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, a power supply that is a second battery 23 which feeds power to the monitoring unit 21, and a switching unit 22 that allows the first battery 2 and second battery 23 to be connected in parallel with each other. The monitoring unit 21 monitors the voltage V of the first battery 2 as the electric state. Based on a result of monitoring by the monitoring unit 21, the monitoring unit 21 controls the switching unit 22 so that the first battery 2 and second battery 23 can be connected in parallel with each other. The second battery 23 feeds the power, which is fed from the second battery 23, to the first battery 2. |
