Description

Electric vehicle

The present invention relates to an electric mobile body using a motor as a drive source. In addition, it goes without saying that the “electric vehicle” described here includes electric vehicles such as electric bicycles, motorcycles, motor tricycles, motor vehicles and the like.

Conventionally, mobile bodies such as automobiles and motorcycles generally use an engine that obtains driving force using gasoline or light oil as a driving source. However, recently, attention has been focused on the development of an electric vehicle and an electric vehicle using a motor that obtains a driving force using electric power as energy as a countermeasure for environmental protection.

Some electric vehicles are equipped with a battery, which is a secondary battery, like a personal computer, and supply electric power from this battery to a motor drive unit, a motor, a control unit, and the like. A relatively thick power line is connected between the battery and the motor drive unit or between the motor drive unit and the motor as a power supply path for supplying power used for driving the motor. Electric wires such as a wire harness and a cable harness are generally used for the power line.

An example of an electric vehicle using a wire harness in a power supply path for supplying electric power used for driving the motor from the battery to the motor drive unit or the motor can be seen in Patent Document 1. In the electric motorcycle described in Patent Document 1, a motor driving device provided immediately below a driver's seat inputs power from a battery provided near the front wheel and outputs driving power to a motor provided near the rear wheel axle. And run. In the harness structure of the electric motorcycle, a high voltage harness is connected between the battery and the motor drive device and between the motor drive device and the motor.

However, there is a concern that the number of parts increases by using so-called electric wires such as a wire harness. Furthermore, in order to drive the motor, it is necessary to transmit and receive a relatively large amount of electric power, so it is necessary to use a wire harness having a relatively large wire diameter. For this reason, if the high-voltage harness connects between the battery and the motor driving device and between the motor driving device and the motor as in the harness structure of the electric motorcycle described in Patent Document 1, the wire harness itself becomes heavy. There is concern about the weight increase of electric vehicles.

Also, there is a problem that a wire harness having a relatively large wire diameter is difficult to handle in the vehicle. As a result, there is a high possibility that it takes time when manufacturing the electric vehicle or the number of wiring steps increases, resulting in a decrease in manufacturing efficiency.

Furthermore, power loss may occur in the wiring harness as the wiring distance increases. For this reason, since the drive efficiency of the motor decreases, it is desirable to design the distance between the motor drive unit and the motor as short as possible in order to increase the drive efficiency.

The present invention has been made in view of the above points, and it is possible to suppress power loss with respect to a power supply path for transferring power between a motor, a battery, and a motor drive unit.
