How much does it cost to charge a BYD at home?

Charging at home is where EVs win on cost. A BYD Atto 3 carries roughly a 60 kWh battery, and what you pay to fill it depends entirely on your electricity tariff and when you charge.

The simple maths

Cost to charge = battery size (kWh) x your rate ($/kWh). On a typical flat residential rate of around $0.35/kWh, a full 0-100% charge is about $23. That covers roughly 400 km of real-world range, or under $6 per 100 km.

Shift to off-peak and it gets cheaper

Most distributors offer time-of-use or dedicated EV tariffs. Charging overnight on off-peak or EV plans (often $0.08 to $0.12/kWh) drops a full charge to roughly $5 to $7. Compare that with a public DC fast charger or Supercharger at around $0.69/kWh, which is closer to $40 for the same energy. Home charging is where the savings live.

• Set a charge schedule in the Voltara app to start after your off-peak window begins.
• Pair with rooftop solar and a charge-on-solar mode and the marginal cost can approach zero.
• Compare against petrol: 400 km in a small SUV is roughly 30 L, or about $50 at the pump.

What changes the number

Charger speed does not change the cost, only the time. A 7 kW wall charger fills the Atto 3 in around 8-9 hours overnight, which is plenty for daily driving. Battery degradation and very cold mornings have a small effect, but for budgeting, battery size times your rate is all you need.
