Abstract:
1. A battery module mounting structure for a motor-driven two-wheeled vehicle, having an electric motor driving a rear wheel of the vehicle and a PDU disposed in a swing arm rotatably supporting the rear wheel and swingably supported by a vehicle body via a swing shaft passing through a through-hole formed in a front side of the vehicle body, the battery module mounting structure comprising: a housing case housing a battery supplying electric power to the electric motor and the PDU for controlling the electric motor; wherein the housing case is configured to be mountable to and dismountable from the swing arm with the battery and the PDU housed in the housing case, wherein the PDU includes an aluminum substrate disposed adjacent to one lateral surface of the battery, a control substrate spaced at a given interval apart from the aluminum substrate, and a heater element substrate disposed at a position between the control substrate and the aluminum substrate and offset from one lateral surface of the battery; and a heater element, with a higher-calorific power than each of the control substrate and the aluminum substrate, is mounted on the heater element substrate.
