Abstract
A battery module includes: a battery cell stack in which a plurality of battery cells are stacked; and a module frame for housing the battery cell stack, wherein a vent is formed on the lower surface of the module frame, wherein the battery cell comprises: a cell main body; electrode leads formed to protrude from both ends of the cell main body; and a terrace part formed to extend from the cell case in a direction in which the electrode leads protrude, and wherein the vent is formed adjacent to a portion where the terrace part is located rather than the cell main body.
Claims16
A battery module comprising:
- a battery cell stack in which a plurality of battery cells are stacked;
- a module frame for housing the battery cell stack, the module frame having an upper surface and a lower surface;
- a first end plate and a second end plate located on a front surface and a rear surface of the battery cell stack, respectively,
- wherein the battery cell stack is supported on the lower surface,
- wherein a vent is formed in the lower surface of the module frame,
- wherein each battery cell of the plurality of battery cells comprises:
- a cell main body;
- electrode leads formed to protrude from opposite ends of the cell main body;
- and
- a terrace part formed to extend from the cell main body in a direction in which the electrode leads protrude,
- wherein the vent is formed adjacent to a portion where the terrace part is located, and
- wherein the vent discharges gas in a direction of the end plate located farther from the vent.
A battery module comprising:
- a battery cell stack in which a plurality of battery cells are stacked;
- a module frame for housing the battery cell stack;
- and
- a pack frame, the module frame being within the pack frame;
- and
- a first end plate and a second end plate located on a front surface and a rear surface of the battery cell stack, respectively
- wherein a vent is formed on a lower surface of the module frame,
- wherein each battery cell of the plurality of battery cells comprises:
- a cell main body:
- electrode leads formed to protrude from opposite ends of the cell main body;
- and
- a terrace part formed to extend from the cell case in a direction in which the electrode leads protrude,
- wherein the vent is formed adjacent to a portion where the terrace part is located,
- wherein the first end plate and the second end plate comprise a module mounting part for fixing the battery module,
- wherein a support member having a first end and a second end is inserted into the module mounting part,
- wherein the second end is below the lower surface of the module frame, and
- wherein the lower surface of the module frame is spaced above a bottom part of a pack frame by the support member.
