I was recently sent on a course to learn how to safely disable the 415v 3 phase power in the Leaf. This was after I'd had to recover one of the damn things.
The bloke running the course was just back from the Isle of Wight in one of them; to get to South Mimms, he'd had to charge the thing before he left, and stop at home in Guildford overnight. He reckoned the most he'd ever got out of it was 110 miles. Consider that even with the 'fast' charger(which costs about £1200 to install) it would take about 8 hours to recharge. This makes them utterly useless as anything other than a towncar. Plus, you require off street parking so you can plug in the charger.
There is a lot of clever thinking in the car; the powertrain is deliberately sized and shaped like a normal engine as it makes packaging and things like crash testing easier. The Leaf uses a lot of off the shelf Nissan parts; the suspension is lifted directly from another model. It is surprising just how well it drives, there is something deeply impressive about instant, silent torque - it accelerates well, and cruises at sensible motorway speeds.
The electric motor is perfectly suited to vehicular use; in no particular order it is powerful, compact, cheap, reliable, durable, quiet and economical.
But all it actually does is highlight just how crap battery technology still is. If we can't power a smartphone for a couple of days on one charge; a laptop for 4 hours or a cordless drill for 30 minutes, what chance does a car have?
