Power conversion device

A power conversion device comprising:

• a first component;
• a second component;
• at least one engagement member configured to engage a male engagement member with a female engagement member to allow the first component and the second component to be electrically connected to each other, the male engagement member being connected to one of the first component and the second component and having a conductive and substantially flat plate-shaped insertion portion, the female engagement member being connected to another of the first component and the second component and having conductive first and second clamping portions disposed to face each other, and the engagement of the male engagement member and the female engagement member being made by clamping the insertion portion by the first and second clamping portions;
• a voltage measurer configured to measure a voltage across the engagement member;
• and
• a notifier configured to perform notification on condition that the voltage measured by the voltage measurer exceeds a voltage threshold.

• a state measurer configured to measure a state of the first component or the second component;
• and
• a notifier configured to perform notification on condition that the state of the first component or the second component measured by the state measurer exceeds a component state threshold.
