Abstract:
1. An electrical storage system comprising: an electrical storage device configured to be charged and discharged; a step-up circuit configured to step up an output voltage of the electrical storage device; an inverter configured to convert a direct-current power, output from the step-up circuit, to an alternating-current power; a motor configured to operate upon reception of an output power of the inverter; a plurality of sensors each configured to detect at least one of a current value and a voltage value of the electrical storage device; and a controller configured to execute a predetermined process on the basis of the detected values of the plurality of sensors, the controller being configured to execute the predetermined process without using the detected values of the sensors when a difference between a frequency of each of the detected values and a resonance frequency of the step-up circuit is smaller than a threshold, the frequency varying with a rotation speed of the motor, and the resonance frequency varying with operation of the step-up circuit.
