The useful comparison is between energy needed for the next day and energy that can be delivered inside the tariff window. How can that be estimated without assuming every night starts with an empty battery?
EVVerity explains
For an illustrative 60 km day at 18 kWh/100 km, driving uses 10.8 kWh. If charging efficiency were 90%, replacing it would require about 12 kWh from the supply. Four hours at a sustained 3 kW would just match that assumption; colder days or a shorter effective window would need more margin.
