12 kWh is the battery of base model which has 130 km of range. The one dewan launched has 18.5 kWh battery with 200 km of range. There's 300 km range model as well which I heard dewan will launch later.
I was of the same view as yours that the vehicle is price higher in Pakistan but after checking the price in Thailand, it's slightly high. Not that much.
Price of 200 km range model in Thailand is
500,000 baht ~ PKR 3,772,966
As far as my knowledge is, car prices in Thailand are usually less than Pakistan.
