So, in Northern California where I live, gasoline is $2.50/gallon, so to fill the Camry's 17 gallon tank it's $42.50, and for 680 miles that's $0.0625/mile. If I can get the baseline rate in my area, I pay $0.12025/kwh. Assuming there's a 10% loss on charging (no idea what the actual loss is, so just choosing 10%) the 60kw battery, that's $7.9365, and for 238 miles that's $0.0333/mile. That's a savings of $0.0292/mile.
If you drive 1000 miles a month (average), that's $29.20 in savings a month, or $350.40 a year in fuel costs (assuming base gas/electricity prices inline with what I have here). If you think gas prices will average $3.00/gallon for the lifetime of the car, the fuel savings are $41.80/mo per 1000 miles, $500.40 a year in fuel costs for 12,000 miles, and evens out at just under 125k miles. For $2.00/gallon the 1000 mile savings are $16.70, $200 for a 12,000 mile year. That said, I think I average about 20,000 miles a year on the family car that we use to ferry kids to/from school and most daily errands.
The very important thing to consider though is whether or not you have access to free public charging. If you can find a free public charger and work it into your schedule in some way (maybe run some errands by foot in the area), you might be able to eliminate almost all of your home charging. If I was able to do really good at this, and only home charge for 10% of my usage on average (probably a tall order), and assuming that availability of free chargers doesn't change drastically for the worse, at current gas prices that would put my average (12,000 miles) yearly savings at $710.04. I consider $3.00/gallon a more likely average over that time, and that puts the yearly savings at $860.04, and it evens out at just under 73k miles. .
That's not super compelling when compared to a Camry Hybrid, but it may be cheaper overall, depending on how the future unfolds. That said, if what others are saying and Hybrids have increased maintenance costs, it may be enough to make electric the clear winner in this comparison, but I don't know.
