Abstract
A battery pre-heating apparatus for a hybrid vehicle according to an embodiment of the present invention comprises: a battery composed of a plurality of battery cells; a power relay assembly comprising, for the charge and discharge control of the battery, a first main relay connected to a positive electrode of the battery and a second main relay connected to a negative electrode of the battery; and a pre-heater including at least one sheet heater formed of a heating paste composition, wire-connected between an output terminal of the first main relay and an output terminal of the second main relay, and pre-heating the battery to a predetermined temperature using generation power by regenerative braking, wherein the heating paste composition contains, on the basis of 100 parts by weight of the heating paste composition, 3-6 parts by weight of carbon nanotube particles, 0.5-30 parts by weight of carbon nanoparticles, 10-30 parts by weight of a mixed binder, 29-83 parts by weight of an organic solvent, and 0.5-5 parts by weight of a dispersant, the mixture binder being a mixture of epoxy acrylate, a polyvinyl acetal, and a phenol-based resin, or a mixture of hexamethylene diisocyanate,…
