Need help with an automotive related school project.

The current limitation of battery life vs distance makes a electric car unfeasible for large scale roll out, not to mention in Singapore heat deteriorates cell life.

 

Makes more sense to design cars with replaceable battery cells, and the top up station will swap out the cells and charge the customer for the electricity provided on the topped up battery.

 

However unless someone breaks all limitation on current batteries or govt redo the main infrastructure (wireless induction in the road) electric car usage will be limited.

 

Realistically I believe Hydrogen fuel cell is a better way to go assuming they find a way to efficient split hydrogen from water and a safe way to store them in cars.

 

 

 

True. But we dont have endless roads or highways like in the USA where refuelling stations are sparse. Our road network and landmass is pretty small and most of our driving is done on a city based commute, so the limited range might work in the EV's favour anyway. The idea is to mainly support lots of cars on end so that there wont be a gridlock of cars waiting to recharge assuming that we will successfully make a transition to electric based vehicles in the future.

Hmm. to be honest, it's really beyond me, as much as i want to implement it in my project. Also have to take costs and practicality in mind as wireless charging is more expensive

 

To be honest, what would you think of a multi level EV charging station, like say.. one with two/ three storeys that could support tens or maybe hundred or two?( on a real world scale)?.

 

mechanised car park can pack more cars in a small foot print while they are charging.

 

[Nick2342]

 

If you're building charging points, a simple solution is to lay the wires underground and have a charging point sticking out of the ground beside each designated lot.

 

I can't answer why google would want to have wires hanging all around.

 

I'm a simple man. If I make things, I want simplicity and functionality, on top of reliability.

 

Hmm that didn't occur to me. I might look into that. My design is such that the wires retract all the way into the ceiling, with only the socket visible when charging is needed so that there won't be lots of cables lying around.

[Volvobrick]

Any design that involves a lot of movement generally equals poor reliability.

 

Unless it is designed, engineered and built by the Japanese....

Well, there is no room for escape if something does happen during charging or something, i guess.. Plus breakdowns means that some cars may not be accessed compared to the traditional carpark design..

[Volvobrick]

It is a known fact that wireless charging is much slower. Imagine charging by wire already takes few hours, wireless few times longer...

 

Have the wireless chargers buried under every junction, so whenever we stop/kena jam, the car gets charged.

 

Buried it under entire stretch of CTE and we can claim another world first - the largest wireless car charging station on earth!

[Kb27]

At this day and age, wireless is good for transmitting small signals, intelligence, etc.

 

But wireless is still bad at transmitting raw power.

The only time we charge our cars this way is when we return home from work or are shopping/having coffee. That is a function of time. The charging must be done before we next use the car

 

The time at the station includes parking which in SGP is not cheap. Would the cost of charging be cheaper than petrol?

 

Expensive motoring cost in SGP does not encourage such cars.

 

The infrastructure - would require govt help. There needs to be critical mass. The economics must agree with the science. remember CNG?

[Beehive3783]

There already are hydrogen fuel cell cars in existence, but not in mass production stage.

 

Honda has one (FCX Clarity), Merc also has one.

 

Top Gear tested the Honda in California and I have seen the Merc in Singapore before. It's an A class.

CNG was a success and getting popular.

 

Oh, then somebody stepped in and announced taxes on CNG.

 

GG.

Why would I want an electric car when my turbo cant kick in...

 

 

 

 

Ok serious side, they shud implement.this and gives incentives for people to buy electric car or else its useless to build this. Nice idea though cos this will be the first in singapore

How about bike mounted quick charge service for ev which runs out of juice on the roads?? This is for those absent minded drivers.

[Super7]

 

Unless it is designed, engineered and built by the Japanese....

Or designed n operated in countries with cheap labor, can use 6 men to push or carry the cars, still cheaper than automated operations.

Someone made the promise of CNG and then someone else killed it. Haha.

Something like full size slot cars?

 

Can follow bumper cars method also:- use overhead electrified netting/roof charging the ev via a flexible pole stick up from car's roof to reach the electrified nett/roof.

[Super7]

why not battery kiosks or petrol kiosks have pre-charged batteries and drivers just swap their depleted one for a fully charged one for a fee. No waiting time.

This what I have been thinking also:- "one for one exchange" of batteries, or make such detachable batteries on rental basis, with exchange-stations spread throughout the island.

if the batteries can be standardized across car models, than it makes lots of sense. Like 3.7v lithium phone batteries.

 

This will not 'encourage' people to overcharge (stay in the charging station longer) so they can spend more time away for coffee etc.

 

[Beehive3783]

Do you know how big the battery cells in an electric car are?

 

These are definitely not your mobile phone sized batteries.

i know. what i mean is that if car manufacturers can standardise batteries then like the micro USB, we can use the same (brick) batteries across car brands. Else it would be hard to ensure reliability of supply.

 

Very troublesome with the admin.

Invent an engine that take your urine as fuel. Every morning wake up, go pee into the fuel cock hole. Problem solved.

 

China is now harnessing it's own people pees and poos as fuel source.
