""Since the EV is a dead horse why are we beating it?""
No, not a dead horse, but the future... as everyone knows..and the "once great" GM knew about 70 percent of "all driving" is short hops 40 miles and less...so logical for "second car" to be all electric...charged at night when rates are low,or charged by solar or wind turbine...the ever creeping "coming thing."
""On the other hand a lot of electronic components are involved so failures would tend to be electronic vs mechanical.""
Lets see, drive motors on wheel hubs...lets say 2 of them, which change into resistance generators when brake is pushed, feeding generated electricity to ultracapacitors which dump it back to hub wheel motors on acceleration, plus battery bank .Yes a bit of simplification..there would be other electrical components of course but nothing compared to..
Gasoline in the gas tank is pumped to internal combustion engine by fuel pump which could be electrical and located in the gas tank, or it could be driven off the cam shaft of the engine.. or just electrical in line ...the gas is mixed with air via a carburator or it could be injected into each cylinder ...fuel injected so no carburator...this mixture is burned in cylinders which move up and down 2,3, 4 or 8cylinder ..intake, compression, power, and exaust strokes ..turning the crank shaft which also turns the cam shaft (which opens and closes valves) ...which also turns the transmission which in turn, turns the transaxles which turn the drive wheels ...front wheel drive ...but the transmission could turn the drive shaft which turns gears in the differential which turn the axles which drive the rear wheels..rear wheel drive...or,more complicated and expensive and inefficient still... all wheel drive...at the other end of the crankshaft there is ususally a pulley on the end with many belts coming off it or just one ...they turn the alternator, the power steering pump, water pump etc..these component systems all operate with various fluid systems usually under pressure...never forgetting the exaust system, starting with exaust manifold, to pipe,to expansion chamber, to pipe to catalitic converter, to pipe to muffler to finally exaust pipe out the back.And we must not forget, we need tranmission fluid, engine oil, differential oil, power steering fluid,antifreeze coolant, and brake fluid for that wasted heat energy pad and shoe braking system.
Don Devlin is correct..

All electric just makes sense.
edit..
I missed this...
<<<A couple of new points I'd like to bring up is lets assume battery life to be 10 years.
What will be the intrinsic value of a 10 year old vehicle that needs a $4000 battery bank?>>>
The same as a ten year old vehicle that needs a new engine. |
