BYD New Energy Vehicle Maintenance Guide
Maintaining your BYD new energy vehicle (NEV) ensures optimal performance, longevity, and safety. Below is a comprehensive guide to routine care and best practices, tailored for BYD NEV owners.
1. Battery Maintenance
The battery is the core of your NEV. Proper care can extend its lifespan and maintain efficiency:
Avoid Extreme Charging: Keep the battery charge between 20%–80% to prevent over-discharging or overcharging. Use the original BYD charger for compatibility and safety.
Balanced Charging: Perform a full charge (100%) once a month to balance the battery cells and ensure consistency.
Temperature Management:
In hot climates, monitor the cooling system to prevent overheating.
In cold environments, park indoors when possible and precondition the battery before driving.
Regular Diagnostics: Schedule battery health checks during maintenance visits to detect degradation early.
BYD’s advanced Blade Battery technology (e.g., used in models like the Han and Seal) is designed for durability, but proactive care remains essential.
2. Maintenance Schedule
Follow a structured maintenance plan based on usage and mileage:
Daily Checks:
Inspect tire pressure, brake functionality, and warning lights.
Verify cable connections for charging ports.
Minor Maintenance (Every 6 months/5,000–10,000 km):
Replace cabin air filters.
Inspect electrical systems (e.g., motors, inverters) and coolant levels.
Major Maintenance (Every 2–3 years/40,000–60,000 km):
Replace brake fluid and transmission oil (for plug-in hybrids like the Qin PLUS DM-i).
Check suspension, steering, and high-voltage systems.
For hybrid models (e.g., Qin PLUS DM-i), additional engine-related tasks (e.g., oil changes) apply every 7,500 km.
3. Key Components to Inspect
Focus on systems unique to NEVs:
Electric Motor and Inverter: Ensure no abnormal noises or vibrations. Dust and moisture can affect performance.
Braking System: Regenerative braking reduces wear, but inspect brake pads and discs periodically.
Tires: Rotate tires every 20,000 km to ensure even wear, especially given the heavier weight of NEVs.
4. Driving Habits for Efficiency
Smooth Acceleration/Braking: Avoid sudden starts/stops to reduce strain on the motor and battery.
Utilize Regenerative Braking: Maximize energy recovery in urban driving.
Preconditioning: Use the app to heat/cool the cabin while plugged in, preserving battery range.
5. Service Provider Selection
Authorized BYD Service Centers: These use genuine parts and adhere to warranty requirements. For example, BYD offers free first maintenance at 3,500 km or 6 months.
Third-Party Workshops: If used, ensure they are certified for NEVs to avoid voiding warranties.
6. Environmental Adaptations
High-Temperature Areas: Shorten maintenance intervals and prioritize cooling system checks.
Frequent Long Trips: Inspect tires and brakes more often after extended drives.
7. Warranty and Cost-Saving Tips
Leverage Service Packages: BYD often provides discounted maintenance bundles for multi-year plans.
Keep Records: Document all services to validate warranty claims and resale value.
Conclusion
BYD’s NEVs, such as the Seal, Han, and Denza N9, combine cutting-edge technology (e.g., e³ platform, DiSus-A suspension) with robust engineering. By following this guide, you can maximize your vehicle’s performance while contributing to sustainable mobility. For model-specific advice, consult your BYD manual or service center.
Note: Always prioritize BYD’s official recommendations for your specific model and region.
