METHOD FOR REPLACING BATTERY PACK OF HYBRID ELECTRIC VEHICLE

The present invention relates to a method for replacing a battery pack of a hybrid electric vehicle, characterized in that a nickel-metal hydride battery pack in which 28 cell modules with a nominal voltage of 7.2V are arranged in series and in which pack terminals N to N for voltage sensors are installed alternately in order in the cell modules, is replaced with a lithium-ion battery pack in which a plurality of cell modules with a nominal voltage of 28.8V are arranged in series and in which module terminals R to R for voltage sensors are respectively installed in the cell modules.
