Abstract
Disclosed is a battery module including a module housing capable of effectively increasing an energy density while improving the heat dissipation efficiency. The battery module includes a cell assembly having a plurality of secondary batteries; and a module housing having at least one sidewall to accommodate the cell assembly in an inner space defined by the sidewall and having a cooling channel embedded in the sidewall.
Claims19
A battery module, comprising:
- a cell assembly including a plurality of secondary batteries;
- a module housing forming an exterior of the battery module and including:
- at least one sidewall configured to accommodate the cell assembly in an inner space defined by the at least one sidewall;
- at least one cooling channel embedded within the at least one sidewall between an outer surface and an inner surface of the at least one sidewall, the at least one cooling channel being configured to accommodate a coolant to flow therethrough;
- and
- at least one channel connection member for respectively connecting the at least one cooling channel to at least one cooling channel of a module housing of another battery module along one single straight line in a front and rear direction parallel to the at least one side wall,
- wherein each of the at least one cooling channel includes:
- an inlet formed at a front end surface of the at least one sidewall to introduce the coolant;
- and
- an outlet formed at a rear end surface of the at least one sidewall to discharge the coolant,
- wherein each of the at least one channel connection member includes:
- a connection tube inserted into and past the inlet or the outlet of a corresponding one of the at least one cooling channel embedded within the at least one side wall, the connection tube being partially inserted into the corresponding cooling channel and extending in the front and rear direction within the at least one side wall;
- and
- a stopper having a hollow structure to surround an outer surface of the connection tube, the stopper being disposed at the outer surface of the connection tube, protruding upward, downward, leftward, and rightward from the connection tube, and butting against the front or rear end surface of the at least one side wall to set a separation distance between the module housings of the battery module and the other battery module according to an extending length of the stopper in the front and rear direction, and
- wherein each of the at least one cooling channel extends linearly from the inlet to the outlet in one single straight line in the front and rear direction parallel to the at least one sidewall.
