摘要： An engine-driven generator comprises an engine, a generator, a first conversion circuit, a first battery, a second conversion circuit, a third conversion circuit, and a second battery. The first conversion circuit converts power generated by the generator to generate a second charging voltage and charges the first battery with the second charging voltage during an operation period in which the engine is operating. The second conversion circuit converts power supplied from the first battery, and supplies the converted power to a load. The third conversion circuit converts a DC voltage supplied from the second battery into a third charging voltage for charging the first battery and charges the first battery with the third charging voltage during a stop period in which the engine is stopped.

摘要： A navigation assist system having a plurality of navigation assist apparatuses installed on small boats like motorboats each fitted with an outboard motor to be able to navigate in a predetermined water area, and a server placed on land to communicate with the navigation assist apparatuses. Each of the navigation assist apparatuses detects a trim-up position of the outboard motor, adds the position to a danger level data downloaded from the server unit, and alerts an operator concerned when the boat approaches a region whose danger level is great.
