Abstract

A communication means (105) of a battery monitoring device (101) receives setting information (measuring parameters) about the type or structure of a storage battery (102) to be monitored from a host system (106). A setting means (107) acquires the measuring parameters and performs setting for a measuring means (103) and a digital signal conversion means (104). In other words, the setting means (107) sets, in accordance with the type or structure of the storage battery (102), the measuring parameters (namely, the measuring time interval, the measuring channel number, the measurement range and the like) for the measuring means (103) and the digital signal conversion means (104). Thus, even when the type and construction of the storage battery (102) changes, state of charge and the like of the storage battery (102) can be accurately measured and monitored by the battery monitoring device (101).
