BATTERY PACK HAVING MOVABLE BUSBAR ASSEMBLY AND SECONDARY BATTERY INCLUDING THE SAME

A battery pack has a movable busbar assembly and a secondary battery including the same. More particularly, a battery pack has a movable busbar assembly configured such that at least one of a first busbar frame located at the front surface of a pack case, a second busbar frame located at the rear surface of the pack case, a first busbar connected to the first busbar frame, and a second busbar connected to the second busbar frame is movable in a direction toward a side plate of the pack case, whereby it is possible to minimize short circuit between leads, and a secondary battery including the same.
