for the tesla model 3, there are two battery options, you can either opt the 50kwH or the extra range 75kwh battery pack
now the cost of juicing (running) it
lets say i have a 50kwh tesla .
1 kwh is equal to 1 unit of electricity , so 50 units would be needed to charge the battery completely, now in punjab, consumer electricity tarriff in home is around 12 rs / unit ( rounded ) . thats ( 12 x 50) , 600 PKR to fully charge your tesla in your home ( a slow process taking 6-7 hours since home voltage and current is low, )
now tesla advertised range for 50kwh model is 350 km on full charge, of course thats a sales number, ill assume 250 -275 km in real world conditions ( family on board, braking , accelarating etc ) .
so ,
600 ruppes per full charge in punjab= 260 km EV range
that around 2.3PKR per km running cost ,
