Abstract:
1. A parking and power charging system for a car park comprising: a plurality of parking spaces to park electric vehicles, each of the parking spaces being equipped with a charging device having a different charging performance; parking state detection means configured to detect whether or not an electric vehicle is parked in each of the parking spaces every time an arriving electric vehicle arrives at the car park, and to detect empty parking spaces where no electric vehicle is parked; assignment means configured to assign a ranking of charging performance to each of the empty parking spaces detected by the parking state detection means so that the empty parking space with a higher charging performance has a higher ranking of charging performance on the basis of descending order of charging performance of the charging devices; communication means configured to communicate with an on-vehicle communication unit mounted on the arriving electric vehicle in order to obtain vehicle parameters stored in the arriving electric vehicle every time the arriving electric vehicle arrives at the car park; and parking space instruction means configured to select one of the empty parking spaces using the ranking of charging performance assigned by the assignment means on the basis of the obtained vehicle parameters which indicate the residual power of the on-vehicle battery, the necessity to charge the on-vehicle battery, the charging capacity of the on-vehicle battery, and the degree to easily charge the on-vehicle battery mounted on the arriving electric vehicle, and the parking space instruction means further configured to instruct the arriving electric vehicle to move to and be parked in the selected empty parking space.
