BYD has been in use for 3.6 lakh!! What maintenance is required?
BYD Dolphin, which has passed through 360,000 kilometers in just two years. The car owner focuses on 100% DC charging, never charging AC. This summarizes the key points and maintenance scripts as follows:
1.Battery health (SOH) after 360,000 km
Check results: The battery has a remaining capacity of 86.85% or has deteriorated to only about 13%.
Charging behavior: Car owners charge DC (Fast Charge) every day, and never charge AC once.
Conclusion: BYD's Blade Battery is very durable. Even charging DC alone degenerates by an average of only about 3% per 100,000 kilometers. It is predicted that it may be used up to 900,000 km before SOH is below 70%. [28: 41]
2. Air Conditioning
Because BYD uses an air fluid system to directly heat the batteries, the air conditioning system is very important.
Radiator Panel Wash: Dust and sand debris were found clogged densely, causing the fan to work hard and consume up to 3,300 watts of fire.
Kom Air Oil Flushing: Despite running for 3 lakh kilos, the sucked-out Kom Air Oil is still relatively clear (which is considered unusual for this size of distance). It is expected that the cooling system still works well.

3. Small Ball Battery Replacement (12V) [13: 25]
Change from original lead-acid battery to Lithium battery (LiFePO4) * Advantage: Much lighter weight (reduce from 11kg to about 3-4kg) and can monitor battery status through mobile applications at any time.
4. Summary of other costs and maintenance
Suspension: In the Varanty stage (160,000 km), the steering wheel and left front shock are claimed. After the Varanty run out, there is a steering rack change (about 10,000 early) and 4 early shock absorbers.
Economy: The original owner used a fuel car to pay more than 1,000 baht per day. When switching to an EV, the electricity cost is less than 500 baht per day. Save money and pay back the car cost. [31: 05]
Conclusion: This video helps reassure MTR users that the "EV car is very durable." If the cooling system is maintained and the scheduled check is maintained, even with a heavy DC charge, the battery does not deteriorate as quickly as many people worry.
