Battery module assembly having coolant flow channel
First Claim
1. A battery module assembly comprising unit modules, each of which comprises unit cells mounted to a cartridge in a state of being electrically connected to each other via bus bars, the battery module assembly comprising:
- a base plate;
two or more sub-modules loaded on the base plate, each of which comprises two or more unit modules vertically stacked relative to the base plate to form a coolant flow channel at an interface therebetween, the coolant flow path extending parallel to the base plate, the sub-modules being arranged in a lateral direction in a state of being spaced apart from each other to provide the coolant flow channel;
side cover plates mounted at sides of the sub-modules, each of the side cover plates having at least one coolant inlet port, through which a coolant is introduced; and
a bracket for fixing ends of the sub-modules, the bracket being located between the sub-modules, the bracket having a coolant outlet port communicating with the coolant flow channel.
