What is the battery degradation situation of BYD?
2 Answers
Nowadays, power battery technology is already very mature, and the degradation under normal usage is actually quite low. As long as you follow the instruction manual, the natural degradation of the battery remains within controllable limits, and it can almost last until the vehicle is scrapped. Here is some relevant information: 1. Reduced battery activity in low temperatures: Research data shows that at 0 degrees Celsius, the capacity of a lithium iron phosphate power battery is only 88% of its capacity at 25 degrees Celsius, a 12% decrease. The reason is that power batteries are mostly lithium-ion batteries, and the activity of lithium ions decreases in low temperatures—the lower the temperature, the lower the activity. 2. Power consumption of heating air conditioning: Electric vehicles rely on power batteries for operation. Apart from controllable degradation and reduced activity, the power consumption of heating air conditioning can be considered the biggest culprit in reducing the range of electric vehicles.
I've been driving a BYD electric vehicle for several years, and battery degradation is quite common. When it was new, a single charge could cover 400 kilometers, but now it's down to around 360, a drop of about 10%. This degradation mainly accumulates over time—the longer you drive, the more the battery capacity naturally decreases. BYD uses lithium iron phosphate batteries, which are relatively durable, but they can't completely avoid degradation. I maintain good charging habits, rarely letting the battery fully deplete before recharging, and I only use the original charger. Extreme temperatures have a greater impact; prolonged exposure to summer heat accelerates battery aging. I'd advise new owners to pay attention to maintenance. BYD offers an 8-year or 150,000-kilometer warranty, so if the degradation is too rapid, you can get a free inspection and repair. In short, degradation is normal, but proper care can extend the battery's lifespan.
