BYD Won't Charge: How to Fix Charging Problems at Home and in Public

Is the Problem at Home or at a Public Charger?

Start here — the cause and fix often differs by charging type.

• Home (3-pin or wallbox): Usually a cable, wallbox, or scheduling issue
• Public DC rapid charger: Usually a charger hardware or compatibility issue
• All charging types: May indicate a car-side fault

Home Charging Problems

The Car Won’t Start Charging When Plugged In

1. Check the cable connection

• Unplug from both ends (car and charger) and reconnect firmly
• Listen for the click of the car-side lock engaging
• Try a different cable if available

2. Check for scheduled charging

• BYD EVs support scheduled charging (charges at off-peak hours)
• If scheduled charging is active, the car will NOT start immediately
• To override: In the car’s infotainment, go to Charging → Scheduled Charging and disable it, or change the start time

3. Check the wallbox

• Look for error lights on the wallbox (usually a flashing or red status light)
• Try resetting the wallbox by switching off its circuit breaker for 30 seconds, then back on
• Some smart wallboxes need to be in “ready” state — check the wallbox app

4. Check your home fuse/circuit breaker

• A dedicated EV circuit should be on its own breaker
• If the breaker has tripped, reset it. If it trips again, call an electrician — there may be an overload or wiring issue

5. Try the 3-pin cable

• Use the granny cable (3-pin to Type 2) that came with the car
• Plug directly into a standard 13A socket
• If this works, the wallbox is likely the fault

Charging Starts but Then Stops

1. Check for overheating

• Charging slows or stops in very high ambient temperatures to protect the battery
• In hot weather, park in shade and try again. Pre-conditioning on a cooler day may help.

2. Check charge limit settings

• If you’ve set an 80% charge limit in the car’s settings, charging will stop at 80%
• BYD LFP models can (and should) charge to 100% — remove any charge limit

3. Check the wallbox for faults

• Smart wallboxes sometimes drop the session due to app/server errors
• Try a manual (non-smart) session by disabling scheduling in the wallbox app

4. Cable temperature

• Very cold weather can cause some cables to stop charging to protect the connectors
• Move the car to a warmer location or let ambient temperatures rise before retrying

Public DC Rapid Charging Problems

Charger Not Communicating with Car

1. Try a different charger

• If one DC charger fails, try another on the same site (or a different network)
• Check Zap-Map (UK) or PlugShare (global) for real-time charger fault reports

2. Check CCS connector and car socket

• Inspect the CCS (Combined Charging System) connector — look for bent pins or debris
• Inspect the car’s DC charging port for visible damage or contamination

3. Restart the charging session

• Unplug from the car completely
• Wait 60 seconds
• Re-initiate the session on the charger and reconnect

4. Check the car’s battery temperature

• DC fast charging requires the battery to be within a temperature range (~10–45°C)
• After a long motorway drive, the battery may be too hot for peak DC charging
• Wait 10–15 minutes for the battery to cool
• In very cold weather, the battery may need pre-conditioning before DC charging

5. Charger compatibility

• BYD EVs use CCS2 (European standard). Ensure the charger is CCS compatible.
• Tesla Superchargers require the charger to be CCS-compatible (newer V3 sites in UK/Europe are)
• Some older chargers have compatibility issues with specific BYD models — check the BYD compatibility list

Charging Speed Much Lower Than Expected

This is often normal: BYD’s (and all EVs’) charging speed is highest between 10–50% charge. Speed naturally reduces as the battery fills to protect cell longevity. A 10–80% charge is the sweet spot for speed.

Error Messages on the BYD Screen

When to Contact Your BYD Dealer

Contact your dealer if:

• The car shows a “Battery fault” or persistent “OBC fault” error
• Charging fails consistently across multiple chargers and cables
• The problem developed suddenly after normal operation (may indicate a software or hardware fault)
• Charging worked previously on a home setup and nothing has changed

These may be warranty-covered faults. Document when the fault started and any error codes shown.
