Recently, a section from “enthusiastic” mass cell phone footage of electric cars on fire video was posted on the web. Characterized by an electric vehicle rear combustion in identifying the video, it was confirmed that the model vehicle easterly wind E11K Jun electric car, the combustion flame sprang from the bottom of the vehicle, for firefighters is injected to cool the fire point, fire (fire extinguisher in the plurality of sets of picture appear).
east wind E11K Jun electric vehicles in mid-October 2018 listed a total of a model, after the price subsidy of 16.8 million. Jun wind E11K based Nissan Sylphy classic cars modified platform from the overall design has not changed, length and breadth were 4665/1700 / 1540mm, wheelbase 2700mm, fully consistent with the Sylphy classic. Jun wind wind E11K electric vehicle powered by a maximum output power of 100 kW permanent magnet synchronous motor, the maximum output torque of 260 Nm. Dongfeng E11K electric car suspension and Dongfeng Nissan Sylphy, like the use of front McPherson + torsion beam structure. However, due to battery power “suspension” more low-end models in the central body welding, body height than the fuel version of the Sylphy.
by chance that the author in Wanning City, Hainan December 2019, and take over the car for network operators around the wind Jun wind E11K electric car. “Custom” price, the right policies, adequate mileage, win the approval of many operators.
in the tropical climate in Dongfang City, Hainan Island (West Coast) – Sanya (South Coast) – Wanning City (East Coast) area, net chauffeur-driven car about Dongfeng E11K electric vehicles, along with the fast charge stations around the island near the highway, use the “electricity filling up fast during the day, nighttime slow filling to full power” mode, to meet the one-way mileage 330 km mileage requirements of business operations (open cockpit air conditioning and refrigeration systems normalization).
Dongfang City in Hainan Island, more than 180 km away from Sanya City, the annual average temperature of 24deg; C-25deg; C; Sanya City, the average temperature 25.7deg; C, the highest temperature June 28 average.7deg; C, the lowest temperature in January average 21.4deg; C; Wanning City, 112 km away from Sanya City, the annual average temperature of 24 ℃.
The center multifunction display key can read the data driving motor speed (red arrow), the gear position, the mileage and the output current and voltage. After familiar east wind E11K Jun electric car driving, braking and energy recovery mode, the driver according to the driving motor speed, the speed of vehicles and to predict the actual road conditions, in order to reduce overall power consumption and the life of the brake system, and the use of fast charge up the cost of electricity.
Photo-Jun wind power wind E11K electric car cabin close-up details the various sub-systems (obtained after shooting the driver allowed).
Red Arrow: a power electronics unit (similar to the “4in1” Motor Control + PDU + DCDC + OBC assembly)
blue arrow: a power electronics unit and the drive motor common cooling pot fluid circulation line
The green arrow: the master cylinder with vacuum booster assembly (separate vacuum pumps and adapted to the cylinder group 1)
Jun wind wind electric car mounted E11K group 1 “4 in 1” electric drive control system assembly and high voltage electricity from Wuhan Lok Genesis Technology Limited. This was established in 2014, next to Dongfeng Design and Research Institute, focusing on new energy electric car parts sales and service in one company. Main business covers: board charger, DC / DC, the vehicle air conditioning compressor, a high voltage cable assembly embodiment, a charger, a charging socket.
Photo-Jun wind wind electric car adapted E11K slow charge on OBC cartridge close-up detail. Using air cooling, but without access to the drive motor and the power electronics unit common cooling circulation line, this technique is rarely used to set the amount of production in 2018 of the price range of 15-20 ten thousand yuan mainstream models.
east wind E11K Jun electric vehicle mounted battery assembly 1 57.5 kWh energy density of 160Wh / kg ternary lithium cell assembly, the NEDC life of 405 km. It found that by careful insight,Car battery management systems lack a temperature control system using passive air-cooling battery form.
Unfortunately, I could not shoot in Wanning City to the technical details of “quick-charge” Dongfeng Jun wind E11K electric car. Because in the north of Guangzhou-Shenzhen and other cities line 1, there is no east wind E11K Jun electric cars in the sale, they failed to learn in more detail, such as a battery assembly, batteries supplier information. However, random bit Baidu keyword “Dongfeng Jun wind E11K” to push the “east wind e11k Jun retirement vehicles’ information.
I have something to say:
east wind E11K Jun electric models, Dongfeng Fengshen E70 electric car can be seen as different modifications Nissan Sylphy electric vehicles. The three models of electric cars are based on fuel Sylphy models “oil power” from, so they have encountered serious case interior space is occupied. Dongfeng Jun wind E11K, Dongfeng Aeolus E70 and Dongfeng Nissan Sylphy EV, 3 electric car equipped with an electric drive system, different battery and thermal management strategies.
The picture shows the wind Jun E11K wind power electric car compartment close-up details (battery powered passive air-cooling technology).

In 2020, China’s new energy subsidies sharply sloping back and no longer on battery power density requirements. Security tends to iron phosphate lithium battery regression, tend to “811” high-nickel ternary lithium battery lower cost high-density, bulk density and improve CTP appear (no module) packaging technology, so that the competition of many depot continued surge in intensity doubled, triggering a fundamental point of terminal owners choose.
Currently, Dongfeng Jun wind E11K electric car caught fire accident no follow-up news flow out, intelligence analysis of new energy network will also actively continue to focus on this event and look forward to plantSurvey released home.

June 27, 2019, for new financing of 100 billion “repairer new forces” to Wei, in the past 1 after four consecutive burning incident occurred months, suddenly announced the recall of 4803 packages contained Ningde era provides a battery module, own production of battery assembly. Wei, vice president of Power Engineering Huang Chendong call issued “a number of issues regarding the battery recall instructions” on Wei to App.
August 13, 2019, 1 Great Wall Euler R1 electric vehicles, charging station explosion. Great Wall this manufacturing Euler R1 electric car, parked in the charging station, to confirm whether or not in a charging state (charging station configured to fast-charge the charging post pile). Great Wall Euler R1 electric car explosion in front passenger side, parked alongside the Great Wall of Taiwan Euler IQ electric vehicles. In March 2020, Great Wall Motor has not released official findings Euler R1 explosion.
Edit
August 2, 2019 in the evening, 1 cheetah in a parked state CS9 EV300 electric vehicles, in Zunyi City, Guizhou Province positively County bus company vehicle hub (formerly Terminal positive County site) and the occurrence of a fire burning. This cheetah CS9 EV300 electric cars and combustion occurs when a fire accident, the first time the fire brigade arrived at the scene and the fire was controlled. In March 2020, the cheetah has not released the findings of an official car CS9 EV300 explosion.
