Charging Your BYD Sealion 7 at Home in Perth
The BYD Sealion 7 was Australia's second best-selling EV in 2025, just behind the Tesla Model Y — and unlike its stablemate the Atto 3, the Sealion 7 supports three-phase AC charging at up to 11 kW. That means Perth homeowners lucky enough to have three-phase power can fully charge the Sealion 7's 82.5 kWh extended-range battery in around 8 hours. On standard single-phase 7.4 kW, it's around 12 hours — still perfectly adequate for overnight charging. Sparky Local installs home EV charging throughout Southern Perth.

Common Questions
What's the right wallbox for a BYD Sealion 7?
If your home has single-phase power (most Perth suburban homes), any good 7.4 kW Type 2 wallbox works perfectly. For solar homes, the Zappi is the clear choice. If you have three-phase power, a 22 kW-capable charger like the Fronius Wattpilot lets the Sealion 7 charge at its full 11 kW three-phase rate.
Is overnight charging on 7.4 kW enough for the Sealion 7's large battery?
For most Perth drivers, yes. The average daily drive in Perth is around 30–50 km. At 7.4 kW, you add approximately 45 km of range per hour — so a 2-hour top-up covers most daily usage. Full charges from depleted take around 12 hours overnight, which fits comfortably within a standard home charging window.
