In addition, the power switch 24 may be configured as a pair of switches, and the pair of switches are respectively connected to a pair of relays 110 to be described later to be configured to turn on/off each relay 110 . can Accordingly, when only one of a pair of switches constituting the power switch 24 is operated to be on, only one relay 110 connected to the operated switch among the pair of relays 110 can be driven have. Accordingly, since a pair of switches must all be operated in order to drive the device, a malfunction due to a user's mistake or the like can be prevented.

The safety driving module 100 may be provided inside the main body casing 10 and may be provided to transmit power from an external power source. In this case, the external power source may be a separate power supply device provided inside the main body casing 10 or a power system provided outside the main body casing 10 .

It is designed to be supplied to However, in this case, emergency power supply is possible only when the vehicles on both sides are of the same type. In other words, when the discharged vehicle is an EV, the normal vehicle must also be an EV, and it is difficult to connect the HEV battery to the discharged EV. The reason is that the battery voltage required is different depending on the type of vehicle. That is, in the case of EV, the battery voltage is generally set at a level of 380 to 400V, whereas in the case of HEV, it is set at a level of 200 to 300V.
