AutoBeta(AutoBeta.net)06/28 Report--

After a series of spontaneous combustion accidents, Xilai decided to recall 4803 ES8 and replace the power battery pack with the risk of spontaneous combustion. Judging from its cumulative delivery of 17550 vehicles to users by the end of May, the recall is wide-ranging, accounting for 27.37 per cent.

It is worth noting that Li Bin, CEO of NIO, has stated publicly for many times that electric car fire is a probabilistic event, and the fire probability is not higher than that of fuel vehicles. However, from the four accidents accumulated so far, coupled with the urgent need for a recall of 4803 ES8, Li Bin's claim has been criticized to some extent.

In addition, many netizens said that "the first batch of new cars are mice." Xilai Automobile also confirmed that the recalled model is an early production module with battery pack specification and model number NEV-P50, and the voltage sampling harness in the module may be extruded by the cover plate on the module due to individual improper direction, and the extruded voltage sampling harness skin insulation material may be worn, resulting in short circuit. Since then, the produced vehicles have been replaced by the specification model NEV-P102 module, and the internal structure of the module adopts different designs, so there is no hidden danger mentioned above.

NIO notifies the car owner by SMS and APP prompt to confirm whether it is within the scope of this recall. The owners of NIO said they had received a recall message to keep the battery below 90%.

The information shows that the power battery pack will be replaced within 2 months and will be replaced in the near future. At the same time, it is also reminded that before the battery pack is replaced, the car owner can continue to use the vehicle and keep the battery at less than 90% when charging.

The owner of you NIO said, "I dare not sleep even if I recharge at night. I stared at it until 90% and unplugged it quickly." Other netizens in the comments reminded that the charging limit can be set through the mobile phone app.

NIO officials say it is recommended that users' SOC be reduced to 90% because the lower the SOC, the lower the cell expansion and the less likely the harness will be damaged. NIO has upgraded the vehicle management software and mobile phone APP, and the maximum charge value of users in NIO home is set to 90% by default, which is more conducive to long-term battery health and safety.

But this practice has also caused controversy, meaning that users have bought a full-price electric car with a theoretical range of 355km, which can only run more than 300km at most.

As for the recall, Li Bin, CEO of NIO, quickly wrote in app: "it is precisely because we do not dare to betray everyone's trust that we do not hesitate to decide whether to recall or not." Using a better battery pack to eliminate security risks is the most expensive way, but it is indeed the most reassuring way. "

Ningde Times, a battery supplier, also issued a statement: the batch module uses a customized design, which is only used in the 4803 ES8 products recalled this time.

In order to seize the market opportunity, Xilai Automobile is much earlier in mass production and delivery than other new car-building forces, so it is questioned by the outside world that the product is not perfect. In fact, in the early days of ES8's launch, there were many product failures and imperfect electronic systems, and now they are being investigated and recalled because of frequent spontaneous combustion.

Although NIO claims that the improved battery pack is used in subsequent production, there is no risk that the voltage sampling harness will be squeezed and worn, but frequent quality problems will undermine the confidence of users and consumers. Of course, some NIO owners believe that this is a reflection of the company's responsibility to users.

Still in the face of large investment and losses, it is predicted that the recall of Lulai will lose nearly 480 million yuan. The company lost 2.6 billion yuan in the first quarter of this year and 9.6 billion yuan in 2018.

Li Bin also said that NIO is still a four-year-old company, and it is impossible to ask a four-year-old child to support his family. For this situation, Li Bin said that he is very remorseful and sad, and will continue to improve and improve. Please supervise and witness the growth of NIO together.
