Document Type and Number:
Japanese Patent JP7051377
Kind Code:
B2
Abstract:
To restrain influence exerted on an electric power conversion circuit by a peripheral circuit connected to an electric power transmission route between a main machine battery and the electric power conversion circuit or influence exerted on the peripheral circuit by abnormality of the electric power conversion circuit.SOLUTION: One of a pair of DC electric power lines 30 is connected to section on a travel inverter 40 side of a positive electrode relay 12P of a positive electrode line 24P, and the other of them is connected to a section on a main machine battery 10 side of a negative electrode relay 12N of a negative electrode line 24N. A charge circuit 32 is connected to a pair of charge lines 25 and a pair of second charge lines 26. One of the pair of charge lines 25 is pulled out from between the positive electrode relay 12P and a travel inverter 40, and the other of them is pulled out from between the negative electrode relay 12N and the travel inverter 40. One of the pair of second charge lines 26 is pulled out from between the main machine battery 10 and the positive electrode relay 12P, and the other of them is pulled out from between the main machine battery 10 and the negative electrode relay 12N.SELECTED DRAWING: Figure 1
