The moon abroad is rounder than the moon at home, and this bias is also placed in the automotive industry. In the automotive industry, there is a chain of contempt, the Japanese and German systems are greater than the United States, and the United States is larger than the Korean and French systems, and the natural domestic cars that rank last are domestic cars. Domestic cars are not only unpopular, but even in some specific things, foreign brands do, the Chinese people can understand, and in exchange for domestic brands, it will be submerged in the "spit stars" of the Chinese people.
During this time, the new domestic car-making brand WM Motors was attacked by everyone because of the "power locking" incident. Locks the battery, as the name suggests, limits the battery level. A common approach for car companies is to readjust the voltage range of the battery through OTA upgrades, limiting the amount of battery charge and power consumption. Doing so will lead to a phenomenon in which the mileage shrinks, which affects the owner's daily experience.
In fact, locking the power is not all bad, it is also beneficial. Locking the power can avoid overcharging and over-discharging the battery, which can maximize the protection of the battery and thus extend the battery life.
In addition, power locking is not unique to WM Motors, which is a common phenomenon in the new energy automobile industry. In 2019, Tesla upgraded through OTA to lock part of the power, and the battery capacity and mileage also attenuated.
In 2020, SAIC Roewe ERX5 owners feedback that the 48-degree battery can only be charged to 33 degrees at most. Therefore, many people speculate that saic motor Roewe ERX5 may have been locked.
In 2021, GAC Toyota iA5 was also exposed as a "locked electricity." Some car owners reported that after the OTA upgrade, the battery capacity of the car was reduced by nearly 10kWh, and the actual cruising range was reduced by nearly 100 kilometers.
From 2019 to 2021, the phenomenon of power locking occurs frequently. Obviously, power locking is an industry phenomenon. In addition, according to relevant information, WM Motors has also relaxed the restrictions on locking electricity, and the mileage has also returned to normal levels. Therefore, I hope that everyone can understand more about domestic cars.
