Also, that isn't good for the batteries. I imagine it would make them get pretty damn hot.
How much power does this thing use to charge? :Q
I wonder how much cheaper than gas it really would be when you figure in electricity cost.
The average round-trip commute in the U.S. is 20 miles according to the 2000 report from the Bureau of Transportation Statistics.
For that average commute of 20 miles and up to 24 miles per charge, the total cost per mile of the Tango is approximately 30% lower than that of a Honda Insight. This includes battery replacement, maintenance, and the cost of electricity at $.05 per kWh (as in the Northwest). The Honda Insight has an EPA rating of 56 mpg city and 57 highway. Please see the Cost-per-Mile Spreadsheet for details. This spreadsheet shows how the Tango compares with other vehicles, both Internal Combustion Engine (ICE) driven and hybrid. It includes gasoline and recommended dealer maintenance costs for the gasoline cars and electricity, maintenance, and battery replacement costs for the Tango.
In California where electricity rates are nearly $.15 per kWh, the total cost per mile for the Tango becomes roughly equal to that of the Insight. Electricity cost per mile runs from 0.9 cents to 2.6 cents as cost per kWh goes from 5 cents to 15 cents.
Battery replacement is the largest portion of the cost-per-mile for an electric car. To demonstrate how this works, we use Optima's cycle life vs. depth of discharge graph. This graph applies to laboratory-controlled charge and discharge cycles, yet is quite indicative of the effects of driver habits. If the Tango were driven to 80% DOD (depth of discharge) or more (approximately 64 to 80 miles regularly between charges), the pack will only yield 250 cycles. This works out to approximately 16 cents per mile with current Optima Yellow Top prices of $100. However, if discharged to 25% DOD (20 to 24 miles between charges), the chart shows 4,000 cycles can be achieved yielding 80,000 miles with a cost of only 3.1 cents per mile.
