Abstract
Official abstract text for this publication.
A storage battery system connected to a power system includes: a storage battery; a BMU which monitors a state of the storage battery with a first sensor; a PCS which charges the storage battery and discharges from the storage battery with reference to an output value of a second sensor similar in type to the first sensor; and a control device. The control device receives a charge/discharge request and storage battery information supplied from the BMU and controls the PCS based on the charge/discharge request and the storage battery information. An abnormality detection unit of the control device acquires the output value of the second sensor from the PCS, and detects abnormality of any sensor as a result of comparison between the output value of the second sensor and an output value of the first sensor included in the storage battery information.
First claim
Opening claim text (preview).
1 : A storage battery system connected to a power system and operative based on a charge/discharge request from an energy management system that manages electric power supply/demand of the power system, the storage battery system comprising: a storage battery; a battery management unit configured to monitor a state of the storage battery with a first sensor; a power conditioning system having a function of converting AC power of the power system into DC power and charging the storage battery with the DC power and a function of converting DC power of the storage battery into AC power and discharging the AC power to the power system, the power conditioning system being configured to perform charge to the storage battery and discharge from the storage battery with reference to an output value of a second sensor similar in type to the first sensor; and a control device configured to receive the charge/discharge request and storage battery information supplied from the battery management unit and to control the power conditioning system based on the charge/discharge request and the storage battery information, wherein the control device includes an abnormality detection unit configured to acquire the output value of the second sensor from the power conditioning system and to detect abnormality of the first sensor or the second sensor as a result of comparison between the output value of the second sensor and an output value of the first sensor included in the storage battery information. 2 : The storage battery system according to claim 1 , wherein the control device further includes a malfunction indication lamp configured to be turned on when the abnormality detection unit detects abnormality. 3 : The storage battery system according to claim 1 , wherein the control device further includes an interlock processing unit configured to perform interlock processing upon detection of abnormality of the abnormality detection unit. 4 : The storage battery system according to claim 3 , wherein the interlock processing unit is configured to include processing of stopping output of a charge/discharge command to the power conditioning system as the interlock processing. 5 : The storage battery system according to claim 3 , wherein the interlock processing unit is configured to include processing of outputting a trip command to the power conditioning system as the interlock processing. 6 : The storage battery system according to claim 1 , wherein the first sensor and the second sensor are current sensors. 7 : The storage battery system according to claim 1 , wherein the first sensor and the second sensor are voltage sensors.
