1. A system for supervising a battery that supplies power to an electrical unit, comprising:
- a control part that is supplied with power from the battery and executes a predetermined process when abnormal discharge of the battery occurs; and
an activation part that detects current consumed in the battery when the electrical unit and the control part are in a sleep mode and activates the control part when the activation part detects abnormal discharge that occurs when an amount of the current consumed in the battery exceeds a given threshold value.

2. A system for supervising a battery that supplies power to an electrical unit, comprising a control part that is supplied with power from the battery and executes a predetermined process when abnormal discharge of the battery occurs,
the control part including a detecting portion that detects current consumed in the battery when the electrical unit is in a sleep mode, the control part operating at a given frequency when abnormal discharge occurs in which an amount of the current consumed in the battery exceeds a given threshold value and operating at a lowered frequency when no abnormal discharge occurs.

16. A method for supervising a battery that supplies power to an electrical unit mounted on a vehicle, comprising the steps of:
-
detecting current consumed in the battery when the electrical unit and a control part that is supplied with power from the battery and executes a predetermined process when abnormal discharge of the battery occurs are in a sleep mode; and activating the control part when abnormal discharge in which an amount of the current consumed in the battery exceeds a given threshold value takes place.
