Abstract

Official abstract text for this publication.

Disclosed are an electric vehicle (EV), an EV charging stand, and a communication system therebetween, the EV including a charge control unit configured to detect a preparation state for charging a battery and output a resistance varying signal according to the detected state, and a resistor unit configured to vary a resistance value in response to the resistance varying signal, thus changing a voltage value of a state signal transmitted to the EV charging stand, and the EV charging stand including a comparator configured to receive a stage signal from the EV, compare a voltage value of the received state signal with a reference value, and output a signal in response to a result of comparing, and a control unit configured to receive the signal from the comparator and detect a preparation state for charging the battery of the EV.

First claim

Opening claim text (preview).

What is claimed is: 1. An electric vehicle (EV) charging stand, comprising: a plurality of comparators configured to receive a state signal from an electric vehicle (EV), to compare a voltage value of the received state signal with a reference value, and to output a plurality of signals in response to a result of the comparing, wherein each of the plurality of comparators has a different reference value; and a control unit configured to receive the plurality of signals outputted…
