Logged a full 10% to 80% DC fast-charging session on my BYD Seal Performance AWD (82.5 kWh) at a 350 kW Kempower CCS2 charger after a 90-minute highway drive (battery temp at 29°C):

On-Road Impressions, Efficiency & Setup Details

• 10% to 35% SOC: Holds 148–154 kW flat.
• 35% to 55% SOC: Holds 118–126 kW.
• 55% to 80% SOC: Holds 85–92 kW.
• Total Time (10% -> 80%): 26 minutes 15 seconds (added 59.8 kWh including thermal losses).

Sharing my detailed energy consumption and charging log on the BYD Atto 3 Extended Range (60.5 kWh Blade Battery) across First 5,000 km of mixed commuter and highway driving.

1. Real-World Consumption Breakdown

• Urban / Suburban Commute (40–70 km/h, High Regen, Eco Mode): Consistently averaging 13.4 to 14.2 kWh/100km, translating to 420–440 km of real urban range per charge.
• 110 km/h Motorway Cruise (AC set to 22°C, 38 PSI tyre pressure): Consumption settles at 17.6 to 18.4 kWh/100km, giving a reliable 315–330 km highway leg with a 10% SOC buffer.

2. DC Fast Charging & 7kW AC Wallbox Notes

• On a 150 kW CCS2 charger, plugging in at 12% SOC pulls 88 kW peak up to 48% SOC, then steps down to 56 kW until 78% SOC (10% to 80% takes 33 minutes).
• Overnight 7kW AC single-phase charging from rooftop solar/off-peak grid adds ~11% SOC per hour with ~92.5% charging efficiency.
