I was reading an intresting article on hybrids and electric vehicle's.
One of the main argument's was that when they need to be charged they still use electricity from traditional power stations putting out more co2's cause every time one of these cars is plugged in it requires more power from the station to generate the electricity needed to charge it thus putting out more pollutant's. Also most of the battery's and component's that these vehicle use are not very clean in they're production sometimes the bettery's are shipped on a ship then trucked to the factory thus the process of manufacturing these vehicle's still produce's these battery's. And at the end of there life cycle there will be more pollution to dispose or recycle these battery's. So are electric car's that much cleaner or are they for hipster's and movie star's that want people to think they give a damn about the planet. |

I'd like to know more about whether they actually do put that much more load on the grid and hence forth more power generation is required. Someone would need to confirm but I'd imagine that generation from power stations cannot just be simply ramped up or down in an instant, that they need planning.
I would also imagine if the householder is acquiring the power from alternative sources (solar, hydro, wind, etc) it off sets any supplemented power from coal if required. As for the energy required to build the cars, again depends on factories. But yes, like anything it requires power generation and pollutants, but whether it is adding any more to the atmosphere again needs to be confirmed. If the car maker uses alternative sources (BMW in the US for their paintshop use an onsite power station powered by Methane from a neighboring rubbish tip) then it offsets it again. Battery recycling for Li Ion is in its infancy but likely to gain further interest as more and more of the larger automobile based packs are available. http://www.sciencedirect.com/science...14993714000037 Electric cars are no doubt better for the environment themselves, in a city with large traffic volumes, gasoline vs electric you can see the difference with local pollutants. A Telsa for example vs a BMW 535, the Telsa will always perform better regarding pollutants local to the car. I think that is what countries and people are trying to get at. The major infrastructure of power stations and recycling will take some time (the former shift has already begun) but it won't take long.

generating the electricity to charge the battery for 100kms should still generate much less CO2 than running an internal combustion engine for 100km due to the greater efficiencies of the power stations.
interestingly when you take a cradle to grave approach to environmental impact, the older Jeeps are alleged to be 'cleaner' because they are low tech, don't use any complex materials, and haven't needed new tooling for years. Even if they run 'dirty' V8s the impact of those pollutants on the total lifetime are pretty small |

They're becoming cleaner in other countries because they're moving away from burning coal. That said, one thing it will lead to is less air pollution in cities.

Solar, wind and hydro-electricity are viable options these days. I already have solar and a wind-turbine... if I had running water on property I would have a hydro-electric turbine too.
It almost seems like some people WANT electric cars to fail because they're afraid of losing internal combustion engines. |

i Dont truly know , all those things cost a lot money , and also use a lot of resources that are usually dug out of ground using fossil fuels , much like the very dirty process of manufacturing batteries which the ev makers conveniently like to not mention ,
but they do like you to see the very pretty factories with robots and cool solar panels also manufactured using fossil materials and plenty of labor that supply x amount of electricity to build these things . it looks good at face value when you read some articles, but how good is it when you look at how much deniro , labor and resources are actually used to get these things up and running . how much fossil resources goes into the wiring and rare earth materials electric motors ,wiring that goes into all the electric vehicles , and charging equipment . my view is in the end (the big picture ) it may balance out to be bugger all difference pollution wise , and requiring lots of money to build stuff also has a pollution value if that makes sense, there are no free lunches imo. |

when you can buy a 2 ton suv that goes 800/1000 k`s , does not cost a lot of money , does every family duty, tows the family equipment , and in the scheme of things actually doesn't cost that much to run for the versatility in the one single vehicle .....which one would you buy ? |

Nope.
Well they are if you choose to feel smug and ignore the horrifying environmental damage from the mining of rare earth minerals and other substances for the battery packs which are then shipped around the world (diesel powered container ships) and transported across countries (diesel powered trucks or trains) and then huge factories make them into battery packs and motor drives (again using electricity to run the factories). Sums were done quite a few years back that showed over the expected lifetime of a vehicle (taking into account sourcing of raw materials, manufacture, running costs, fuel/energy usage, cost of purchase, etc), if you compared a Prius to a Hummer, the Hummer was actually more environmentally friendly than the Prius...

As power generation moves away from fossil fuels to other alternatives such as solar, wind power etc yes electric cars will me become more cleaner, we might not see the benefits in our lifetime but I'm sure future generations will.

Designing, building, and tuning any motor-car is a balance of compromises. The fundamental problem with Hybrids, is that they are much more able to be fine-tuned to specific conditions (ie the standard fuel economy tests.) Push them outside their comfort zone, and they are as rubbish as any other car. Top Gear proved this by pitting a Prius against a BMW, and when driven at the same speeds (pushing them hard around their track) the BMW got better fuel economy.
As for batteries, well firstly any greenie applauding electric cars is a moron. We still generate electricity from coal (which the hippies hate) so it is highly doubtful whether an electric car is significantly better for the environment. Now as to efficiency, I honestly don't know. Internal combustion engines are very inefficient, and a lot of work and engine goes into producing petrol. I would be interested to know how that stacks up against the combined efficiency of power generation, reticulation, and battery storage.

Now if a new four cylinder only got 10/100 it would be laughed at. When we had the G6E Falcon I used to constantly be amazed that a big heavy four door sedan with a four liter six cylinder and auto was cruising the highway getting sometimes under 8lt/100km. Internal combustion has become stupidly efficient compared to even ten years ago. |

I can see the benefit now that people have mentioned it of EV'S in congested city's where you spend all your time in traffic.
I have relo's in LA and NYC and they have said over the last decade the traffic is out of control my uncle spent 7-8 hours getting home from Manhattan to Staten island he said just idling the car was getting hot it was hot inside from the exhaust and exhaust's around him so I can see the benefit of EV for heavily congested city's. But the program focused more on people taking the moral high ground saying they drive an electric car when they have no clue how much resources are used in it's manufacture and charging. |

In terms of "embodied energy" it's not such a clear case of one over the other. It is difficult though, to compare "apples to apples" given the propaganda about. Oil based fuel has had many decades to improve extraction efficiency, and I do laugh at the current adds - use caltex fuel, it cleans while it burns.
to state a Tesla is faster then a Porsche turbo - that has got my attention, but I need range+speed, not just speed.... Love where the market is going for electric bikes, particularly in urban environments (sorry, I recognise this is a car forum), but really, 1-2 Tonnes needed to push a 80Kg human around? really? |

Well you may give yourself a hug and tell yourself you're doing your bit to save the world by championing electric cars and such but until this problem is solved your efforts will do jack ****. http://www.timeoutshanghai.com/featu...the-Dome-.html

People complain about petrol engined cars not reaching the range and economy claimed...yet every test I have seen of hybrid and pure electric cars usually mentions the exact same problem with them. Drive them on level ground gently and easily and you will get the claimed range. Maybe. But drive them normally, stop start, a few good hard take-offs, up hills, with a full load of passengers, and things change dramatically.
Talked to a cabbie at work about the Camry Hybrid, and he said he did consider one, but after talking to a few other cabbies about the actual range and efficiency and running costs including battery replacement, and he was going with a diesel powered sedan of some sort instead. Of course taxis run up the kilometers in a way no private car ever does, but still. Don't get me wrong...EV cars and hybrids have their place, and will get better with time. If I lived in a big city and had to commute a shortish distance to work, I'd probably consider one as a second car for work purposes...or an EV motorbike more likely. But they can't be all things to all people, as much as the True Believers would have us all thinking. |

the testers on one day of the test struck inclement weather requiring extra accessories run , heater , wipers , demister ,etc and the vehicles range went down to 65 k`s , losing range in an ev is much more inconvenient than a internal combustion engined vehicle when you can fill up the ice vehicle in 5 minutes and be on your way . theres no doubt about it , there are advantages and disadvantages for all vehicles , but conventional ice vehicles at this stage are more versatile and have less of the disadvantages . |

current fuel economy testing is based n an idealised drive cycle, hence the published figures often do not reflect what a customer really sees. This is recognised and there is a move to change to a much more realistic test cycle. I imagine much the same will happen for EVs (heater on, lights, wipers etc.)

I am not sure if this still applies but I read an article a few years ago about batteries for the Japanese built Hybrids. One of the metals was mined in Canada, shipped to the UK for processing, the processed material was shipped to China, the batteries built in China and shipped to Japan. it was quoted the amount of energy used in producing the batteries had more of an impact on the environment than running a big gas guzzler for seven years.

Toured the Prius factory in Japan a few years back when this was big news...asked the guide how was this better for the environment...she said "Not Toyotas Problem...Panasonic problem" (they make the batteries).
She also said they recycle the cardboard boxes the batteries come in! |

Depends on the state. In vic its actually worse cause of burning brown coal. But cleaner in nsw.
If you use renewables then more clean. But if you really care buy a second hand car as buying new puts out more co2 due to the manufacturing as well as running.

Network capacity is not really an issue in states such as Vic and NSW after the "gold plating" so to speak. I remember reading that around 20pc of one of the distributors networks is used onn average 2 (yes 2!) days a year.

Tesla don't use rare earths in there battery packs or drivelines. The motors are AC induction which don't require magnets. The batteries are recyclable.

batteries or motors?
If motors, Can I get in on the action? Search induction motor I hear the batteries are just 18650 's For anyone that liked Seinfeld : The Mercedes Benz 'AA' edition https://youtu.be/arQ8_PW-RiA Last edited by 383hq; 22-06-2016 at 06:46 PM. |

As soon as the battery/storage technology advances, the EV's will control the market.
