Portable device for displaying charge information and charge information display system
First Claim
1. A portable device for displaying charge information, comprising:
- a transmission unit for wirelessly transmitting a signal, requesting charge information on a battery, to a controller provided with a unit for detecting a remaining amount of a battery;
a reception unit for wirelessly receiving the charge information from the controller;
a storage unit for storing charge information received by the reception unit; and
a display unit for displaying charge information stored into the storage unit, whereinduring charging of the battery, the reception unit receives, from the controller, charge characteristic data representing a charged amount of the battery with respect to charging time for the battery,the storage unit stores the charge characteristic data received by the reception unit,the portable device further comprises a charge prediction information calculating unit for calculating prediction information regarding a state-of-charge of the battery based upon the charge information and the charge characteristic data stored in the storage unit in the case of the reception unit being unable to receive charge information from the controller after transmitting a signal requesting charge information from the transmission unit, andthe display unit displays the prediction information calculated by the charge prediction information calculating unit when the charge prediction information calculating unit calculates the prediction information.
