What is BYD's battery degradation standard for battery replacement?

[SimonAnn]

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).
