A combined parking meter/battery charger station includes a detachable remote receiver to inform the vehicle operator of charge-level status and other information. Upon sufficient payment or credit, the remote receiver is released so that it may be carried away from the charging station. The receiver includes a visual or audible indicator which may keep the operator apprised of charge status, time remaining on the meter or account information. The audible alert may be used to indicate a full charge or to warn that little time is remaining, or other conditions. Communication from the station to the receiver may either be directly from the station or, alternatively, a station may communicate with a central office associated with a plurality of the stations and broadcast may be made therefrom.
