Control device of electric motorcycle
A battery is disposed close to a through-hole of a swing shaft that pivotally supports a swing arm on a vehicle body frame so as to be freely swingable at a position closer to the front of the vehicle body in the swing arm. An electric motor is disposed close to an axle of a rear wheel at a position closer to the rear of the vehicle body in the swing arm. The control board is disposed at a position outside of the battery in the vehicle width direction, and the heating element board is disposed at a position rearward of the vehicle body with respect to the control board and forward of the vehicle body with respect to the motor.
1. A control device of an electric motorcycle having a swing arm that pivotally supports a rear wheel of the electric motorcycle and that is freely swingably attached to a vehicle body of the electric motorcycle, wherein a battery and an electric motor for driving the rear wheel are equipped inside of the swing arm,
the swing arm being a cantilever swing arm that pivotally supports the rear wheel by a single arm portion of the swing arm,
the battery being disposed in the swing arm at a position closer to a front of the vehicle body and close to a through-hole of a swing shaft that pivotally supports the swing arm on the vehicle body so as to be freely swingable,
the electric motor being disposed in the swing arm at a position closer to a rear of the vehicle body and close to an axle of the rear wheel,
the control device of the electric motorcycle including a board serving as the control device that is disposed such that a planar portion of the board is oriented in a vehicle width direction of the electric motorcycle, wherein
the board includes a control board which has a control element having a small calorific value and a drive circuit for controlling the electric motor disposed on the control element, and a heating element board which has a heating element having a large calorific value and a charging circuit for charging the battery disposed on the heating element, wherein
the control board is disposed at a position outside of the battery in the vehicle width direction, and wherein
the heating element board is disposed at a position rearward of the control board with respect to the vehicle body and forward of the electric motor with respect to the vehicle body.
2. The control device according to claim 1 , wherein the heating element board is disposed close to the control board rearward of the control board with respect to the vehicle body.
3. The control device according to claim 2 , wherein the heating element is mounted on a surface of the heating element board.
4. The control device according to claim 3 , wherein the heating element is stored in a curved portion that couples an outer shell portion of a storage space for the battery and the arm portion with each other.
5. The control device according to claim 2 , wherein the heating element board is disposed at a position to overlap with the rear wheel in a side view of the vehicle body.
6. The control device according to claim 2 , wherein the battery is formed in a substantially rectangular parallelepiped shape with a longitudinal direction of the battery oriented in the vehicle width direction, and
the control board, with its planar portion oriented in the vehicle width direction, is disposed close to one longitudinal end surface of the battery.
7. The control device according to claim 2 wherein the battery is an assembly of laminate batteries where cells of the battery are packed with a soft laminate sheet.
8. The control device according to claim 1 , wherein the heating element is mounted on a surface of the heating element board.
9. The control device according to claim 8 , wherein the heating element is stored in a curved portion that couples an outer shell portion of a storage space for the battery and the arm portion with each other.
10. The control device according to claim 1 , wherein the heating element board is disposed at a position to overlap with the rear wheel in a side view of the vehicle body.
11. The control device according to claim 1 , wherein the battery is formed in a substantially rectangular parallelepiped shape with a longitudinal direction of the battery oriented in the vehicle width direction, and
the control board, with its planar portion oriented in the vehicle width direction, is disposed close to one longitudinal end surface of the battery.
