Machines | What if... we all drove electric vehicles?
videos | at work | information | view | construction
Dr Allan Miller, Director Electric Power Engineering Centre Transport is a large contributor to New Zealand’s greenhouse gas emissions and most of these emissions are from light passenger vehicles. If we all drove electric vehicles, powered with renewable energy, we could reduce New Zealand’s greenhouse gas emissions significantly. However today most New Zealanders drive internal combustion engine cars and not all of our electricity generation is from renewable sources, which raises questions around whether we could convert our vehicle fleet to electric vehicles and whether this will actually reduce greenhouse gas emissions. On the other side of the argument, electric vehicles are readily available today. They’re becoming more affordable, and New Zealand has plenty of wind and geothermal renewable generation planned. This talk will look at the history of electric vehicles and their technology, and consider the impact on our electricity power system if we all drove electric vehicles. It will also touch on the environmental impacts for New Zealand and other countries from converting to electric vehicles, first-hand experience of owning an electric vehicle, and the need for skills and training in New Zealand to cope with the rise of new technologies in the electricity sector, which includes electric vehicles. Dr Miller is the Director of the Electric Power Engineering Centre (EPECentre), a research centre that aims to promote and support the excellence in education and research of electric power engineering. He is also the Director of the GREEN Grid research programme, which is looking at integrating renewables and other new technology into the grid, and aspects of the ‘smart grid’. As Director of both the EPECentre and GREEN Grid, Dr Miller has a particular interest in new technologies, such as electric vehicles and photovoltaic solar power, the impact they will have on the electrical power system, and the need for training engineers to manage the power system and the transition to these new technologies. Allan holds a PhD and BE (Hons) in electrical and electronic engineering, and is a senior member of the Institute of Electrical and Electronic Engineers (SMIEEE) and a member of the Institution of Professional Engineers New Zealand (MIPENZ).

battery loses power over time my 3 year old leaf has lost 25% of battery milage , the resale value of the car has plummeted far worse than my lada i once owned and power price in nz will be the big put off once we all go electric meridian will have us by the balls, once we all go electric we will all be paying road user taxes to get back what the government will lose, petrol prices have dropped over that last 2 years but power prices have gone up , if we all go electric petrol will become the more economical option

I think the one issue with electric vehicles is that in the developed world, especially in Russia, people will want their cabins to be warm in winter. This usually isn't a problem with internal combustion engines the excess heat from combustion can be used to warm the cabin. But because electric motors are so efficient (>90%) this means a fair few kw of power would be used to heat the cabin, significantly reducing the range and Wh/mile.

With public charging the way it is now? Ha. Ha. Ha.

Great lecture, thank you!
-
So Elon was right you do need solar panels, storage devices and an ev.

WELL SOME PEOPLE DO NOT HAVE MONEY TO BUY EVEN A BICYCLE ,,,,,,

Good presentation - EVs make more sense where there's renewable energy. However, a few points glossed over : embedded energy and pollution in making new vehicles and on getting rid of old ones. Battery weight vrs diesel /petrol fuel weight. Dragging around excess weight uses substantially more energy. We've had 50% thermodynamically efficient diesel since the 1970s Elsbett designs. Audi A2 capable of 2.4ltrs per 100km in real world driving. Can also run on WVO. Heating and preconditioning of batteries in winter vrs heat "loss" of ICE cars? Cobalt mining for lithium batteries : 50% comes from DRC where 40,000 children work to mine it. What about making H2 from excess renewable electricity in NZ then going for very light weight and aerodynamic cars like the RiverSimple concept?

if we all drove ev,s the world markets would collapse via the lose of tax revenues on oil the EU and member states would crash through lack of emissions revenue , the price of lithium would be sky high because of the shortage - the price of batteries /leases would go right up , the price of charging up an ev would go up along with the price of electricity when the market share platos ,tens of thousands would be put out of work when the diesel is banned , smart meters would have to be fitted to every property because of power cuts so the suburbs would be cut off and electricity could be diverted to industry and government offices /depts ,the Chinese have bought up most of the lithium contracts , petrol and LPG costs would rise sharply .
the cost of road freight would have to rise because the cost of electric conversions to the HGV trailer,s /truck units ,2018 see,s the start of the ban on diesel transport in the EU London transport will have to spend tens of millions to go electric, all diesel trains are to go ,
So the electric car is going to ground shaking in more ways than one ! -
it would have been good if the Q&A at the end could have been included.
-
the other problem that is not mentioned is the price to change the battery pack that is estimate to last approximately 5 years so the car may be worth to change the first 5 year but then you can trow away the car because the cost of the battery pack accede the value of the car , so how much is the devaluation of the car?

Top notch teaching session

Even better with Hemp, capacitor batteries.

I'd buy an EV not because of environmental or economy reasons. I just want to stop being dependent on those Arabs and their oil. With oil, whatever the politicians/oil producers say (about availability and price), that is what happens. With electricity, if politicians and electricity companies get too greedy they know we can produce it ourselves. So they wouldn't dare get too greedy or they burn.
And let's stop making those guys rich by buying their oil. -
Bingo

What if we all switched to telecommuting?

What if we all drove Cycles?

Eastern Europe's electric cars.
install solar cells on the roof of the car
it will make manufacturing more expensive but it will enable people to have their cars recharged for free if they have the patience to wait a few days
or sell foldable solar chargers that plug into the charging socket
