Title:
INTERLOCK APPARATUS FOR HIGH-VOLTAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/054128
Kind Code:
A1
Abstract:
Provided is an interlock apparatus for a high-voltage device, the apparatus being capable of accurately detecting separation of a connector as an unsafe condition (connector disconnection, failure, or the like) even when the interlock apparatus itself, including an interlock loop, has failed. The present invention is provided with: an interlock loop 16 that is linked to an HV connector 7 for connecting an electric compressor to an HV battery 8; a voltage level generation unit that generates a voltage level that differs in accordance with the condition of the interlock loop; a voltage level determination unit that outputs a determination result (L/H signal) in accordance with the voltage level generated by the voltage level generation unit; and a controller 9 that outputs the L/H signal and diagnoses the condition of the interlock loop on the basis of the output of the voltage level determination unit.
