Apparatus, system and method of managing battery level of wirelessly communicable radiographic cassette

A method of managing batteries used for supplying wirelessly communicable cassettes comprising steps of:

• detecting a current charge level of a battery presently used in the cassette;
• calculating an estimated amount of power consumption by the cassette for each of received orders for inspections;
• calculating an estimated remaining charge level of the presently used battery, which will remain at the completion of each of the ordered inspections, on the basis of the current charge level of the presently used battery and the estimated power consumption calculated for each inspection;
• determining on the basis of the estimated remaining charge level the last inspection among the ordered inspections, until which the presently used battery can effectively supply the cassette;
• and
• displaying a time limit to replace the presently used battery at latest by the end of the last inspection until which the presently used battery can effectively supply the cassette.

A battery managing system for wirelessly communicable cassettes, said system comprising at least a wirelessly communicable cassette for use in inspections and a battery managing apparatus for managing batteries used for supplying said wirelessly communicable cassette, wherein said battery managing apparatus comprises:

• a battery level detector that detects a current charge level of a battery presently used in the cassette;
• a power consumption calculator that calculates an estimated amount of power consumption by the cassette for each of received orders for inspections;
• a battery level calculator that calculates an estimated remaining charge level of the presently used battery, which will remain at the completion of each of the ordered inspections, on the basis of the current charge level detected by said battery level detector and the power consumption calculated by said power consumption calculator;
• a judgment device that determines on the basis of the estimated remaining charge level the last inspection among the ordered inspections, until which the presently used battery can effectively supply the cassette;
• and
• a display device that displays a time limit to replace the presently used battery at latest by the end of the last inspection until which the presently used battery can effectively supply the cassette.
