A program storing medium storing a computer readable program for controlling a computer for controlling a power supplying system, comprising a charging/discharging apparatus and a power supplying apparatus,
- wherein a program for controlling said charging/discharging apparatus comprises:
- a standard charging capacity storage controlling step for controlling storage of a standard charging capacity;
- a charging capacity storage controlling step for controlling storage of the present charging capacity;
- a charging voltage value measurement controlling step for controlling measurement of a charging voltage value;
- a first transmission controlling step for controlling transmission of the information on said standard charging capacity, said charging capacity and said charging voltage value to said power supplying apparatus;
- a first reception controlling step for controlling reception of a command for correcting said charging capacity from said power supplying apparatus;
- and
- a correction controlling step for controlling correction of said stored charging capacity based on the command received through the processing in said first reception controlling step;
- and
- a program for controlling said power supplying apparatus comprises:
- a second reception controlling step for controlling reception of the information on the standard charging capacity, the charging capacity and the charging voltage value of said charging/discharging apparatus transmitted from said charging/discharging apparatus;
- and
- a second transmission controlling step for controlling transmission of a command for correcting said charging capacity to zero or a value corresponding to zero to said charging/discharging apparatus when said charging voltage value is equal to or less than a predetermined voltage value corresponding to said charging capacity close to zero and said charging capacity has a predetermined rate of said standard charging capacity or more.
