Charging & Driving Rules

DC Sweet Spot

Charge 15-70% SOC for peak throughput (~50 kW avg)

Never Past 85%

Last 15% wastes 15-20 min on DC — adds cost for minimal range

Sport Mode Tax

25% efficiency penalty — costs ~₹100 extra per 100 km at DC rates

Free Charging

Always ask homestays/hotels for a 15A socket — saves ₹300-500

Above 100 km/h

Aero drag scales with speed² — range drops disproportionately

AC Discipline

24°C + recirculation saves 1-1.5 kWh/100km on highway
