What is BYD's battery degradation standard for battery replacement?
2 Answers
BYD's battery degradation standard for battery replacement is as follows: 1. 1 to 10 years: The degradation rates are 8%, 4%, 2%, 2%, 2%, 1.5%, 1.5%, 1.5%, 1.5%, 1.5% respectively. 2. Over three years: The battery degradation level has already affected normal usage. 3. Grading: When the current battery capacity is lower than the nominal capacity, it is considered degraded. When the capacity falls below 20%, it is deemed severe battery degradation. There are many reasons for battery degradation, mainly including: 1. Quality issues: Poor battery quality itself. 2. Poor charger: Using inferior chargers. 3. Working environment: Operating in high or low-temperature environments for extended periods. 4. Overcharging and discharging: Using the battery until the remaining charge is below 3%. Circuits have protection, but it occasionally happens. 5. Radiation: Long-term use of the battery in areas with strong electromagnetic radiation (which can interfere with the conductivity of metals inside the battery).
As an experienced EV owner, I find BYD's battery degradation replacement policy quite user-friendly. During the warranty period (typically 8 years or 160,000 km), you can apply for a free battery replacement when the capacity drops below 70% of its original value. Specifically, if your range decreases from 400 km to around 280 km, you qualify. I recommend new owners regularly monitor battery health via the BYD app and adopt good habits like avoiding deep discharges or high-temperature charging to significantly slow degradation. If issues are detected, BYD dealerships handle replacements efficiently, usually completing the process within three days. This is particularly valuable for long-distance drivers since the battery is the EV's heart - proper maintenance boosts both performance and lifespan. Overall, this standard makes ownership more worry-free and safer.
