Electrical storage system and processing method

摘要

At least one of a current value and a voltage value of an electrical storage device which is charged and discharged is detected with the use of each of a plurality of sensors. A predetermined process is executed on the basis of the detected values of the plurality of sensors The predetermined process is executed without using the detected values of the sensors in the predetermined process when a difference between a frequency of each of the detected values, which varies with a rotation speed of a motor that operates upon reception of an output power of the electrical storage device, and a resonance frequency of a step-up circuit, which varies with operation of the step-up circuit that steps up an output voltage of the electrical storage device and outputs the stepped-up electric power to the motor, is smaller than a threshold.

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.
