The present invention discloses a correction method of a voltage sensor. A plurality of battery racks is electrically connected to a power storage device in parallel. Therefore, a voltage sensor connected to each of the battery racks can receive voltage influences of another adjacent battery rack when the voltage sensor measures the voltage of each of the battery racks. Therefore, one battery rack is electrically connected to the voltage sensor, and then a voltage value which is measured in the corresponding voltage sensor is corrected. The power storage device comprises first to N battery racks, first to N relay switches, first to N voltage sensors, and a rack control unit. |
