Zusammenfassung:PROBLEM TO BE SOLVED: To provide a vehicle battery monitoring system that suppresses a decrease in a remaining battery capacity of a vehicle battery.SOLUTION: A vehicle battery monitoring system (a monitoring system 20) includes a monitoring unit 21 that monitors an electric state of a first battery 2 (a vehicle battery) with which a power plant 4 of a vehicle 100 can be started, and a power supply that is a second battery 23 which feeds power to the monitoring unit 21. The monitoring unit 21 determines whether the power plant 4 is stopped. If the power plant 4 is stopped, the monitoring unit 21 monitors the voltage V of the first battery 2 as the electric state.
