Abstract
An assembled battery comprises mainly multiple non-aqueous secondary cells A and at least one electric device B for voltage detection containing a non-aqueous electrolyte connected to the multiple non-aqueous secondary cells A in series. When a difference in the non-aqueous secondary cell A between a voltage per cell (V) at a depth of discharge of 25% and a voltage per cell (V) at a depth of discharge of 75% is designated as ΔV, and a difference in the electric device B between a voltage per cell (V) at a depth of discharge equivalent to the depth of discharge of 25% of the non-aqueous secondary cell A and a voltage per cell (V) at a depth of discharge equivalent to the depth of discharge of 75% of the non-aqueous secondary cell A is designated as ΔV, the ΔVof electric device B is greater than the ΔVof non-aqueous secondary cell A.
