2. The saddle-type electric vehicle according to claim 1 , further comprising a user-operable operation member configured to switch the connector on the vehicle between the unlock state and the lock state.

3. The saddle-type electric vehicle according to of claim 2 , wherein the operation member is located higher on the vehicle than the battery.

4. The saddle-type electric vehicle according to claim 3 , wherein the operation member includes a cover configured to cover the battery, and to be opened and closed.

5. The saddle-type electric vehicle according to claim 4 , wherein the first position of the operation member is a closed position of the cover, and the second position of the operation member is an open position of the cover.

6. The saddle-type electric vehicle according to claim 2 , wherein the operation member is configured to move between a first position and a second position; and

the vehicle includes a transmission mechanism configured to transmit movement of the operation member to the connector on the vehicle, to bring the connector on the vehicle into the unlock state when the operation member is located at the first position, and to bring the connector on the vehicle into the lock state when the operation member is located at the second position.

7. The saddle-type electric vehicle according to claim 6 , wherein the transmission mechanism includes a lock member configured to move between an engaging position at which the lock member engages with the connector on the vehicle and the connector on the vehicle is brought into the lock state, and a release position at which the lock member separates from the connector on the vehicle and the connector on the vehicle is brought into the unlock state; and

the operation member and the lock member are connected to each other, the lock member is disposed at the release position when the operation member is located at the first position, and the lock member is disposed at the engaging position when the operation member is located at the second position.

8. The saddle-type electric vehicle according to claim 6 , wherein the battery includes a plurality of batteries;

the connector on the vehicle includes a plurality of connectors respectively connected to the connectors on the plurality of batteries; and

the transmission mechanism is configured to limit the movement of the plurality of connectors on the vehicle when the operation member is located at the second position, and to allow the movement of the plurality of connectors on the vehicle when the operation member is located at the first position.

9. The saddle-type electric vehicle according to claim 1 , wherein the battery is configured to be vertically attached to, and detached from, the vehicle;
