electric powered cars

Aside from what Niky mentioned, there is also regenerative braking, solar panels on the roof, ultra-low rolling resistance tires, etc.

But the same issue, it makes the car expensive.

no.1 problem--is the high cost of conversion of engine to electric powered cars...

mga sir
tanong na rin po yung distance na mabyabyahe po ng electric powered cars ay pede na rin po bang humaba.... na makatulong po yung solar panels on the roof to recharge the batteries of the electric powered cars during daytime?

Solar panels on the roof will only marginally increase the range by a small amount. It has been done to the Toyota Prius as an optional extra to extend it's electric mode driving range. Given the typical car roof is only (approximately) 1.5 square meters in area, it's not going to provide much power to make a major increase in driving range.

It's more practical to have a recharging station at the car's destinations if you want to increase the car's maximum driving range. Even with that, it will take many HOURS to have a significant recharge if the battery is low on power. If you work at the destination, then spending the next 8 hours at the location is fine but if you are traveling across the city and the charge gets low, you will find yourself stranded until the battery gets a significant recharge.

sir

thanks sa info...and sa youtube video...wag po kayong magsasawa sa kakatanong ko po...

mga sir,
tanong na rin po... pede po ba hong sabihin na ang hybrid car is much better than an electric car?

Depends on how you look at it.

The hybrid car is a stop-gap design for the transition between fossil fuel cars and pure electric cars. Hybrid cars only make the fuel go further, but in the end it still relies to gas, diesel, etc to make it go.

Another issue with hybrids is the cost and complexity. You essentially have two power systems on a single vehicle. That increases the materials and weight. Cost is added as well. At the end of the day, a hybrid car will always be more expensive than a conventional internal combustion car.

For most consumers, they don't really care of their car is a conventional car, hybrid, or electric. All they want is for their cars to be reliable, affordable to purchase and cost effective to operate within it's design lifetime. Hybrids currently fail to be affordable to buy and cost effective to operate.

Why did I say fail to be cost effective to operate? Put it this way, if you own a Prius vs a Vios, the Vios will be financially/economically ahead from the time it was purchased up to ten years later (more or less). After operating the Prius for ten years, then it might be cheaper to use the Prius, assuming you don't have to change to battery pack every two to five years. If you don't change the battery pack, the Prius becomes another ordinary fossil fuel burning car.

Making a "green" car is not simply cutting down on emissions, it should also take long hard look at the amount of materials and energy that goes into making the actual vehicle. At the same time, look at the materials themselves if they are toxic to the environment when parts and components come to their end of life cycles.

Consider that, older cars like a Corolla or a Civic or Sentra running on alternative cleaner fuels (like LPG) would actually be better than having a hybrid.

A diesel engine, altough not so easy to convert to LPG or CNG, can run on some alternative fuels such as vegetable oils (either straight or waste), biodiesel and even ethanol, while all the processes involved in the manufacturing of the battery pack of a Prius generate more emissions than a diesel-powered Euro-spec Toyota Corolla 1.4 D4-D would do in a predictable 20 years lifespan, while the battery pack of the Prius wouldn't last more than 10 years so easily.
