""All EV's are toys.""

Not true,look at GM's EV 1 and two, look at all electric enhancements to Prius.

""Assume a 100 mile range ev results in a battery discharge rate of 80% = a battery charge cycle life of 300 charge cycles, so assuming its a daily driver expect to replace batteries once a year.""

The above is close to accurate for ancient lead acid batteries from grandpa's day Have another look below..

<<Those same critics have insisted that if you replace the batteries after the warranty expires, it will most likely cost several thousand dollars. Toyota claims prices will drop as hybrids become more popular; battery packs currently run around $4900. However the pack contains 38 modules that can be replaced individually for $138.00 each. Honda's Insight and Civic hybrids have an 8-yr./80,000-mi. warranty on most of the powertrain, including batteries, and a three-year/36,000-mile warranty on the rest of the car. The Prius has an 8-yr./100,000-mi. warranty on the battery and hybrid systems, plus a three-year/36,000-mile warranty on everything else. The electric motors and batteries don't require maintenance over the life of the vehicle....>>>

Can you tell me what it costs to replace an internal combustion engine including labor at $100 an hour..it is in the thousands...around here people are running from hondas and Toyotas with high miles because of the costs to maintain them......did you note this??...""However the pack contains 38 modules that can be replaced individually for $138.00 each.""... regarding your thoughts here..""but then again just one dead cell in a battery bank can kill the whole bank in a very short time.""Again you are stuck on lead acids.

""proper absorbtion and equalization charge cycle, thus the batteries never receive a full charge and results in shortened battery life from sulfation.""

All references to ancient lead acid problems...equalization..sulfation etc.

You are also not considering the vast improvements to regenerative braking by using MXWL's ultracapacitors..eliminating electrical surges to the modern batteries by grabbing electrical energy... on braking.. and dissipating it to electric drive motors...{hundreds of thousands of times}..which could be at the hubs as in UQM's electric motors.

""So where is the savings from a car that can only be driven 100 miles per day, will cost $4000+ to replace batteries not counting the $.12kwh to charge vs. a 40mpg car driving 100 miles per day that will use 912.5 gallons of fuel in a year and even at $3 a gallon would still only cost $2737.50? ""

Your assumtion of 100 miles per day is just that...the EV2 was getting 150 miles per charge with ancient lead acids 8 years ago.Think of the power saved by an all electric...repeat..no transmission,drive axels, differentials, alternator,water pump,power steering pump and related hydralics to steering rake, rad and related hoses etc and the required power to drive them???...also no fluids for transmission, diff's,powersteering,cooling system and no maintaince for all these sub systems
