Abstract: The present disclosure provides a battery module, which comprises battery units and two side plates. Each battery unit comprises: at least one pouch-type secondary battery; and a fixture securely mounting the at least one pouch-type secondary battery. The two side plates are respectively positioned at two ends of the battery units in a length direction. A first engaging portion is formed between the fixtures of every two adjacent battery units at each end in the length direction. Each side plate has second engaging portions, each second engaging portion is engaged with the corresponding first engaging portion to securely connect each side plate and the every two adjacent battery units, therefore the force of each battery unit received when the battery module is impacted or vibrated is effectively and uniformly dispersed and transferred to the side plates, which improves the structural strength and reliability of the battery module.
