Title:
Electric vehicle control device
Document Type and Number:
Japanese Patent JP5908383
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a control device capable of eliminating a failure caused by erroneous opening of a main switch when traveling on a battery.SOLUTION: An electric-vehicle control device, including a filter capacitor 109 and a battery 112 that stores DC power of a DC power source 100, supplies either of DC power of the DC power source 100 and DC power of the battery 112. A first main switch 101 is opened for separating the DC power source 100 from the filter capacitor 109, while a second main switch 106 is closed in link with the first main switch 101 when the first main switch 101 is open, grounding discharge resistance to discharge stored power of the filter capacitor 109. Concurrently with the above, determination means of a control part 120 determines whether the first main switch 101 is open, namely the main switch is erroneously open, when DC power is supplied from the battery 112 to a load.
