What is the service life of new energy vehicle batteries?
2 Answers
The designed lifespan of new energy vehicles is generally six years or even more than ten years. The service life of new energy vehicle batteries is closely related to the driver's daily driving habits. Frequent aggressive driving and improper charging time management will affect the battery's lifespan. Here are three aspects to consider for new energy vehicle maintenance: 1. Avoid direct sunlight: When a new energy vehicle is exposed to direct sunlight, the internal pressure of the battery increases, leading to water loss, reduced battery activity, accelerated aging of the battery plates, and a shortened battery lifespan. 2. Master the correct charging time: During normal driving, if the power meter indicates red or yellow lights, it's time to charge. Generally, the average charging time for new energy vehicle batteries is about 10 hours. Owners need to control the charging time to avoid losses caused by overcharging. If the battery temperature exceeds 65°C during charging, stop the charging process. 3. Regular inspections: If the driving range of a new energy vehicle suddenly drops significantly by more than ten kilometers in a short period during normal operation, it may indicate a problem with one of the batteries, requiring timely inspection.
I've been driving a new energy vehicle for almost three years. The battery lifespan is generally five to eight years, depending on usage habits and vehicle condition. Mine has a lithium battery design, and the manufacturer's warranty is usually eight years or until a certain mileage is reached first. When charging, it's advisable not to always use fast charging, as it causes significant battery wear, especially in summer when the car gets very hot—higher temperatures accelerate aging. I make it a habit to use slow charging once a week to help preserve the battery capacity from degrading too quickly. A friend of mine had to replace his battery in less than six years, costing several thousand yuan, likely because he frequently let the battery deep discharge. With better maintenance, it could last a couple more years, and regular cleaning of the charging port also helps. Don't forget, replacing a battery allows for recycling, which is both eco-friendly and avoids waste.
