Singapore car repair guide

BYD Sealion: Charging slower than expected / charging stops halfway

If you are seeing this symptom in Singapore, use this as a pre-workshop checklist. The goal is to identify the likely root cause, avoid replacing the wrong part, and know the fair repair range before approving work.

Fair SG range
$80–$450
Red-flag quote
$1,500+
Likely fix
Charging setup check, software update, thermal/charging module scan

What this usually means

Slow or interrupted charging can be charger rating, cable limit, battery temperature, software limit, or handshake error. Confirm charger kW, cable rating, and battery temperature before diagnosing the car as faulty.

What to ask the workshop before approving repair

  • • Show the diagnostic fault codes.
  • • Show photo/video proof of the failed part.
  • • Give an itemised quote for parts and labour.
  • • Explain why cheaper common fixes were ruled out.
  • • Use/confirm: EV diagnostic scanner
  • • Use/confirm: Charging cable tester

This is not a final diagnosis. It is a money-saving checklist before you go workshop.
