Title:
DISCHARGE TEST METHOD OF PRELIMINARY POWER SUPPLY AND MONITORING DEVICE
Document Type and Number:
Japanese Patent JP2022116392
Kind Code:
A
Abstract:
To prevent a test from being implemented while a discharge resistor is not connected due to human error, in a constant time discharge test of a preliminary power supply device.SOLUTION: A discharge test method of a preliminary power supply for testing whether or not a preliminary power supply device possesses desired performance by making a prescribed current flow to a discharge resistor from the battery-incorporated preliminary power supply device for a prescribed test time, includes: a first voltage determination process for determining whether or not a voltage difference between a measurement voltage of the preliminary power supply device at a time point at which a prescribed time shorter than the test time after a start of a test elapses, and a measurement voltage at the start of the test, is equal to or higher than a preset prescribed voltage; and a second voltage determination process for determining whether or not the measurement voltage of the preliminary power supply device at the time point at which the test time after the start of the test elapses is equal to or higher than the preset prescribed voltage. When it is determined that the voltage difference is smaller than the prescribed voltage in the first voltage determination process, a discharge test is finished.SELECTED DRAWING: Figure 3
