Some time back I was thinking of developing a hybrid car and the platform of choice I thought of then was the Corolla AE89 because it was a simple platform, lightweight, it's plentiful and cheap to buy.

This idea never left the paper. I did some of the preliminary research like required hardware and the costing to see if it would be economically viable for such to become a "conversion service" beyond just being a personal project and toy. Unfortunately, even at the height of gasoline prices then, it was not economically viable because of the high cost of conversion.

In truth, converting any typical car into an electric car is not that difficult. The parts are practically off the shelf these days but the cost of conversion is still very high and the performance/range still needs much improvement. That means owning and driving a pure electric (converted) car, at this moment in time, will be a major lifestyle change for that person.

The simplest and direct way to convert a typical car to electric is to directly replace the engine with an electric motor bolted to the existing manual transmission. Aircon and powersteering are converted to electric as well and will have their own sub-systems to operate normally. From what I have read, the typical range for these types of conversions are under 100 kilometers without the electrical load from A/C or powersteering. Adding the load from accessories like powersteering, A/C, headlights, etc will greatly reduce the range.

Would you seriously consider daily driving a car that can run out of "juice" within 40 or 50 kilometers from a full charge?

It's okay if all you're doing is a regular 10-15 km commute... but heavy mid-day traffic might be a difficult proposition due to the power drain of the AC. Even on the Prius, which has an ultra-efficient electric AC compressor, mid-day traffic is killer on the battery packs.

mga sir
can an electric powered car improve its mileage....a longer battery life.....? is it possible...?

**niky** · July 15th, 2011 12:36 PM

Yes. Through electronic charge controllers and temperature control. These are the heart and soul of modern EV development... proper electronics. Battery controllers, though, are freaking expensive.

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...
