Workplace recharging is perfectly possible is the employer is motivated to do it.
I work for Nokia and a while back I was on the intranet and I stumbled across some information and rules about the use of the electrical power points in a company car park at a site in the north of Finland. These power points are used to keep cars warm enough to start on minus 30 winter days. There is one power point for every parking space on that site, so clearly given a good enough reason, employers will install power in car parks.
I think the ideal way to do recharging would be for each car to have a power connector that has both high current connectors for power, and a set of 8 contacts that lead to a smart card slot and keypad inside the car. The smart card would be used to identify who is paying for the recharge. For communal car parks in blocks of flats or company car parks any dumb smart card with a serial number would do. For public car parks on the street or in motorway service stations the driver would insert a bank card and pay with chip and pin. This system would also protect the charging point on your driveway from passing motorists recharging their cars while you are at work.
Now all we need it for a standards body (Europe?) to standardize the connector, some motor manufacturers to produce cars, and some forward thinking employers or towns to install the charing points.
