It depends on how conveniently the chargers are located. If you have a smaller battery and can go 200km you’ll need a charging station every 190km and mountainous terrain will change those distances as well. You many end up charging sooner than needed in order to get to the next charging spot. In reality it isn’t as bad as it sounds. I travel the BC interior with my short range EV and the savings in fuel make it worthwhile to stop more often. Even when I pay the high speed charging rates, it is about 1/4 the cost of gasoline per km but takes 15% longer time to get to destination vs our gas vehicle.

Enjoy your leave. You obviously have the sense to know that you are taking it for: your wife, your child and your mental health. You will give your family a better head start. Corporate won’t notice. If they are going to fire you, they’ll do it even if you had spent the time period working double overtime instead of being on leave.
