Patent ID: 8084153

Claim:
An operational guidance device for a sodium-sulphur battery that guides operation of the sodium-sulphur battery, comprising: means for inputting an operation output necessary for the sodium-sulphur battery and a time zone for requiring the operation output; means for continuously inputting a remaining battery capacity of the sodium-sulphur battery and a battery temperature of the sodium-sulphur battery; means for predicting the remaining battery capacity of the sodium-sulphur battery and the battery temperature of the sodium-sulphur battery at the final time of the time zone on the basis of the remaining battery capacity of the sodium-sulphur battery and the battery temperature of the sodium-sulphur battery, which are continuously input, the operation output necessary for the sodium-sulphur battery, and the time zone for requiring the operation output; means for comparing the predicted remaining battery capacity of the sodium-sulphur battery at the final time with a standard smallest capacity recorded in advance, and outputting guidance indicating a control target value of a battery output is to be changed because the capacity runs short when the remaining battery capacity is smaller than the standard smallest capacity; and means for comparing the predicted battery temperature of the sodium-sulphur battery at the final time with a standard highest temperature recorded in advance and outputting guidance indicating that a control target value of a battery output is to be changed when the battery temperature is high because the discharge operation stops when the temperature reaches an upper limit of an allowable range.
