Provided are a communication apparatus and a communication method for message exchange with charging equipment, and an electric vehicle comprising the communication apparatus. The communication apparatus includes a communication unit provided to be coupled to the charging equipment through a first communication channel, and a control unit coupled to the communication unit through a second communication channel. The control unit determines a target polling time based on a value set to a time-out flag associated with a request message, when transmitting the request message to the communication unit at a first time point. Subsequently, the control unit periodically checks whether a response message from the charging equipment is received by the communication unit at each target polling time for a waiting period from the first time point to a second time point at which a time-out time associated with the request message has passed from the first time point.
