The improving performance of batteries, especially with regards to the charging curve, is good news. However, I think fundementally because they storage with the power plant, that they will have difficulty competing in the marketplace with the more flexible hybrids. Not too many people are willing to pay $X dollars for a vehicle that can only commute. They want some cargo capacity, they want the ability to drive to the next state.

I agree with you. As I have said many times I am only trying to put the facts before my readers, for whatever it is worth. The only way electrics can compete is if they are less expensive-either in cost or obvious fuel cost savings - or for the second or third car that a household can devote to trips that are in the milage range that an electric can deliver.

I agree. While ideally, we should all have small (probably electric) commuter cars for daily use and rent from a pool of common larger cars for the rare times when we need them (camping, road trips, moving etc.) - incidentally an option for some in large cities), it is unlikely that a car that can only be used for one use will catch on in any large way in the US. That is why I think Plug-in Hybrids are much more promising than straight EVs. They allow you to operate in all electric for most of the time (90%?) when you are commuting, doing around town errands etc. But they also allow you the increased range flexibility of being able to fill up for longer trips when you need to.

Remember though that any advances in EVs also drive advances in Plug-in HEVs so this is great news, especially the quick charging Subaru. Does anyone know if they are using the Toshiba quick-charge battery that I have heard news of recently?

While I agree totally that an electric car makes lttle sense for most families or individuals with only one car, there are some instances where it makes sense. The plug-in hybrid (if we could get one economically) is the best solution for the primary vehicle in a household.

The electric car makes sense for the second car in a family if the primary driver of the electric lives within the range the car is going to be used for - less than 20-30 miles from work or if a stay at home mom. Even that might not work if both drivers occasionally want to go beyond the range of the electric.

There must be at least a niche market, I don't know how big, that would be big enough for a manufacturer to produce these cars for the developed world. Lithium-ion batteries are certainly good enough now, there cost is still high, but that will come down with higher production volumes. Valence's loss is getting smaller each quarter - some of the big battery makers certainly can afford to subsidize their sales a little bit until sales volumes get up there. If the 5 minute recharge works out, the range issue all but disappears.


It is certainly time for change! And let this change occur with thunder and lightening. I am so ready for the electric cycle or car with a super/superior battery and easy and quick recharger system.


"an electric car makes lttle sense for most families or individuals with only one car"

Rent a car for over 100 mile trips Jim. That makes sense.

Have a used car converted to electric plugin for under 100 miles between charges. The cost? About 15k to 20k. About the same as a new electric car, were they mass produced.

That would work for most familes. Plugin hybrids for the remaining ones.


and the electric cars will grows much more up the coming 4 years

Used Cars

Electrical vehicles are needs because of rising and unpredictable price of petrol, these cars are more expensive than gasoline cars because of high cost batteries, electric vehicles produce no pollution, which will contribute to cleaner air in the cities.

There are a lot of car manufacturers out there that have gone into the development of "green" electric cars. As time goes by, the technology improves, and that opens doors to a lot more opportunities to improve the current status of the electric cars.
