Battery pack, and automotive vehicle comprising same
A battery pack includes a plurality of battery modules; a cooling pipe configured to supply a cooling liquid to the plurality of battery modules; and a tray comprising a cooling liquid receiver into which a cooling liquid leaking out from the cooling pipe flows, the plurality of battery modules being seated on the tray.
1 . A battery pack comprising:
a plurality of battery modules;
a cooling pipe configured to supply a cooling liquid to the plurality of battery modules;
a tray comprising a cooling liquid receiver into which a cooling liquid leaking out from the cooling pipe flows, the plurality of battery modules being seated on the tray;
a pair of side covers covering opposite end portions in a width direction of the tray; and
a pipe receiver coupled to the tray and surrounding the cooling pipe to accommodate the cooling pipe therein,
wherein the cooling liquid receiver comprises a cooling liquid inlet formed in the tray to provide direct fluid communication with the pipe receiver and through which the cooling liquid leaking out from the cooling pipe flows into the cooling liquid receiver, and
wherein the tray further comprises:
a mount plate directly contacting the plurality of battery modules, and having an end portion in a width direction spaced apart from the pair of side covers forming the cooling liquid inlet; and
a base plate spaced apart from a lower portion of the mount plate and forming the cooling liquid receiver in which the cooling liquid flowing through the cooling liquid inlet is accommodated.
2 . The battery pack of claim 1 , wherein the pair of side covers comprise main body portions extending in a longitudinal direction of the tray and respectively located on a first side and a second side of the tray.
3 . The battery pack of claim 2 , wherein the pipe receiver is configured in at least one of the pair of side covers and extends inward from an inner wall of the main body portion.
4 . The battery pack of claim 1 , wherein the pipe receiver is coupled to the mount plate and the main body portion of the at least one of the pair of side covers.
5 . The battery pack of claim 1 , wherein each of the plurality of battery modules comprises a fixing portion formed on at least one side.
6 . The battery pack of claim 5 , wherein each of the plurality of battery modules is fixed to at least one of the pair of side covers through the fixing portion.
7 . A vehicle comprising at least one battery pack according to claim 1 .
8 . The battery pack of claim 1 , further comprising a gas discharge portion above the pipe receiver.
9 . The battery pack of claim 8 , wherein each of the plurality of battery modules has a discharge port,
wherein the gas discharge portion has a plurality of inlets; and
wherein each discharge port communicates with a respective one of the plurality of inlets.
10 . The battery pack of claim 8 , further comprising a front frame connected to the tray; and
an outlet formed in the front frame,
wherein the gas discharge portion communicates with the outlet.
11 . The battery pack of claim 1 , wherein the cooling pipe is not in direct fluid communication with the cooling liquid receiver.
