Provided is a high voltage secondary battery (1000) used for a hybrid electric truck among hybrid electric vehicles (HEV), and more particularly, covers (100, 300) are configured to electrically connect to each other by the earth member (400) to ground the covers (100, 300) so as to move current induced to the covers to a chassis of a car body along the earth member (400) due to the high voltage battery module (120) and set a potential difference of each cover (100, 300) to be 0 (equipotential), thereby preventing a fault of a secondary battery (1000) and an electric shock at the time of maintenance thereof from occurring due to noise. |
