1. A battery that supplies electric power to a battery-driven work vehicle, the battery comprising:
a plurality of battery cell groups, each of which is obtained by connecting a plurality of battery cells in series to each other; a battery casing which includes a bottom, a top facing the bottom, and sides connecting the bottom and the top, and stores the plurality of battery cells in a space surrounded by the top, the bottom, and the sides; a first conductor which connects positive electrodes of the respective battery cell groups; a second conductor which connects negative electrodes of the respective battery cell groups; and a first line which connects the positive electrode and the first conductor, a second line which connects the negative electrode and the second conductor, and a third line which connects the plurality of battery cells included in each of the battery cell groups, each of the first, second, and third lines corresponding to one of the battery cell groups and is disposed along top surfaces of the battery cells, wherein surplus length portions of the first line and the second line generated depending on distances from the respective battery cell groups to the first conductor and the second conductor are drawn to an outside of the battery casing to be connected to the first conductor and the second conductor, and the corresponding first and second lines are bent at the outside of the battery casing according to a position of the battery cell group in the battery casing to be connected to the first conductor and the second conductor, and the shorter the distances from the respective battery cell groups to the first conductor and the second conductor in the battery casing, the larger bending amounts of the first line and the second line at the outside of the battery casing. |
