How Many Years Can an Electric Vehicle Battery Last?
2 Answers
Electric vehicle batteries can last for more than 8 years if they are lithium titanate; around 5 years for lithium iron phosphate; and generally only about 3 years for ternary lithium batteries. Here are the specific maintenance tips for electric vehicle batteries: 1. Avoid Hard Acceleration: Aggressively pressing the accelerator during startup, carrying passengers, or climbing slopes causes the battery to discharge with high current, which can easily lead to lead sulfate crystallization. This damages the physical properties of the battery plates, resulting in a sudden drop in speed and performance. 2. Prevent Exposure to Extreme Heat or Cold: If the vehicle is parked under intense sunlight for a long time, the high temperature will increase internal battery pressure, leading to water loss and reduced battery activity, accelerating plate aging. If parked in extremely cold environments for extended periods, the battery's range will drop sharply, and its performance will be adversely affected. 3. Master the Correct Charging Time: Pay attention to the duration and degree of charging to avoid undercharging or over-discharging. Generally, battery charging takes about 8-10 hours. Be especially cautious not to charge for too long, as overcharging can shorten the battery's lifespan.
To be honest, I've been driving electric vehicles for many years, and battery lifespan typically ranges from 8 to 15 years, depending on the vehicle type and usage habits. Lithium-ion batteries are the most common and are greatly affected by temperature—for example, parking in direct sunlight during summer can accelerate aging. Charging methods are also crucial: I make it a habit to keep the charge between 20% and 80%, avoiding deep discharges or charging to 100%, as this helps slow degradation. Manufacturer warranties usually cover 8 years or 160,000 kilometers, addressing capacity drops below 70%. For daily use, I recommend slow charging once a week and minimizing fast charging; in extreme weather, park in a garage for protection. Overall, with proper maintenance, EV batteries can outlast traditional combustion engines, saving money and being more eco-friendly.
