<p><P>PROBLEM TO BE SOLVED: To provide a charging device for a construction machine which minimizes energy loss. <P>SOLUTION: The charging device includes an engine E, an alternator 22 which is a generator, a low-voltage battery 23, a high-voltage battery 24, a diode 51, a switch mechanism 52, a high-voltage conversion circuit 53, and first and second controllers C1 and C2 which determine whether the accumulation capacity of the low-voltage battery exceeds a threshold or not, output signals for supplying the low-voltage battery with power of the generator to a switching control unit when it does not exceed the threshold, and output signals for charging the high-voltage battery to the switching control unit when it is not less than the threshold. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
