Abstract
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.
