PROBLEM TO BE SOLVED: To appropriately discriminate a type of a vehicle.SOLUTION: In a charging system, when a change from 12 V to 9 V as a voltage of a CPLT signal is detected (step S11), a timer t1 is started (step S12). At this time, a CPLT signal generator generates a CPLT signal with a duty ratio of 100%. When a time X elapses in the situation, the voltage of the CPLT signal is detected (step S14). On the basis of the detection result, a type of a vehicle is discriminated (steps S15, S16). That is, a type of a vehicle is discriminated depending on whether the voltage of a CPLT signal is 9 V, or a voltage other than 9 V. |
