<P>PROBLEM TO BE SOLVED: To provide a battery residual amount notification device suppressing such an erroneous notification as notifying of the battery residual amount to be excessively larger than it actually is. <P>SOLUTION: A battery residual amount notification device 100 includes: a voltage measurement section 49 measuring the voltage of a battery 23; a main control section 50 (arithmetic section 51) calculating the battery residual amount from the measurement value measured by the voltage measurement section 49; and a display section 33 notifying of the battery residual amount calculated by the main control section 50. The main control section 50 has a storage section 53 storing that the battery residual amount is less than a first residual amount. While the storage section 53 stores that the battery residual amount is less than the first residual amount, the main control section 50 notifies of, even when a second residual amount that is equal to or larger than the first residual amount is calculated as the battery residual amount thereafter, the battery residual amount less than the second residual amount. <P>COPYRIGHT: (C)2012,JPO&INPIT |
