To reduce discomfort which a user feels.SOLUTION: A charging system of an electric vehicle 100 includes: a power storage device 120; a charger 130 for receiving power from an external power source 300 so as to perform external charging to charge the power storage device 120; DCM 160 for outputting information to notify a user of information related to charging by the charger 130; and an ECU 170 for controlling the charger 130 and the DCM 160. The ECU 170 controls the charger 130 to perform external charging (step S103), controls the charger 130 to restrict charge power when a predetermined condition is established during charging (step S116), and controls the DCM 160 to output information to notify a user of a residual charge time calculated with the use of charge power immediately before restriction during restricting charge power (step S135, step S136).SELECTED DRAWING: Figure 2 【課題】ユーザが抱く違和感を低減すること。【解決手段】電動車両１００の充電システムは、蓄電装置１２０と、外部電源３００から電力を受けて蓄電装置１２０を充電する外部充電を実行するように構成された充電装置１３０と、充電装置１３０による充電に関する情報をユーザに報知するための情報を出力するＤＣＭ１６０と、充電装置１３０およびＤＣＭ１６０を制御するＥＣＵ１７０とを備える。ＥＣＵ１７０は、外部充電を実行するよう充電装置１３０を制御し（ステップＳ１０３）、充電途中に所定条件が成立した場合に、充電電力を制限するよう充電装置１３０を制御し（ステップＳ１１６）、充電電力を制限している間、制限直前の充電電力を用いて算出した残充電時間をユーザに報知するための情報を出力するようＤＣＭ１６０を制御する（ステップＳ１３５，ステップＳ１３６）。【選択図】図２
