We've all heard the stories about how electric cars were set to take over at the turn of the last century (before ironically being killed by the electric starter motor), and at least once over the last four decades too.
Now they're really here, and the fact that many major manufacturers are now investing heavily in the technology, suggests they're here to stay.
Nevertheless, it's still interesting to re-visit some of the claims made in previous years, like those made by the editor of Industry Week in 1974.
1974 found itself in the midst of the energy crisis, and America joined the rest of the world in frantically scrambling for more efficient cars as gas prices rocketed.
It was a decade in which the Honda Civic and Volkswagen Rabbit made names for themselves, and also when the last heavy wave of electric vehicles started to hit the road.
"The best available can rarely go 100 miles at 50mph," wrote James Overbeke, Resident Editor at Industry Week that year. In this respect, times have changed little. Many electric cars hitting the market still go around 100 miles, provided they stick to lower speeds. However, modern electric cars also carry more weight and offer more performance, just as modern combustion-engine cars do.
"Also," wrote Overbeke, "they require 5- to 7-hour periods on the recharger". Again, little has changed there, though on 220-240V grids electric cars are cutting down charging times, and fast chargers bring that time down even further.
Overbeke's assertion that most charging is done at night still stands true too--it's still the best time for energy companies to supply power, when demand is low, and it's also cheapest for EV users.
At the time, many were claiming that "high-density batteries are just around the corner"--another statement that still rings true, though technology has certainly moved on, and now we're often using more energy-dense, longer-lasting and more compact lithium-ion batteries, than the lead-acid ones that prevailed in the 1970s.
The final prophecy? "Of course, the real glamor item is the battery-powered urban automobile".
Well, perhaps we'd not go as far as saying they're glamor items now, but urban electric vehicles may still play a large part in bringing the technology to a true mainstream. Overbeke notes that delivery vans, buses, taxis and similarly city-bound vehicles may also be suitable.
Without as many of the range and recharging issues of larger, quicker and longer-distance electric cars, they can be cheaper--and making them cheaper potentially means a greater audience.
Whether that audience will be in the United States or not is open to debate, but in Europe the urban electric car could take off in a big way--starting with the Renault Twizy, with vehicles like Opel's RAK-e, Volkswagen's Nils and Audi's Urban Concept potentially on the way.
