  "textContent": "A relay adhesion detecting device (10) of the invention is installed in an electric motor vehicle wherein a relay (14) is provided between a power source unit (12) comprising a plurality of secondary batteries and a load circuit including an electric motor for effecting or interrupting the supply of current from the power supply unit (12) to the load circuit. The device (10) comprises one secondary battery (12a) included among the batteries of the power source unit (12), the relay (14), an adhesion detecting circuit (16) and a CPU (31). The CPU (31) detects adhesion in the relay (14) due to melting by detecting the presence or absence of current flowing through a closed loop circuit comprising the secondary battery (12a), the relay (14) and the adhesion detecting circuit (16).",
