Electric Storage Device Monitor
First Claim
1. A monitor monitoring an electric storage device comprising:
- a measurement unit configured to detect a state of the electric storage device and obtain a detected value;
a power supply switch portion configured to switch a power supply state of the monitor between a monitoring state and a low power consumption state that requires lower power than the monitoring state; and
a wakeup timer to which actuation time is set and configured to start counting time in response to switching to the low power consumption state by the power supply switch portion and continue counting time until reaching the actuation time and output an actuation signal if reaching the actuation time, wherein;
the power supply switch portion switches the power supply state of the monitor from the low power consumption state to the monitoring state every time the wakeup timer outputs the actuation signal, the monitor further comprising;
a control unit configured to;
control the measurement unit to detect the state of the electric storage device and obtain the detected value when the power supply state of the monitor is set in the monitoring state by the power supply switch portion;
compare the detected value and a reference value; and
change the actuation time according to a comparison result of the detected value and the reference value.

Abstract
An electric storage device monitor includes a measurement unit detecting and obtaining a detected value, a power supply switch portion switching a power supply state of the monitor between a monitoring state and a low power consumption state, a wakeup timer to which an actuation time is set and starting counting time in response to switching to the low power consumption state and continuing counting time and outputting an actuation signal if reaching the actuation time, and a control unit. The switch portion switches from the low power consumption state to the monitoring state every time the wakeup timer outputs the actuation signal. The control unit controls the measurement unit to detect and obtain the detected value in the monitoring state, compares the detected value and a reference value, and changes the actuation time according to a comparison result of the detected value and the reference value.
