Need help with an automotive related school project.

Hmm. i wonder if there can be a waiting/ refreshment room like those ads use while people are waiting to collect thier car during servicing. Or have a minimart like current petrol stations have?

 

Sure, you need to have waiting room.

Question is how long customers are willing to wait ? Half hour ?

Certainly not more 1 hr.

By contrast, pumping petrol takes less than a minute.

The only feasible approach are hybrid cars, maybe a combi of a hybrid Prius that can also be charged by socket or the motor. Pure ev also means people buying them can pretty much forget about driving it to Malaysia.

 

Can't really compare petrol vs electric topping up. Petrol is once every 10 days on moderate driving, eg is twice a day on easy driving. Possibility of forgetting to charge is much higher.

 

Hydrogen fuel cell cars are on the opposite side, they refuel fast and have a range of a petrol car, the Toyota model is touted to do 690km on one tank. If we had to focus on one tech and infrastructure layout to support I would rather go with this as opposed to ev. It's just more practical, Sorry but that's my take

 

Hmm. well yep its the lack of range thats the killer. Perhaps there should be a reserve storage/ battery that could kick in when the main has run out of juice. Or a warning light to alert of a low charge. Just like the low fuel warning light on the dashboard, until battery tech improves.

 

Even people run out petrol on the roads with petrol cars currently so its the same, just that the ev runs out earlier, i guess. Charging several cars at one time should slightly help offset the long charging times, compared to the current charging points currebtly in use.

Ugh. Its sort of impractical i guess. Maybe it can only be adapted for multistorey carparks with the long charging times.

Pumping petrol (the act itself) takes about 1 - 5 minutes depending on tank size.

 

But to wait for cashier to process your payment, sometimes can take up to 10 minutes if the person in front of the queue is

A) buying a weeks worth of groceries at the petrol kiosk

B) searching for the best Credit Card with the greatest discount

C) searching for a petrol voucher then swapping it for a Petrol card, then changing mind to swap for a Credit Card, rinse and repeat

D) All of the above in no consecutive order

 

 

Actually, at this point, I do not know why it is impossible to include Solar Panels as part of a car's design, doing away with stationary charging. And if stationary charging is required, the energy is from a power source or is it derived from natural resources (i.e. Solar panels). If I'm not wrong, the Google charging station has its wires hanging down because power is derived from solar panels installed on the roof of the shelter.

 

Personally, I would think that if the whole charging point is installed into the wheel stopper/barrier, it would be very nifty.

EV are not as green as it seems. Simple question is where do the electricity comes from? Power plants. How do power plants generate electricity? By burning fossil fuels. Is this green? Definitely no. There are of course green sources of electricity like wind and hydro but we don't have that kind of power plants here. Nuclear is highly unlikely too.

EV technology is moving forward very slowly. As many has said, the charging takes a long time and distance covered per charge is not very desirable. Some may say it will work in SG as it is small. But our infrastructure is not ready yet. And oil is one of the factors driving economy. Getting rid of petrol in SG is impossible.

Back to the project, the most logical method is to charge it at your home parking lot, workplace or shopping centres. I'm not sure about service stations since building and maintaining one will not be cheap. It will not be practical as well unless you can find one on every street.

To prevent sabotage, i can't think of any good method. A simple yet expensive way is to enclose the whole lot with card access shutter door. Another method is to do a docking system which locks itself after connecting to the charging port. But european makes and asian makes have the petrol cap on different sides of the car, so it might be hard to do this too.
