Abstract
A charge fare meter includes a charge module and a display. The charge module is used for outputting a direct (DC) current and calculating total charges, wherein the charge module includes an input interface, a calculating unit, and an output interface. The input interface is used for converting power provided by an alternating current power source or the DC power source into the DC current. The calculating unit is electrically connected to the input interface for calculating the total charges. The output interface is electrically connected to the calculating unit for outputting the DC current. The display is electrically connected to the charge module for displaying the DC current, a voltage corresponding to the DC current, or a charge fare corresponding to the total charges.
