Abstract

A charging system for a multi-floor tower for the parking of electric vehicles includes a super capacitor, a charging port connecting with the electric vehicle, and a charging controller. The charging controller includes a diverter switch, a first current limited portion, a second current limited portion, and a charging control portion. The charging control portion is connected with the diverter switch, the super capacitor, and the charging port. The first current limited portion outputs a first stable current and is interconnected between the diverter switch and the charging port. The second current limited portion outputs a second stable current and is interconnected between the super capacitor and the charging port. The magnitude of the first stable current is larger than the magnitude of the second stable current.
