1. A high-voltage battery pack for mounting under a vehicle body in a vehicle equipped with a sliding door, the high-voltage battery pack comprising:
a lower casing in which a battery module is mounted, the lower casing defining a rail mounting space to mount a door rail on a lateral side of the battery module, the rail mounting space extending in a front-rear direction; and
a bus bar and a sensing wire both mounted in the rail mounting space to electrically connect the battery module and electric components mounted on the lower casing,
wherein the lower casing comprises first and second transverse cross members extending in a horizontal direction of the lower casing while being spaced apart in the front-rear direction, the first and second transverse cross members defining a first battery mounting space, a second battery mounting space, and a third battery mounting space in the lower casing, and
wherein the first battery mounting space and the second battery mounting space have a same size and the third battery mounting space has a relatively smaller size compared to the first battery mounting space and the second battery mounting space.
