Abstract

The present invention provides a circuit module which is reliably waterproof and in which wires can be easily replaced, and an electric vehicle including the same. A circuit board is accommodated in an internal space of a main body casing (10c), and a bus bar (BB) electrically connected to the circuit board is drawn out of the main body casing(10c). The bus bar(BB) is held in an internal region of a terminal holder positioned outside the main body casing(10c). One end of a harness (21) is connected to the bus bar(BB) in the internal region of the terminal holder(11), and the other end of the harness (21) is drawn out to an external space. In this state, a joint region of terminal covers(12a, 12c) is joined to a joint region of the terminal holder(11).

Description

technical field [0001] The present invention relates to a circuit module and an electric vehicle equipped with the circuit module. Background technique [0002] An example of an electric vehicle is an electric two-wheeled vehicle including a battery system, a power conversion unit, a motor, and drive wheels. When the electric motorcycle is running, the electric power supplied from the battery system is converted into electric power (driving electric power) required for driving the drive wheels by the electric power conversion unit. [0003] The power conversion unit includes electronic circuits such as an inverter circuit. Therefore, when installing a power conversion unit on an electric motorcycle used outdoors, it is necessary to reliably prevent liquid such as rainwater from coming into contact with the electronic circuit of the power conversion unit and the connection between the electronic circuit and the wiring. [0004] Patent Document 1 discloses an example of a wa...
