Abstract
A plurality of prismatic battery modules, each having a positive electrode connecting terminal and a negative electrode connecting terminal are arranged at opposite ends thereof, in a row such that the positive and negative electrode connecting terminals are directed alternately in opposite directions, thereby constituting a battery pack. A first and a second connection modules disposed at either end of the battery pack for connecting the battery modules in series are constituted by mutually linking, in a relatively displaceable manner, module connectors that comprise metal connection elements integrally held in a resin frame.

A battery pack, comprising:
- a plurality of prismatic battery modules, each of the plurality of battery modules having a positive electrode connecting terminal and a negative electrode connecting terminal arranged at opposite ends in the longitudinal direction of the battery modules, the plurality of batter modules being arranged in a row such that the positive electrode connecting terminal and the negative electrode connecting terminal are directed alternately in opposite directions;
- a first connection module and a second connection module arranged respectively at opposite ends in the longitudinal direction of the battery modules;
- the first and second connection modules each including a plurality of module connectors that are linked together in a relatively displaceable manner, the module connectors being constructed with metal connection elements, that are integrally held in a resin frame, for connecting the positive and negative connecting terminals of adjacent battery modules.
