How Often Should the Battery of a New Energy Vehicle Be Replaced?
2 Answers
With reasonable use, the battery of a new energy vehicle can last for 8 years, after which it needs to be replaced. Here is some relevant information: The lifespan of a new energy vehicle battery is not a fixed value; different battery models have different service lives. Precautions for new energy vehicles: 1. Before using the vehicle daily, check the battery level and the vehicle's performance, such as braking performance, and ensure that common configurations are functioning properly. Only proceed with driving when no faults are detected. 2. If the charging part of the vehicle requires repair or fuse replacement, unplug the power cord first. Never perform maintenance while charging, as it poses safety risks and may lead to more significant accidents, causing unnecessary losses.
I've been driving a new energy vehicle for almost 6 years, and the battery is still in good condition. Generally speaking, this type of battery can last 8 to 10 years, and most official warranties cover this period, like my BYD which is guaranteed for 8 years or 150,000 kilometers. The key to replacement timing lies in daily usage: if you frequently use fast charging or park in high summer temperatures, the battery degrades faster and may need replacement in 6 or 7 years; with slow charging and parking in shaded areas, it might last up to 12 years. My neighbor's Tesla battery retained only 70% of its range after 9 years and cost 30,000 to replace. I recommend paying attention to warranty terms when buying a car, maintaining good daily habits, and not waiting until it completely fails to act, as it affects driving safety and costs money. Regular checks on the driving range are also crucial.
