Abstract: A state of a plurality of switches for performing application and cutoff of a plurality of electrical loads is stored in a memory circuit. A pattern of supply power after application of the load for each of the plurality of electrical loads and a load response priority order assigned previously to each of the electrical loads are stored in a memory table. A control circuit identifies a newly applied load on the basis of the turned-on state of the plurality of switches stored in the memory circuit and instructs an electric power supply circuit to supply electric power in accordance with the supply power pattern corresponding to the identified load, while the control circuit prohibits application of the newly applied electrical load when an electrical load having the load response priority order higher than that of the newly applied electrical load has been already applied. The memory table may store consumption power and an application priority order assigned previously to each of the electrical loads.

Abstract: A charging generator having a self-diagnosis function includes a self-diagnosis circuit, a storage device and an output device. When an anomaly is detected, the charging generator with a self-diagnosis function stores data concerning at least one anomalous condition of the generator and the contents of the anomaly in the storage device, and outputs the anomalous data concerning the generator or the contents of the anomaly, which are stored in the storage device, by inputting a specific signal from the outside.
