What is the actual lifespan of BYD's lithium iron phosphate battery?
2 Answers
BYD's lithium iron phosphate battery has a theoretical lifespan of around eight years. Below is an introduction to the lifespan, advantages, and disadvantages of BYD's lithium iron phosphate battery: Battery lifespan: BYD's lithium iron phosphate battery can withstand over 2,000 charge-discharge cycles. With daily charging, it can last for more than five years. For typical household use with charging every three days, it can last around eight years. Advantages of lithium iron phosphate batteries: Lithium iron phosphate batteries offer strong safety and stability, high-temperature resistance, and environmental friendliness. They do not explode or catch fire even when short-circuited. Disadvantages of lithium iron phosphate batteries: They are relatively large in size, occupying more space in household new energy vehicles. While excelling in high-temperature resistance, lithium iron phosphate batteries perform poorly in low-temperature discharge performance.
I've been using a BYD electric car for over five years, and the battery is still in good condition. The actual lifespan is usually quite long, with lithium iron phosphate batteries being more durable than other types. BYD's Blade Battery has a design lifespan of 10 years or even longer, depending on daily usage habits. For example, I usually avoid frequent fast charging because it increases the burden on the battery. I also keep the charge level between 20% and 80% instead of charging it to 100%, which helps protect battery health. Additionally, extreme temperatures can affect lifespan, so I try to park in shaded areas during winter and summer. Generally, the battery can endure around 3,000 charge cycles. Based on a daily commute of 50 kilometers, it can last over ten years without issues. I recommend following the vehicle manual's advice and getting regular check-ups at a 4S store. When driving, maintain smooth acceleration and avoid sudden speed changes—these small habits can help extend the battery's lifespan.
