    • PROBLEM TO BE SOLVED: To provide a charging device which charges a plurality of batteries from a generator without causing excess and deficiency while suppressing a scale of equipment with the generator as a single machine. SOLUTION: A rectification processing part 40 includes rectification elements S1 to S9 which control charging to the batteries 3, 4 independently at each battery 3, 4. A charging state detection part 20 detects charging states of the batteries 3, 4 from voltages of the batteries 3, 4, and determines whether either of the batteries 3, 4 which is charged at a preset determination cycle according to the detected results should be selected. A synchronized signal detection part 10 detects a signal which is synchronized with a phase of the three-phase AC generator 1 from the three-phase AC generator 1, and outputs the synchronized signal. A charging control part 30 controls charging at the rectification processing part 40 by being synchronized with the three-phase AC generator 1 by using the synchronized signal from the synchronized signal detection part 10, and controls a charging amount for the battery which is determined to be selected according to the charging states of the batteries 3, 4 by using the charging state detection part 20.
