An assembled battery is equipped with an insulating support plate
supporting bus bars, omits the bolting operation and can simplify the
operation of electrically connecting the bus bars to electrode terminals.
The assembled battery includes a plurality of battery modules having
output terminals. An insulating bus bar plate (support plate) supports
conductive bus bars that are electrically connected to the terminal
surfaces. A guide movably guides the bus bar plate between a first
position in which the bus bars are electrically connected to the terminal
surfaces and a second position in which the bus bars are separated from
the terminal surfaces. A lock supports the bus bar plate in the first
position and maintains the bus bars in a state that is forcibly connected
to the terminals surfaces.
