The present disclosure relates to a battery module having stable strength and rigidity, high sealability and assemblability, and improved productivity. The battery module of the present disclosure includes: a cell assembly; a cooling plate; a front cover having a lower portion welded to the cooling plate; a rear cover having a lower portion welded to the cooling plate; a left side cover having a lower end portion welded to the cooling plate and a rear end portion welded to the rear cover; a right side cover having a lower end portion welded to the cooling plate, a front end portion welded to the front cover, and a rear end portion welded to the rear cover; and an upper plate having a left end portion welded to the left side cover and a right end portion welded to the right side cover.

Battery module

Disclosed is a battery module, which includes a battery cell assembly having at least one battery cell, a module case configured to accommodate the battery cell assembly, and a module connector mounted at the module case, wherein the module connector includes a connector pin electrically connected to the battery cell assembly at the inside of the module case so as to be connected to an external connector at the outside of the module case, a connector housing mounted to an outer surface of the module case to surround the connector pin, and a sealing member provided between the connector housing and the module case.

Battery module, battery pack comprising battery module, and vehicle comprising battery pack

Disclosed are a busbar for cooling battery cells and a battery module using the same. The busbar for cooling battery cells is a busbar configured to cool a plurality of battery cells included in a battery module, and includes: a body portion formed in a strap shape and contacting an electrode lead of each battery cell; and a bent portion integrally formed with the body portion and extending from one end of the body portion to be bent in a thickness direction of the body portion, wherein the bent portion includes: a coupling groove coupled to a coupling protrusion that is prepared on a cooling plate of the battery module or a coupling protrusion that is prepared on a predetermined frame of the battery module, the predetermined frame supporting the busbar; and a thermal contact surface thermally contacting the cooling plate. Therefore, the busbar efficiently cools the electrode lead of each battery cell, which emits a large amount of heat, and allows simplification and size reduction of a structure of the battery module and reduction in manufacturing costs of the battery module.

Busbar for cooling battery cell and battery module using same

Disclosed is a battery module which has a simple structure, small volume and weight, and efficient cooling performance. The battery module includes a plurality of secondary batteries, each including an electrode assembly and a pouch exterior configured to accommodate the electrode assembly in an inner space thereof and having a sealing portion provided thereto, the plurality of secondary batteries being arranged in a vertical direction in a state of being laid in a horizontal direction; and a plurality of cartridges configured to be stacked in a vertical direction, each cartridge being coupled in contact with a sealing portion of the secondary battery to surround the sealing portion and being made of thermally-conductive material.

Disclosed is a battery module which may have a simple structure, be advantageous in making a small and light design, have excellent assembly and be strong against impact or vibration, by removing or decreasing coupling components for coupling cartridges. The battery module includes a plurality of pouch-type secondary batteries arranged in a lateral direction to stand in a vertical direction, a plurality of cartridges configured to accommodate the pouch-type secondary batteries in an inner space thereof, the cartridges being stacked in a lateral direction, and a housing provided to at least one of front and rear ends of the cartridges and coupled and fixed to at least two cartridges.

A battery pack, which includes a pack case forming an appearance of the battery pack, at least one battery module provided in the pack case and having at least one battery cell therein, and a coolant circulator connected to the at least one battery module to circulate a coolant into the at least one battery module, at least a portion of the coolant circulator pressing the at least one battery module in the pack case, is provided.

Battery pack and vehicle including such battery pack

Disclosed is a battery module which ensures efficient cooling performance and advantageously has a structurally firm and small design, and a battery pack and a vehicle including the battery module. The battery module includes a plurality of pouch-type secondary batteries standing in a vertical direction and arranged in a right and left direction; a plurality of cartridges configured to accommodate the pouch-type secondary batteries in an inner space thereof and stacked in a right and left direction; and a cooling plate made of a thermally-conductive material and disposed at a lower portion of the cartridges so that the cartridges are placed thereon, the cooling plate having an upper surface which is at least partially adhered and fixed to the cartridges by means of an adhesive.

Disclosed is a battery pack which has a simple structure, small volume and weight, and efficient cooling performance. The battery pack includes a module assembly including a plurality of secondary batteries, and a plurality of cartridges configured to be stacked with each other and surround an outer circumference of the secondary batteries at an outer side, the plurality of cartridges being at least partially made of thermally-conductive material; and a pack case having an empty space therein to accommodate the module assembly and at least partially made of thermally-conductive material to discharge heat of the module assembly.
