Description

Technical Field

[0001] The utility model relates to the technical field of railway passenger car battery measurement, in particular to a railway passenger car battery batch measurement tool. Background Art

[0002] Railway passenger car batteries refer to energy storage battery devices installed on railway passenger cars. Their main function is to supply electrical energy to on-board electrical equipment and provide convenience for driving and passengers.

[0003] The existing method of measuring batteries in railway passenger car maintenance is mainly to use a multimeter and a fork voltmeter to measure the battery voltage. Because the arrangement orientation of each single battery in the battery pack is inconsistent, the test leads must be repeatedly replaced to determine the battery polarity when using a multimeter to measure the battery voltage. The readings using a fork voltmeter are not intuitive, and it is inconvenient to measure in a narrow space. In addition, both measurement methods cannot measure the battery's loaded voltage. Because battery maintenance measurement is a job with a very high frequency, frequency and workload, the original operation method is time-consuming, inefficient, and the measurement data is incomplete, inaccurate, and erroneous.
