Abstract: Provided is a grounding structure of a high voltage secondary battery for a vehicle capable of securing stable ground potential of various electric devices included in the vehicle and reducing a risk factor that may be generated due to a potential difference by connecting a battery pack including a secondary battery and an inverter for the vehicle provided in the next generation vehicle such as a hybrid electric vehicle (HEV), an electric vehicle (EV), a plug-in hybrid electric vehicle (PHEV) to each other by a ground wire formed of an electric wire in order to allow a vehicle body and a battery pack to have equipotential.

Abstract: Provided is a high voltage secondary battery used for a hybrid electric truck among hybrid electric vehicles (HEV), and more particularly, covers are configured to electrically connect to each other by the earth member to ground the covers so as to move current induced to the covers to a chassis of a car body along the earth member due to the high voltage battery module and set a potential difference of each cover to be 0 (equipotential), thereby preventing a fault of a secondary battery and an electric shock at the time of maintenance thereof from occurring due to noise.
