PRACTICAL GUIDE
How long does a BYD take to charge?
For home charging, estimate the energy you need to add, then divide by the power the car will actually receive. For rapid charging, use your exact model’s published charging window and allow for power to fall as the battery fills.
- Subtract the starting percentage from your target.
- Multiply the correct usable battery energy in kWh by the percentage-point gain divided by 100. This estimates the energy to add.
- For a steady AC session, divide energy to add in kWh by the available kW for a rough number of hours.
- Allow for losses and changes in actual power.
- For DC, compare the published percentage window for the exact variant, such as 10–80%, rather than dividing a whole battery by peak power.
What to expect
You have an approximate number of hours for the chosen percentage gain at the actual AC power. For example, adding 30 kWh at a steady 7 kW takes about 4.3 hours before losses; this is an arithmetic example, not a BYD model specification.
If that did not work
If actual charging repeatedly takes much longer under comparable conditions, check the operator or wallbox’s delivered-power record first. Give BYD recurring vehicle warnings or a fault that follows the car across suitable points.
Why a 7 kW label is not a fixed rate
The car’s AC limit, supply and charger settings can be lower. Temperature, conditioning, sharing and the slowing rate near full affect the session. The Charging Lab can help plan with your own efficiency and prices.
