Recently, 10 Great Wall Euler IQ owners in Luzhai County told the South China Morning Post reporter that in July 2021, after their vehicles were recalled and upgraded by the manufacturer, the vehicle charging time increased from the original 1 hour and 40 minutes to more than 3 hours, and the mileage was also reduced by more than 100 kilometers compared with before the upgrade. On December 30 of the same year, Liuzhou Hualiu Automobile Sales Service Co., Ltd., a 4S shop that sold cars, responded that the recall vehicle upgrade was carried out according to the manufacturer's instructions, with the purpose of optimizing the battery pack software, improving the stability of the battery under the high-intensity operation of fast charging, and regulating the fast charging current and charging voltage, so it will affect the charging time and mileage of the vehicle.

Owner: The mileage of the subsequent vehicle upgrade is reduced
Mr. Wang is a taxi driver in Luzhai County. In March 2019, he signed a contract with Luzhai Yuntong Taxi Co., Ltd. to contract the 8-year operation right of a Great Wall Euler IQ car just purchased by the company.
"Although the vehicle was purchased by the company, it was actually for personal use." Mr. Wang told reporters that the purchase price of the vehicle at that time was 95,800 yuan, and then added 10,000 yuan, and renewed an insurance for the vehicle's battery, motor, etc., and the insurance period was 3 years and 300,000 kilometers.
In July 2021, Mr. Wang received calls from Great Wall Motor manufacturers and 4S stores informing him that he needed to recall vehicles and upgrade software. But after the upgrade, Mr. Wang found that his car charging speed was much slower than before, "before the full charge was only 1 hour and 40 minutes, now it takes more than 3 hours." "Not only has the charging speed of the car become slower, but the endurance has also shrunk seriously, "Before it could run about 350 kilometers, now it can only run about 250 kilometers." ”
Progress: The problem with replacing the battery with a new one still exists
After Mr. Wang reported to the 4S shop where he bought the car, the 4S shop replaced his car with a new battery on August 14 of the same year. On September 30 of the same year, after Mr. Wang got the car, he found that the problem still existed, and the charging speed and endurance of the car did not change.
It is understood that there are 9 people who contract vehicle operations at the same time as Mr. Wang. The 9 owners all use Great Wall Euler IQ cars, which are purchased by Luzhai Yuntong Taxi Co., Ltd. to Liuzhou Hualiu Automobile Sales Service Co., Ltd. After the 9 car owners returned the vehicles to the 4S shop for software upgrades, they all experienced a shrinkage of mileage and an increase in charging time.
After these owners successively reported the situation to Liuzhou Hualiu Automobile Sales Service Co., Ltd., the company's technical personnel tested that there was no problem with the batteries of Mr. Wang and other people's vehicles. For the response of the 4S store, Mr. Wang and others did not approve, "The vehicles are all in these situations after the upgrade, what is going on?" ”
4S Shop: Recall vehicle upgrade is a manufacturer requirement
On December 30, 2021, the reporter came to Liuzhou Hualiu Automobile Sales Service Co., Ltd. to understand the matter. Ms. Ning, the company's after-sales director, said that the recall of vehicle upgrades is a manufacturer's request.
▲On December 30, 2021, Mr. Wang and others exchanged views with the relevant personnel of the 4S shop on vehicle-related issues.
The reporter inquired about the relevant information and learned that in July 2021, Great Wall Motor Co., Ltd. decided to recall the Great Wall Euler IQ electric vehicles produced between July 7, 2018 and October 30, 2019, a total of 16,216 vehicles. The reason for the recall of the vehicle is that the battery has a safety hazard in the long-term continuous and frequent fast charging state. To this end, Great Wall Motor Co., Ltd. tests the power battery of the vehicle within the scope of the recall free of charge, and brushes the control strategy software adapted to the working conditions, and replaces the battery module if necessary to eliminate the safety hazard.
For why the upgrade will increase the charging time and reduce the endurance, Ms. Ning said that the upgrade is to optimize the vehicle battery pack software, improve the stability of the battery under the high-intensity operation of fast charging, and have certain regulations in terms of fast charging current and voltage, which will affect the charging time and endurance of the vehicle.
"We can only feedback the owner's appeal with the manufacturer, and the manufacturer has also given us some guidance." Ms. Ning told reporters that the vehicles of Mr. Wang and others are operating vehicles, which have traveled more than 200,000 kilometers in the past 3 years, and the performance of the car has a certain loss, "Although we helped replace the new battery, the other accessories of the vehicle are still old, so the endurance cannot reach the original standard." Ms. Ning said that the current cold weather has also had a certain impact on the vehicle battery, which affects the endurance.
▲ Mr. Wang and others drove their cars to the 4S shop to defend their rights.
An industry insider who did not want to be named told reporters that the battery used by the Great Wall Euler IQ electric vehicle uses an air-cooled passive cooling system, which has a safety hazard, and there have been many spontaneous combustions of Euler cars in China before, so the manufacturer should recall the vehicle for upgrading. This upgrade actually limits the charging speed of the vehicle and reduces the amount of charging, resulting in an increase in the charging time of the vehicle and a shrinking endurance.
In the afternoon of the same day, the reporter called the official customer service telephone number of Euler on this matter, and a customer service staff recorded the reporter's appeal and said that he would give a reply in two working days. As of press time on January 4, Euler had not responded.
