A system (for example, a monitoring device (20)) for monitoring a first battery (in other words, a vehicle battery) provided in a vehicle (100) is provided with: a monitoring unit (21) for monitoring the electric state of the first battery (2) (for example, the vehicle battery) capable of starting a motor (4) of the vehicle (100); and a power supply unit that is a second battery (23) for supplying electric power to the monitoring unit (21). The monitoring unit (21), for example, may determine whether the motor (4) is stopped or not, and when the motor (4) is, for example, stopped, the monitoring unit (21) may monitor, as the electric state of the first battery (2), for example, the voltage of the first battery (2). |
