The present invention relates to an electronic relay system for high-voltage battery heating which can prevent overcurrent and overvoltage when preheating a high-voltage battery for an eco-friendly vehicle. The electronic relay system comprises: a battery management system; a high-voltage battery; an insulating switch unit for generating driving power by receiving power from the battery management system and then carrying out insulation between a low-voltage side of the battery management system and a high-voltage side of the high-voltage battery; a semiconductor switch unit for performing cut-off between (+) and (-) terminals of the high-voltage battery and conducting electricity between the (+) and (-) terminals of the high-voltage battery when drive power generated from the insulating switch unit is applied; a battery protection unit connected between the semiconductor switch unit and the high-voltage battery for preventing overvoltage and reverse current; and a load unit connected to the high-voltage battery for generating heat and thus heating the high-voltage battery by receiving current, when electricity is conducted between the (+) and (-) terminals of the high-voltage battery.
