The purpose of the invention is to prevent emergency information from being erroneously transmitted when charging and discharging of the secondary battery are repeated. The current position of the host device as detected by a GPS position detection unit is acquired (100). If the position of the device has not changed for a predetermined period of time or more (NO in 104 and YES in 106), the charging and discharging history information of the secondary battery of the device is acquired (108), and whether or not the charging time or the discharging time is periodic is determined (112). If the charging time or the discharging time is not periodic, emergency information is transmitted (128), and when the charging time or the discharging time is periodic, emergency information is not transmitted (130). |
