PROBLEM TO BE SOLVED: To provide an electrical power system for vehicle capable of reducing erroneous determination of abnormality occurrence in a power-saving operation state.SOLUTION: An electric vehicle 100 comprises: a voltage converter 40 for converting output voltage output from a main power source 20 into accessory voltage of a vehicle accessory 30; an accessory battery 50 being charged by the accessory voltage; and a control part 60 for controlling the voltage converter 40 so that it outputs normal operation voltage in a normal control state and it outputs power saving operation voltage which is lower than the normal operation voltage as the accessory voltage in a power saving control state. The control part 60 increases the accessory voltage so that it becomes higher than the power saving operation voltage by stopping power saving control when reduction of the accessory voltage is detected in the power saving control state. |
