Abstract
To enable communication with the outside by maintaining power supply to a radio communication part even when a main power supply circuit or harness for supplying power to the radio communication part fails in a battery monitoring device capable of performing radio communication.SOLUTION: A radio battery monitoring device 2 includes a cell monitoring IC 3 that is connected to a battery module M and detects a voltage of a battery cell C included in the battery module M, a radio communication part 4 that transmits a detection result obtained by the cell monitoring IC 3 to the outside by radio, a main power supply part 5 that supplies power from the battery module M to the radio communication part 4, and a sub power supply part 6 that supplies power to the radio communication part 4 via the cell monitoring IC 3.SELECTED DRAWING: Figure 1
