1. An electric vehicle comprising:
an electric motor that generates rotational power by which a driving wheel is driven;
a battery case defining a battery accommodating space accommodating at least one battery;
connectors that are located in the battery case, accommodated in the battery accommodating space, and electrically connected to respective terminals of the battery; and
electric power lines through which electric power of the battery is supplied to the electric motor, wherein
the terminals of the at least one battery comprise at least one positive output terminal, at least one negative output terminal, and at least one dummy terminal that does not contribute to electric power supply,
the electric power lines include a connection circuit that includes a connection portion where the electric power lines extending from the connectors are connected to each other, the connection portion being located in an adjacent region located adjacent to the connectors,
the at least one battery and the battery case are configured such that:
the at least one dummy terminal and one of the at least one positive output terminal and the at least one negative output terminal sandwich the other of the at least one positive output terminal and the at least one negative output terminal;
the terminals are located symmetrically as a whole; and
even when a direction of the at least one battery in the battery case is changed, electric power from the at least one battery is supplied to the electric motor through the at least one positive output terminal and the at least one negative output terminal, and
the electric power line connected to the one of the at least one positive output terminal and the at least one negative output terminal and the electric power line connected to the at least one dummy terminal are connected to each other at the connection portion of the connection circuit.
