Secondary Battery Pack

摘要

Provided is a secondary battery pack including a plurality of secondary battery modules including a plurality of secondary battery cells stacked in parallel to each other in a vertical direction, a cover, and a switch installed at an upper side of the one end in the horizontal direction of the cover, a housing, a Power Relay Assembly (PRA) including a relay electrically connected to the secondary battery cells and switches, for transmitting charging power supplied from the outside to the secondary battery cells when the relay is in a close state and changing the relay to an open state when the switch is pushed according to pressure applied to an upper side from a lower surface of the cover, and a Battery Management System (BMS) for controlling the Power Relay Assembly (PRA).

主权项

1. A secondary battery pack comprising:
a plurality of secondary battery modules comprising a plurality of secondary battery cells stacked in parallel to each other in a vertical direction, a cover for covering an uppermost surface of the secondary battery cells and with one side and the other side in a horizontal direction being rotatable around a central portion in a horizontal direction as a rotation axis, and a switch installed at an upper side of the one end in the horizontal direction of the cover; a housing for accommodating the secondary battery modules therein; a Power Relay Assembly (PRA) comprising a relay electrically connected to the secondary battery cells and switches, for transmitting charging power supplied from the outside to the secondary battery cells when the relay is in a close state and changing the relay to an open state when the switch is pushed according to pressure applied to an upper side from a lower surface of the cover; and a Battery Management System (BMS) for controlling the Power Relay Assembly (PRA).
