The present disclosure relates to a coupling device for coupling two or more tab electric terminals of distinct battery cells. A pair of U-shaped jaws retains the terminals therebetween with the electrical contact surfaces facing each other. A clamping element is configured to clamp the jaws towards each other in the first direction. During the clamping, an inclined wedge surface converts the pressure in the first direction to a pressure on the terminals in a second direction, so as to establish a reliable electrical contact between the terminals, direct or with the interposition of a spacing block. Wedge surfaces can be provided laterally, for example in the arms of the jaws, or between distinct bodies forming a spacing block between the terminals.

A contact module of a device for charging and discharging a battery is disclosed. The contact module includes: a first contact part copper plate and a second contact part copper plate disposed to be spaced apart from each other; a first air pocket and a second air pocket combined with inner side surfaces of the first contact part copper plate and the second contact part copper plate, respectively, and configured to expand or contract by a pneumatic pressure; and a support body disposed between the first air pocket and the second air pocket and configured to support the first air pocket and the second air pocket being spaced apart from each other.
