AutoBeta(AutoBeta.net)09/23 Report--

According to Mr. Yu, the owner of the Euler car in Hangzhou, "after the recall in July, the manufacturer did not give us a recognized solution, that is, a door-to-door mandatory upgrade, after which the mileage will be shortened." then the recharging time will also increase.

According to the announcement of the State Administration of Market Supervision and Administration, Great Wall Motor Co., Ltd. filed a recall plan with the State Administration of Market Supervision and Administration, and decided to recall a total of 16216 Great Wall Euler IQ electric vehicles manufactured between July 7, 2018 and October 30, 2019, starting from July 16, 20121. According to the announcement, the reason for the Euler IQ recall is that the consistency of some power batteries carried by the vehicle is different from that of the BMS software control strategy. After long-term continuous and frequent fast charging, the performance of the battery decreases, and in extreme cases, the power battery may be out of control and there is a hidden danger of safety. In view of the above defects, Great Wall Motor will test the power battery of the vehicle in the recall area free of charge, and write the control strategy software adapted to the working condition scene, and replace the battery module if necessary, in order to eliminate the hidden danger.

However, a number of car owners reported that at present, 4S stores only carry out "brushing" upgrades for recalled vehicles, and this upgrade is actually a program that limits the charging power of vehicles, and the battery module has not been replaced. From the point of view of Mr. Euler and many other Euler owners, the upgrade of the system carried out by the manufacturer after the recall is only to cope with, and the so-called upgrade should be a "downgrade", because the range and charging power of the vehicle after the upgrade have been reduced, which does not solve the fundamental problem. For manufacturers of this recall solution, many car owners do not recognize, require manufacturers to come up with an effective solution, or replace the battery.

A lawyer said that if there is a risk of charging spontaneous combustion of automobile products, manufacturers should recall the cars to eliminate related defects and hidden dangers. Judging from this incident, manufacturers upgrade the car software at the cost of battery life and charging power, which is not the best solution. From the point of view of manufacturers, manufacturers should use the optimal way to remove the hidden danger of spontaneous combustion and at least respect the rights and interests of consumers to deal with the recall of products. From the consumer's point of view, you can lodge a complaint to the market supervision and management department, and you can also file a complaint to the Consumer Association, which is involved in the mediation investigation.

In addition, car owners report that charging pile operators restrict Euler charging, and it is not the only one. As for the reason for restricting charging, it may have something to do with Euler's fire. In June this year, a live video posted on the Internet showed that the entire vehicle of an Euler model was quickly surrounded by a raging fire and billowed with smoke, causing a large area of the vehicle involved to overfire and damage and basically scrapped. The customer service staff of the charging station said that the reason for the spontaneous combustion of the Euler iQ is that the power of the charging pile does not match that of the vehicle, which can easily lead to battery burning, so owners of the Euler iQ are advised not to charge quickly or to choose low-power DC piles.
