2020 TODAY battery is dead or caused by smart connection module leakage

The Automobile Quality Network is China's leading platform for collecting information on defective car products and owner quality complaints, and is also the third-party preferred medium for car buyers to understand the quality status of relevant models.

During the epidemic, people's lives were greatly affected, and many people's vehicles could only be left idle. With the gradual recovery of work and production across the country, many people may face the situation that their cars cannot be started because they have not been used for a long time. This situation is not uncommon for vehicles. However, at the beginning of the gradual recovery of the economic order, within a short period of time, the vehicle quality network received complaints from more than 50 Zhengzhou Nissan potato car owners, of which 49 complaints were against repeated power outages of the potato battery in 2020, causing the vehicle to fail. start up. Many car owners say that it is difficult to find this hidden problem without going through this special period, and the occurrence of this problem is closely related to the product defects of the two models of Tudou's dumper system. Mr. Wu, a vehicle owner from Shanxi, reported to the Vehicle Quality Network that, because the vehicle did not travel frequently during the epidemic, when Mr. Wu wanted to drive, he found that the remote control key could not open the door and the vehicle could not start. Only then did he know that the battery was dead. Since the vehicle had not been moving for several days, Mr Wu did not care too much at first. He found other vehicles and started driving for about 200 kilometers to recharge. However, after a three-day stop in the basement, another entire vehicle was dead, which caused the alarm. At present, Mr. Wu has learned that it is not accidental that the owners of more than 2020 Tudou cars owned by the group have encountered this problem. Among the complaints received by the vehicle quality network, the vast majority of vehicle owners reported that the vehicles could not be started after 2-3 days of parking, which caused great inconvenience for travel during the epidemic. As we all know, during the long-term parking of the car, the battery does power off, because even though the car is off, many electrical devices still consume power. This is called the quiescent current, but the power consumption is very low. So, how many days does a car have an abnormal battery charge? Generally speaking, 15-30 days is within the normal range. The more electrical equipment used in a vehicle, the shorter the days of storage. If it is true as stated by the owner of Duda, if the battery power loss problem occurs after the vehicle is parked for 2-3 days, it is necessary to detect whether there is any leakage problem in the vehicle line by measuring the static current. A simple measurement method is to connect an ammeter to the battery, the car lock anti-theft device is in a normal working state, and all electrical equipment is in a sleep state. The current measured at this time is quiescent current. Under normal circumstances, the quiescent current of vehicles with less electrical equipment should be less than 10 mA, while the quiescent current of more vehicles should be about 20-30 mA. If this criterion is exceeded, the leakage of a vehicle can usually be determined. Of course, the leakage mentioned here is not entirely a circuit problem, it may be caused by some electrical Caused by excessive static current of the equipment. However, the vehicle quality network learned from some owners and netizens of Tudou that the static current of vehicles that lost power after detection was as high as 1A, far exceeding this standard. Complaint data shows that among the complaints related to battery failure received by the distribution network, except for one in the 2018 model, the rest are concentrated in the 2020 model. What's more "coincidental" is that among the current complaint models, there are only 2.5-liter cars, 4WD Deluxe Edition and 4WD Ultimate Edition, which has attracted people's attention. In addition to the influence of sales factors, whether these two models are in the relevant configuration or whether the "real culprit" that caused the leak is worth investigating. According to market news, the biggest difference between the 2020 and 2018 models is the upgrade of configuration. As shown in the figure, the new Tudou upgrades some models of multimedia touch screens to 9 inches, and adds an in-vehicle interconnection system that can implement language control, real-time navigation, remote monitoring, and vehicle wireless functions. However, these two complaint models cover them exactly. Maybe this is a breakthrough to find out the cause of the leak. After consulting relevant information, CNKI found that some netizens posted the leak points they found on the car forum of a website, which is a newly added vehicle interconnection system of about 2020 models. The netizen said that due to the impact, the 4S shop was delayed to resume work The 5-litre 4WD Deluxe and 4WD Ultimate editions have attracted attention.

As shown in the figure above, first open the co-pilot ’s glove box, find the safety box, unplug the second safety plug in the left column, and close the car screen. According to netizens testing, this method can reduce the quiescent current to nearly 0A, as high as before 1A. The second method is to remove the large central control LCD screen and unplug the intelligent connection module to solve the leakage problem. Although this method does not affect 360 image, Bluetooth and other basic functions, only the car network cannot be used, but the car quality network recommends that most owners do not try it easily. After all, unauthorized removal of accessories may affect the quality assurance of the entire car. In relevant forums and car clubs, car owners and netizens have also proposed solutions to problems, such as changing lines and installing intelligent module switches. Of course, these methods are even more undesirable. Once the route is changed without permission, all consequences will be borne by the owner according to the relevant provisions of the vehicle user manual. At present, most of the 2020 models in the complaints have been purchased within less than three months. Once they are regarded as insurance by manufacturers and 4S stores, they will cause more trouble for later vehicles. At present, with the improvement of the epidemic situation in China, cars and 4S stores will resume business one after another. It is recommended that the majority of Toda cars should be patient and rational, and protect their rights and interests in accordance with the relevant provisions of the "Three Guarantees for Automobiles". If shopping malls in some areas of 4S cannot resume normal work in a short period of time, simple emergency measures can be appropriately selected to prevent leakage problems from affecting daily vehicles, but this is not a long-term solution. Judging from the information currently available, the total leakage problem or product defect has been formed in 2020, and there is reason for auto companies to study and solve the problem as soon as possible to completely eliminate hidden dangers. After all, leaks can cause the battery to lose power, which can make the vehicle unusable. During the epidemic period, I hope that automobile companies can overcome all difficulties, shoulder their due social responsibilities and obligations, and reduce the health risks and safety hazards caused by automobile product quality problems for car owners as soon as possible.
