Control apparatus, method and computer readable storage medium for power exchange of battery with outside of mobile object

A method, comprising:

• storing a guaranteed amount of electric power indicating a total discharge amount of electric power that is guaranteed to be output from a battery included in a mobile object from a start of using the mobile object until a predetermined time point in future;
• calculating an amount of electric power due to travelling indicating an amount of electric power that is output from the battery from the start of using the mobile object until the predetermined time point due to a travelling of the mobile object;
• calculating, based on a difference value obtained by subtracting the amount of electric power due to travelling and an amount of electric power that has been output from the battery to an outside of the mobile object from the start of using the mobile object until a present time point from the guaranteed amount of electric power, a remaining usable amount of electric power indicating an amount of electric power that can be output from the battery for operations other than the travelling of the mobile object from the present time point until the predetermined time point;
• and
• controlling, based on the remaining usable amount of electric power, to conduct power transmission and reception between the outside of the mobile object and the battery.

A non-transitory computer readable storage medium with a program stored therein, the program causes a computer to function as:

• a guaranteed value storage unit configured to store a guaranteed amount of electric power indicating a total discharge amount of electric power that is guaranteed to be output from a battery included in a mobile object from a start of using the mobile object until a predetermined time point in future;
• a parameter due to travelling calculation unit configured to calculate an amount of electric power due to travelling indicating an amount of electric power that is output from the battery from the start of using the mobile object until the predetermined time point due to a travelling of the mobile object;
• a remaining usable amount calculation unit configured to calculate, based on a difference values obtained by subtracting the amount of electric power due to travelling and an amount of electric power that has been output from the battery to an outside of the mobile object from the start of using the mobile object until a present time point from the guaranteed amount of electric power, a remaining usable amount of electric power indicating an amount of electric power that can be output from the battery for operations other than the travelling of the mobile object from the present time point until the predetermined time point;
• and
• a control unit configured to control, based on the remaining usable amount of electric power, to conduct power transmission and reception between the outside of the mobile object and the battery.
