Common EV Questions in Sri Lanka

In Sri Lanka conditions — AC on, mixed city and highway driving — the Nissan Leaf 40kWh typically achieves 170–220km per charge. The official WLTP rating of 270km is measured in ideal European conditions without AC. Colombo traffic with AC can reduce this to around 160–180km. Hilly routes to Kandy or Nuwara Eliya will reduce range further, especially on the ascent.

A standard 13A home socket delivers approximately 1.8kW to an EV. For a 40kWh battery, a full charge from empty takes around 22 hours. This means overnight charging only replenishes about 8–9 hours × 1.8kW = ~14kWh, which is roughly 70–80km of range. For most daily commuters this is sufficient. A 7kW wallbox charger reduces a full charge to around 6 hours.

A driver doing 1,500km/month in a 15km/L petrol car at Rs. 320/litre spends approximately Rs. 32,000/month on fuel. The same distance in an EV at 18kWh/100km and Rs. 35/kWh costs approximately Rs. 9,450/month — a saving of around Rs. 22,000/month. At this rate, the fuel savings alone amount to over Rs. 260,000 per year. Use our calculator for your specific numbers.
