Abstract
Structure for and method of charging an electric vehicle at a parking location and facilitating billing for the charging energy utilized and the parking time. The structure includes a charging and parking meter at a parking space for receiving a charge card and into which a charging plug from an electric vehicle may be placed, structure for reading the charge card placed in the meter and for locking the plug in place, and a central processor unit for determining the charging energy used and parking time and for storing billing data relative thereto at a remote location, for periodic removal to facilitate billing. The method of the invention includes the steps of permitting charging of an electric vehicle at a parking location in response to use of a charge card and storing charging and parking information for subsequent retrieval to facilitate billing to the owner of the charge card.
