INSPECTING DEVICE FOR BATTERY VOLTAGE DROP AND RECORDING MEDIUM RECORDING PROGRAM FOR BATTERY VOLTAGE DROP INSPECTION

摘要

PROBLEM TO BE SOLVED: To provide an inspecting device for battery voltage drop and a recording medium recording a program for battery voltage drop inspection capable of conducting inspection for battery voltage drop at a low price, with high precision. SOLUTION: A battery supplies a power source to predetermined loads including two acoustic transducers TD1, TD2 oppositely placed in a gas channel, a propagation time measuring means 1b, which measures the propagation times for the gas flow direction Y and the opposite direction to the gas flow direction Y between the transducers TD1 and TD2, and an ultrasonic flow calculating means 1c which calculates a flow based on the difference between the two propagation times. A temperature detecting means 1D detects an outdoor air temperature or the temperature in the gas channel based on the sum of the two propagation times measured by the propagation time measuring means 1b. A temperature detecting means 1a-1 in a battery voltage drop inspecting means 1a inspects the voltage drop of the battery during the interval that an outdoor air temperature exceeds a reference outdoor air temperature or that the temperature in the gas channel exceeds a reference temperature in the gas channel.
