...In the previous article I pointed out that Electric Vehicle Battery Packs need to have an energy density of around 675 Watt-hours per kilogram (Wh/kg) if they are to have an equal range to today's petrol-powered cars. I also pointed out that the Nissan Leaf - the world's first truly mass-produced electric car - has a battery pack with an energy density of around 131.57 Wh/kg. This means that the Leaf only has an effective range of approximately 117km (72 miles). "Range Anxiety" is truly a problem for Leaf owners - even though the total cost of charging the Leaf is lower per kilometre than the cost of filling up regular cars with petrol (the equivalent fuel efficiency for the Nissan Leaf is 2.4 litres per 100 km - 99 miles per gallon)...Nov 29, 2011
