Formula
Energy added = capacity × (endSoC − startSoC) ÷ 100; cost = energy ÷ (1 − loss%) × rate per kWh

FAQ
Full-battery range = capacity (kWh) ÷ efficiency (kWh/100km) × 100. A 60 kWh battery at 16 kWh/100km gives about 375 km. Real range varies with air-con, speed, and load.
Enter your trip distance to see the charges needed and battery % left afterwards. Keep a 10–20% buffer, as real range is usually lower than theoretical.
Charging at home on a TOU meter during Off-Peak (10pm–9am) is around 2.6 THB/unit, versus roughly 4.2 THB/unit on a normal meter. Public AC/DC stations run about 6.5–8 THB/unit, so off-peak home charging is the cheapest option.
The energy drawn from the grid is slightly higher than what reaches the battery because of conversion losses (typically 5–15% for AC). Your bill is based on grid energy, so you can adjust this figure under advanced options.
