How Long is the Lifespan of New Energy Vehicle Batteries?
2 Answers
The lifespan of new energy vehicle batteries is generally around 6 years. Below are relevant explanations: Potential issues: After 6 years, the frequency of malfunctions may increase. It is recommended to replace the battery promptly to address a series of problems caused by battery aging, such as significantly reduced driving range, decreased storage capacity, and slower charging. Battery maintenance: The battery's lifespan also depends on the owner's regular maintenance practices. For example, start the vehicle gently, avoid exposing the car battery to direct sunlight as high temperatures can accelerate aging, and avoid driving in low-temperature environments which can result in reduced range. When charging the battery, disconnect the power source once fully charged. Charging time should not be excessively long, and over-discharging should also be avoided.
The lifespan of new energy vehicle batteries generally lasts around eight years, with some cars even exceeding ten years, depending on how you use them. Having driven an electric car for several years, I find the battery quite durable, but don't expect it to never age. The biggest impact comes from daily charging and discharging habits—if you frequently drain the battery completely before recharging or often park in extreme heat or cold, it will degrade faster. Manufacturers typically specify 1,000 to 2,000 charge-discharge cycles, which roughly translates to 150,000 to 200,000 kilometers. I recommend regular check-ups at a 4S shop to monitor battery health and catch issues early. Also, don’t forget to check the warranty—most automakers offer 8 years or 160,000 kilometers of coverage, so you can get a free replacement if the battery fails. Overall, battery lifespan is like a smartphone battery: it diminishes over time, but proper care can extend its useful life by a few more years.
