Title:
BATTERY DETERIORATION DEGREE MONITORING DEVICE AND BATTERY DETERIORATION DEGREE MONITORING METHOD
Document Type and Number:
Japanese Patent JP2016201247
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a battery deterioration degree monitoring device for monitoring predicted date and time when a battery deterioration degree reaches a predetermined battery deterioration degree.SOLUTION: A battery deterioration degree monitoring device 6 includes a reception unit 612, a storage unit 62, a calculation unit 63, and a transmission unit 611. The reception unit 612 receives from a charger 3 a parameter value acquired on the basis of a current value supplied to a battery 212 from the charger 3, and acquisition date and time of the parameter value. The storage unit 62 stores the parameter value and the acquisition date and time. The calculation unit 63 calculates a deterioration prediction line of the battery 212 by using the parameter value and the acquisition date and time, and calculates predicted date and time when a deterioration degree of the battery 212 reaches a predetermined value by using the deterioration prediction line. The transmission unit 611 transmits data of the predicted date and time.SELECTED DRAWING: Figure 1
