economy the reporter expressed his doubt.
This personage inside course of study thinks at the same time, power horse was taken out " discard as useless trial assembly car " this one relatively far-fetched view, because it is very difficult,from card perhaps this has the security of igneous car.
To this, the response that power horse aspect gives out is, what this incident involves is inchoate discard as useless trial assembly car, the exterior and interior used many trial-produce spare parts, the ruinous experiment that has experienced before this basically shows the relevant overload of respect of electronic electric equipment experiments.
On August 27, what power horse admits oneself tears open solution flow is non-standard. "Whole test uses car of more than 400 tests in process of test and verify, among them partial part needs to disassemble retest its wear, because the test below this part circumstance discards as useless,the car is not one-time tear open solution completely to end. Because test car amount is more, bring about discard as useless the problem of keep long in stock on test car occurrence processing, fail to press provide seasonable service and deposit at discarding as useless vehicle is special park field. " the personage tells 21 centuries economy reports a reporter related power horse.
The spontaneous combustion accident that produces this, not be the first accident that builds car new power to appear before consign any more. Colourful came on June 28 ES8 consign before today, ever also had appeared the collision accident that car develops greenbelt.
"Hitting a car is bagatelle, on fire is an important matter. Traffic accident involves the action that the person handles, often the driver's responsibility wants a few bigger; And the car stops over on fire, the problem that is a car. " one is familiar with the personage inside the trade that makes company of car new power to tell 21 centuries economy reports a reporter.
The personage inside afore-mentioned course of study thinks, reason meets this be related to produce negative effect to the large-scale delivery of power horse. "It is trustful feeling can drop the client on one hand, on the other hand, the reappear is similar accident after consign wants compensate to pay, and bothered to moment. And bothered to moment..
But power horse expresses, already found out accident of this on fire and batteries report core to have nothing to do. This second move igneous car belongs to inchoate test car, did not carry the electric core that place of prospective consign car uses to configure.
The consign car of future of power horse car will purchase the VDA report core of high energy density entirely, the manufacturer that can supply VDA report core for Weimadi at present is Ning Deshi god of force of acting, Tianjin and Suzhou world capacity. The strict test that the electric core of all batteries supplier needs to pass power horse with modular group evaluates future and severe exacting safety checks.
On August 27, power horse aspect expresses, "Check through preliminary platoon, on fire reason and consign product have nothing to do, to follow-up consign the plan does not have an influence. To follow-up consign the plan does not have an influence..
New power of trial of 3 cable technology builds a car
Last week " the arctic that find light puts house on the ice " the technology recommends an activity in, the engineers of power horse are right thirdly electric system made more detailed introduction.
Before introducing a technology, power horse shined above all group of oneself research and development: Group of 3 report research and development exceeds 500 people, 80% come from general, extensive inferior wait for mainstream enterprise, the GVDP with current to the steam on mark system of research and development.
Power horse the characteristic with 3 cable the oldest system is " platform is changed " . Above all, power horse compose built AJAX of platform of an electric car, first model EX5 is relied on namely at this one platform, road clearance sky carries highest can amount to 174mm, facilitating batteries storehouse layout. Introduce according to personnel of power horse research and development, if future goes well, power horse still can rely on this one platform, derive the model such as pure dynamoelectric SUV, MPV.
And the platform of batteries bag technology is changed, make power horse OK and compatible group of the electric core that accords with international standard standard, model, namely the product of the mainstream batteries supplier such as capacity of world of god of force of times of OK and compatible Ningde, Tianjin, Suzhou.
In the meantime, light the energy density that quantifies a technology to include power horse battery promoted 4% , decrease heavy 17% , system of independent circumfluence liquid cooling can make sure batteries bag comes in 50 ℃ - temperature stability maintains below the environment of 30 ℃ , limits of electric core difference in temperature control is in 2 ℃ of ± less than.
The electric drive system of power horse was adopted tall compositive spent plan, wait for distribution of inverter, high pressure, compressor, compositive drive axle to be equal to all closing almost the application at respect of 3 report strong report, compositive between dynamical assembly. This saved the bulk of electric drive system, "Below the circumstance of van, power horse EX5 still can install in forehead 60 litres store object space, and model of this drive after normally the circumstance falls to have only just can come true. " a personnel of power horse research and development tells 21 centuries economy reports a reporter.
Anyhow, add in the technology of 3 cable system hold below, power horse took out good dynamical data and add boat data: Peak value power exceeds 160kw, 315N.M of peak value torque, 100 kilometers quicken 8.5 seconds, the version batteries capacity of 460km of add boat course of development is 57kWh only.
In the final analysis, "Combustion probability " one of risks that are car of new energy resources all the time, lead agitation to be like tesla, also must face one picket the spontaneous combustion of another picket or incident of postaccident on fire.
On August 22, a Model S is on new jersey freeway on fire, tesla immediately response says, reason of this be related is by ahead car the spare parts drops cause, emphasize " do not have what model to be able to be retreated in the whole body in such accident temporarily, and the data of course of development of accumulative total travel of the 7.5 billion kilometer that advocates peace to be offerred with its from 300 thousand tesla cars shows, the probability of tesla model on fire is lower than benzine car 10% . The probability of tesla model on fire is lower than benzine car 10% ..
Of course, analysis of the personage inside afore-mentioned course of study says, the aptitude examine and verify that labour believes the relevant section such as the ministry to produce car of new energy resources to building car new power is gotten very strict, the group sex accident that one of reasons worry about to combustion probability is caused namely.
"Once appear group sex accident, traditional car look forward to can take out the way to deal with a situation, build car itself newly to flow without cash, facing such problem is very flimsy. " afore-mentioned personages express finally.
