  "textContent": "An electric charging control device is obtained which detects welding abnormality of an electric contactor(s) along charging passages from an electric charging plug reaching a main battery; electric charging contactors and main electric contactors are connected in series; a first voltage monitoring circuit connected between power-supply points P and N, a second voltage monitoring circuit connected therebetween, and a voltage-level detection circuit connected between the midpoints P and N are provided for producing a first voltage detection signal DET, a second voltage detection signal DET, and a main voltage detection signal DET, each of which is a respective determination logic signal responding to the presence or absence of a monitored voltage; and a test voltage is received from either one of the main battery and a ground-based electric charging power-source apparatus, so that the presence or absence of welding abnormality in any one of the contactors is determined.",
