Charging time assumes a steady average rate across the selected window. Actual charging can vary with battery level, temperature, charger and conditions. Cost uses your current rate and charging-loss setting; it excludes the monthly subscription.

05 / SUBSCRIPTION BREAK-EVEN

When does the new rate pay off?

Drive around 928 km each month to cover the S$60 subscription through the lower electricity rate.

928 km / mo≈ 207 kWh from the wall

Method: battery kWh = distance × Wh/km ÷ 1,000. Wall kWh = battery kWh ÷ (1 − charging loss). The old plan assumes no subscription and the same charging loss. Actual use varies with speed, elevation, weather and charging conditions.
