## Abstract

A method and apparatus for parking lot metering. The present invention allows multi-space meters to separately manage and control premium parking spaces, such as those for charging electric vehicles or those which supply electric power for engine block heaters in both pay-by-space and pay-an-display systems. Such premium spaces can be managed together over large areas (e.g., a city or region), or may be managed over smaller areas (e.g., the domain of an individual kiosk), or individually per parking space. Management includes pricing, time limits, hours, seasons of operation, and restrictions by vehicle type, and alternative pricing and restrictions for non-premium hours.
