Get a plug in early
THE whole-of-life impact of EVs on the community prompted Mitsubishi to involve Dr Peter Pudney in its introduction of the i-MiEV.
Dr Pudney, senior research fellow in applied mathematics at the University of South Australia, has researched the impact of EVs on CO2 emissions and the power grid.
He says the range of EVs now is l i mi t e d to about 100-200km, but believes this is more than enough for most urban motorists. His research shows that in Adelaide, 98 per cent of daily travel is less than 100km and these trips represent 92 per cent of the daily distance covered.
He says a shift to EVs using current available power would not make a significant reduction in CO2 until more use was made of renewable energy.
‘‘The message is don’t abandon clean cars; abandon dirty energy,’’ Dr Pudney says.
He believes the present national electricity grid could cope even if all urban vehicles b e c a me E V s , s o long as recharging was done at low demand t i mes. ‘ ‘ Power d e - mand drops dramatically overnight, so we would need to charge EVs at night,’’ he says.
Mitsubishi Motors Australia corporate affairs vicepresident Paul Stevenson doesn’t believe recharging infrastructure will be a hurdle to the introduction of EVs.
‘‘We have grown used to plugging in our mobile phones at the end of each day,’’ he says. ‘‘EVs will be the same.’’
