摘要： A voltage measuring device includes a current detecting section that detects a charging or discharging current of a multiple-set battery; block voltage detecting sections that detect voltages of a plurality blocks respectively; and a control section that outputs a request to the block voltage detecting sections via a first communication line to acquire voltage data. Each of the block voltage detecting sections includes an active power source and a lower-power source. The control section transmits a low-power consumption mode setting signal to the block voltage detecting sections respectively when the charging or discharging current has not been detected by the current detecting section for a first time period. Each of the block voltage detecting sections switches an operating mode from a normal mode to a low-power consumption mode when the low-power consumption mode setting signal is received.

摘要： A state monitoring unit monitors a state of an assembled battery in which unit cells are connected in series. The state monitoring unit includes a plurality of voltage monitoring devices and a controller. The controller transmits a common voltage measurement command to the voltage monitoring devices connected in a daisy-chain scheme. Each of the voltage monitoring devices measures the voltage of the corresponding unit cells in response to the command that is received from the controller or the adjacent voltage monitoring device at a leading end of the communication channel, and transmits the command to the adjacent voltage monitoring device at a termination of the communication channel. When received the measured voltage from the adjacent voltage monitoring device at the termination, the voltage monitoring device transmits it with the own measured voltage. The controller determines the abnormality in reception state based on the number of received, measured voltages.
