BYD Sealion 7 versions and prices

Guide prices checked October 2026 and may already include the Electric Car Grant. Real-world range is EV Database's typical estimate; the official WLTP figure is higher. Always confirm the price with the seller.

Charging

The BYD Sealion 7 can rapid charge at up to 150 kW. That peak only lasts part of a session: averaged from 10% to 80%, it is about 115 kW, about 32 minutes on a fast enough charger.

At home it accepts up to 11 kW on AC. On a typical 7 kW wallbox, a full charge from empty takes roughly 12 hours; most top-ups take far less. Its CCS plug is on the right side, rear. See charging times, smart EV tariffs and chargers near me.

Running costs

At 10,000 miles a year, charging 80% at home on a smart tariff at 7.6p per kWh and 20% on rapid chargers at 79p, the BYD Sealion 7 82.5 kWh RWD would use about 3,438 kWh and cost about £752 a year to charge (7.5p a mile).
