AutoBeta(AutoBeta.net)03/14 Report--

Recently, the automobile industry pays attention to the understanding from the black cat complaint platform that since March, many car owners have complained that the first batch of Xiaopeng P7 electric cars, the new force of car building, are suspected to be "power-locked" for no reason. The first batch of owners of Xiaopeng P7 complained that their cars experienced a significant drop in mileage after an OTA (car remote upgrade) at the end of last year, so these owners suspected that Xiaopeng had "locked up" the vehicles through OTA.

A car owner said: "Xiaopeng car background lock power, 80-degree version of Xiaopeng p7, can charge up to 70 degrees, while 70-degree version, can charge 71 degrees, 4s test communication results for background behavior, unable to intervene, this phenomenon occurs after February 2021, Xiaopeng car locks power through ota." Another owner said: "the 80-degree battery of Xiaopeng P7 electric vehicle can only use about 70 degrees, and the manufacturer executes it through the software OTA without notice, and the mileage is seriously falsely marked. 568 says it can only drive 400km."

In response to the suspected "power lock" situation encountered by several Xiaopeng P7 models, Xiaopeng's official customer service said: if there is any doubt about the battery capacity, car owners can go to the store for free testing, according to the Financial Associated Press. However, some car owners said that he and a number of car friends found the problem a few months ago and began to contact Xiaopeng to deal with it. Xiaopeng and sales stores have repeatedly stressed that there is no "power lock". But when the car owner asked the store to do battery testing, the store said there was no relevant equipment. In addition, the relevant person in charge of Xiaopeng Automobile responded to Caijing Automobile today, saying: "with regard to the speculation that Xiaopeng's car is locked up recently, some car owners and the media calculate the capacity of the battery based on the amount of electricity charged at the charging station. It is speculated that there is Xiaopeng car" power-locking "behavior, which is not consistent with the facts. The charging of the vehicle in daily use is not the complete charge and discharge behavior in the test environment. In general, even if the battery shows a long range of 0KM, the battery will still store a little electricity, and the change of vehicle charge is also related to the ambient temperature. At the same time, with the increase of vehicle service life and mileage, the battery will decay, resulting in a reduction in charge, which is also the physical characteristics of the battery. The attenuation degree of the battery individual needs to be tested by professional equipment and methods. Customer experience is the top priority of Xiaopeng Automobile. Xiaopeng Automobile will invite customers who need to go back to the store to conduct a comprehensive inspection of the vehicle and completely dispel customers' doubts. "

"locking power" refers to locking the power of the battery, that is, by upgrading and rewriting the battery management system of new energy vehicles, locking the battery power system and chip window, and redefining the voltage range of the battery, in order to limit the upper limit of battery charging and power consumption, in short, the mileage of the vehicle has been shortened. "locking electricity" can protect the safety of vehicle driving to a certain extent, reduce the calorific value of the battery by reducing the voltage and current, and avoid spontaneous combustion in the process of driving, but at the same time, due to the reduction of battery capacity, therefore, the mileage of the vehicle is also greatly reduced. In fact, Xiaopeng is not the first car to be exposed as a "power lock". It was Tesla who was exposed earlier. In 2019, Tesla provided software patches that "can prolong battery life" for his Model S and Model X models through OTA upgrade software, but after the OTA upgrade, some car owners reported a loss of 8 kWh of usable electricity, a reduction in driving mileage, and so on. Tesla said it was a normal loss. A similar phenomenon occurs in the United States and Norway. After that, including Guangzhou Automotive Aion S, Guangfeng iA5, Weima Automobile and so on, have also been exposed "power lock" problems.

Data show that Xiaopeng P7 is the second product of Xiaopeng, and it is also the best-selling of Xiaopeng's three models. Xiaopeng P7 was launched in April 2020 and officially delivered in June 2020. the price range is between 22.42 and 409900. Relevant data show that Xiaopeng delivered a total of 98155 new cars in 2021, which is the largest number of new car-building forces in China. From January to February this year, Xiaopeng delivered a total of 19417 new cars, including 10244 Xiaopeng P7 models.
