And to think; if someone mass produced an electric car with Lithium Ion batteries, it would break even with comparable gas cars at $2.50-3.00/gallon gas, factoring in periodic battery replacement. If large format NiMH batteries are used, a study by Cuenca and Gaines found cost parity with comparable gas cars at $1.30/gallon gas. Too bad Chevron has suppressed large format NiMH batteries; can't let the market truly be free and have consumers flocking to the more economical and convenient technology now, can we?
Even an electrified Tahoe(.4-.45 kWh/mile) with a 90 kWh Li Ion pack($250/kWh in automotive volume) and $.10/kWh electricity, assuming 90% charging efficiency with Li Ion batteries, would cost a mere $10 to "fill up" for perhaps 200-230 miles range. In automotive volume, this would be a $22,000 battery pack that lasts about 125,000 miles. Basically, $5.64 to drive 25 miles, factoring in battery costs and $.005/mile maintenance for EVs. The gasoline version requires about $.05/mile in maintenance, so to drive the gasoline version 25 miles at $3.05/gallon will cost an additional $1.25 on top of the calculated $4.77 gasoline costs, for $6.02 total for the gas version.
Even for an aerodynamically inefficient brick like a Chevy Tahoe, an electrified version with Li Ion batteries will reach cost parity with its gas counterpart at $2.80/gallon gas, in mass production. A NiMH version(assume 75% charge efficiency, $225/kWh in automotive volume), with a 45 kWh pack, 100 miles range, and 175,000 mile pack life, would cost $2.90 to go 25 miles including electricity, maintenance, and battery, and achieve cost parity with its gas counterpart at $1.06/gallon gas.
Even wasteful SUVs could be competitive as EVs using Li Ion batteries. Currently, anything up to midsize electric cars and small electric SUVs can easily match or beat the operating cost of comparable gasoline cars using Li Ion, and large inefficienct vehicles are getting there too as gas prices rise. With NiMH, the savings of an EV would be out of this world, but NiMH won't give as much range or power as Li Ion(still more than enough horsepower to match the average IC car though, and get about half its range).
The unnecessary felling of a tree, perhaps the old growth of centuries, seems to me a crime little short of murder. ~Thomas Jefferson
