The present invention includes a CP monitoring unit configured to monitor a CP voltage applied through a CP line from the controller of the slow charging cable when the slow charging cable is connected to an inlet, a mode switching request unit configured to request mode switching to the controller of the slow charging cable by converting the monitored CP voltage to a preset mode switching voltage; a communication switching unit configured to connect a LIN transceiver for LIN communication to the CP line when the controller of the slow charging cable is switched to a LIN communication mode for software update, and a control unit configured to control the LIN transceiver to transmit a pre-stored software update file to the controller of the slow charging cable, so that the controller's software can be updated without disassembling or damaging the controller of the slow charging cable.

Software update device and software update method using same

A charging cable includes: a plurality of pins; a storage configured to store software, which controls communication with a communication device connected through at least one of the plurality of pins, controls communication with a charging object connected through the plurality of pins, controls charging of the charging object and monitors the charging; and a controller configured to: when a first voltage is applied to the at least one pin of the plurality of pins, control to output a pulse width modulation (PWM) signal having a predetermined first duty ratio corresponding to a communication enabled state with the communication device through the at least one pin; and when a second voltage is applied to the at least one pin, change to an update mode and control to output the PWM signal having a predetermined second duty ratio corresponding to the change to the update mode through the at least one pin.

Charging cable and communication device communicating with the same

A power relay assembly for an electric vehicle and a driving method thereof according to an embodiment of the present invention connect the first switching unit and the second switching unit connected in series with each other in parallel with the relay switch, and by allowing the first switching unit and the second switching unit to include semiconductor switching elements and diodes therein, not only when power is supplied from the battery to the load side, but also when charging is performed by supplying a charging current to the battery, it is possible to supply or cut off power while preventing sparks and arcs at the relay contact point.
