<p>The charger 10 has first to third charging circuits 12 to 14 including a first charging path that charges battery banks 21 to 23 via current limiting resistors R1 to R3, a second charging path that charges the battery banks 21 to 23 without passing through the current limiting resistors R1 to R3, and a circuit that is capable of selectively switching the first and second charging paths to one another, being provided to the respective battery banks 21 to 23, and being identical in resistance values of the current limiting resistors R1 to R3; a battery voltage detection circuit 15 that detects the voltages of the battery banks 21 to 23; and a controller 16 that controls the first to third charging circuits 12 to 14 so that the battery banks 21 to 23 are charged through the first charging path when there is difference in the voltages of the battery banks 21 to 23, and that the battery banks 21 to 23 are charged through the second charging path when there is no difference in the voltages of the battery banks 21 to 23.</p> |
