On April 25, it was reported that for the quality of domestic electric vehicles, you should rest assured that there is no need to be too obsessed with the so-called joint venture brand.
Recently, the U.S. Department of Energy's Office of Vehicle Technology launched a study titled "New Study: How Long Do EV Batteries Last?", which shows that EV battery failure rates have dropped dramatically.
According to the data, the reliability of EV batteries has come a long way in the last decade, especially in recent years.
The study looked at battery data from about 15,000 rechargeable cars between 2011 and 2023. The results showed that the battery replacement rate (due to failure rather than recall) was much higher in early (2011-2015) than in recent years (2016-2023).
The report states that most failures are resolved within the manufacturer's warranty period. The improvement in battery reliability is due to more mature technologies such as active liquid battery cooling systems, new battery thermal management strategies, and newer battery chemistries.
In addition to this, stricter quality control also plays an important role.
