BYD Atto 3 Charging Speed Problems – Why It’s Slower Than You Expect
⚠️ Charging Taking Longer Than It Should? Let’s Break It Down
The BYD Atto 3 supports both AC and DC charging, but many owners and reviewers have pointed out that its charging speeds are slower than most rivals—especially when using public rapid chargers.
The issue isn’t always the charger. Sometimes it’s onboard settings, battery management, or a hidden fault in the high-voltage system.
🔧 Slow Charging Symptoms We Commonly Fix:
| Problem | What We Check |
|---|---|
| ⚠️ DC charging never reaches full advertised speed | Inlet module, HV battery temp, charge controller |
| ⚠️ AC home charging taking longer than usual | Onboard charger, cable fault, fuse/circuit resistance |
| ⚠️ Charging starts but then slows dramatically | Thermal throttle, state-of-charge sensor, software bug |
| ⚠️ Charger fails to initiate session | Comms fault, earth fault, OBC firmware issues |
| ⚠️ Charging session stops randomly | Pilot signal dropout, control relay failure |
🧠 The BYD Atto 3 has a conservative battery management system. But that doesn’t mean you should accept glacial charge speeds—especially if other cars charge faster on the same unit.
