An electric vehicle comprising a charger and a controller for exchanging charging-related information

摘要

Disclosed is an electric vehicle including a charger for exchanging charging-related information and a control unit. This electric vehicle has a high voltage battery; a charger for charging the high voltage battery with power supplied from the electric vehicle power supply device according to a duty ratio of a control pilot received from an electric vehicle power supply device (EVSE); and a control unit for controlling a charging operation of the charger, wherein the information exchanged between the charger and the control unit of the high voltage battery includes a charger code, a protocol version, a charging connector fastening state, a constant voltage value or a constant current value according to a charging mode, and and information related to related information, a high voltage battery cell minimum voltage value, a high voltage battery cell maximum voltage value, a remaining charge time, and information related to a charging stop due to a user interrupt, wherein the control unit includes: the high voltage battery cell minimum value and the The high-voltage battery cell maximum value is used to define the abnormal state of the high-voltage battery cell.
