I'm not sure if I will get a level 2 charger at this time. I will be charging at work for free so more likely I'll just charge once or twice during the weekends and only at night. Electricity rates are fixed (no smart meters yet), so no need to worry about when to charge. So I thought about having an extra cable instead of taking it out of the car. Do I need an actual charger or just a cable? Not sure what comes with the car as I haven't picked it up yet.
