Average impact on electric bill from charging and charging in an apartment complex

I am curious how much of an impact regular charging of the Model S would impact the average person's electric bill. I don't exactly foresee it going through the roof but at the same time I do view charging such a large battery as requiring more power to fully charge than something like charging the battery on my laptop.

On a side topic, how exactly would you charge the car in an apartment complex where people park in a complex parking lot? They don't have power outlets in apartment parking lots so I'm at a loss as to how you would charge the battery.

The size of the battery is not the primary issue. Estimate how many km you are driving per month. Multiply by 200 Wh/km and you get an estimate of how many kWh you have to pay for.

With current technology you need a plug where you park your car. Be that at home or eventually at work. The plug does not have to be very powerful, unless you commute daily long distances. This simply because you usually have at least 12 hours between the time you arrive home and the time you leave again next morning. In my experience 230V/16A turned out to be ample. It is underway where you would like powerful connections, when would like to get most out of just a lunch stop to be able to drive beyond your single charge range.

At the end of the day the price to charge is massively variable. First of all, the price per kWh varies from market to market, state to state, country to country. Secondly, distance and style of driving will impact how much of a recharge is needed each day.

As for charging in a public area, more and more charging stations are popping up all over. There are companies looking to capitalize on this as a new market opportunity and provide paid for use charging stations.
