Abstract: PROBLEM TO BE SOLVED: To provide a computer system having a plurality of energy devices integrated on a system communication bus and capable of making communications between the energy devices without obstructing the other functions of electronic apparatus. SOLUTION: Energy devices are integrated on the system communication bus, and each has a memory and a processor. The processor monitors the system communication bus selectively and examines whether there is no communication data, and if none, the energy device tries to make communication with another energy device belonging to the energy system. After sensing that no communication data exists, the energy device tries to make communications by the specified sequence. One energy device includes, for example, a battery pack, desk top charger, analyzer and radio appliance.
