These are public batteries and will be constantly replaced by the Manufacture. Well assuming that the life of the tipical battery is 2100 charges(is really way more but kept low to provide a minimum kilowatt output), and each battery is just under lets say $1800at the time of introduction to the market. You would be paying something like a dollar per charge for each battery module, the extra money would be associated to the cost of the battery and energy cost for charging. The vehicle range is dependant on Load and how many battery modules the vehicle can carry. So It seems that this is a better solution than filling tanks full for at costs much higher/litre.

How much does it cost the "gas" station to keep inventory? Since the energy density within the battery is worse than that of gasoline, it stands to reason that the batteries are going to take up more space, and be harder to deliver to the station, than an equivalent quantity of fuel.
What happens if I pay for the battery, and don't return it? Do I need to put down a deposit, or something like that? What happens if I damage the pack, but subtly, so that you don't know that anything was wrong (until someone's car dies)? (Basically, it's like letting some random person decide whether or not to taint all the fuel that goes into your car with something that will ruin it, like nitromethane or corn syrup.) I know you said "fraud proof", but I'm wondering how you would pull it off. Some protection against tampering is necessary in order for that business model to succeed, and it's equally important that that protection is cost-effective.
Are you sure about the number of charges? That sounds pretty high, especially assuming that it will be probably be fully discharged, and fully recharged every time.
