How Long is the BYD Battery Warranty?
1 Answers
BYD's new energy battery pack warranty is 8 years or 150,000 kilometers. The vehicle warranty is 6 years or 150,000 kilometers. Additionally, the battery cells come with a lifetime warranty service, which is generally higher than other electric vehicle brands in the same class. The battery packs of new energy vehicles have a limited lifespan. BYD's new energy vehicles use self-produced lithium iron phosphate (LFP) batteries and ternary lithium batteries. The specific advantages and disadvantages are as follows: Ternary Lithium Battery Advantages: Ternary lithium-ion batteries have high energy density, long cycle life, and are not afraid of low temperatures. Disadvantages: Insufficient stability at high temperatures. Application: Pure electric vehicles with high range requirements. It is the mainstream direction and suitable for northern climates, as the battery remains more stable in low temperatures. Lithium Iron Phosphate (LFP) Battery Advantages: Lithium iron phosphate batteries have excellent thermal stability, are safe, cost-effective, and have a long lifespan. Disadvantages: Low energy density and poor performance in low temperatures. Application: The internal chemical composition of these batteries only begins to decompose at temperatures between 500-600°C. They do not catch fire or explode under puncture, short circuit, or high-temperature conditions and have a long service life. However, the vehicle range is generally limited, and charging efficiency is low when temperatures drop below -5°C, making them unsuitable for winter charging needs in northern regions. In the battery sector, BYD has 100% independent research, development, design, and production capabilities. Currently, BYD's battery products cover consumer 3C batteries, power batteries (LFP and ternary batteries), solar batteries, and energy storage batteries, forming a complete battery industry chain. BYD is also the world's largest LFP battery manufacturer in terms of production capacity.
