Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] see figure 1 , the embodiment of the present invention discloses a method for detecting the connection state of the traction battery, so as to realize online monitoring whether the connection state of each single battery in the traction battery pack is good, and accurately locate the position where the connection is loose. The method includes the following steps 101 ~Step 104:

[0042] Step 101: Measure the total internal resistance R of the traction b...

Abstract

The invention discloses a traction storage battery connection state detection method, an apparatus, a managing system and a machine shop truck. The method is performed through the following steps: measuring the total internal resistance of a traction storage battery set; checking if the total internal resistance is beyond a first preset value; measuring all the batteries in the set to get their individual internal resistances in an attempt to find the individual batteries with internal resistances that are beyond a second preset value if the total internal resistance is beyond the first preset value; outputting a test result that shows individual batteries with internal resistances beyond the second preset value are in loose connection. With such invention, online check can be done to determine if the individual batteries in a traction storage battery set are well connected and the loosening parts can be accurately positioned.

Description

technical field [0001] The invention relates to the field of railway traffic industry and storage battery application technology, and more specifically, relates to a detection method, device, management system and engineering vehicle for the connection state of a traction storage battery. Background technique [0002] The engineering vehicle traction battery management system is used to effectively manage the output state of the traction battery pack of the engineering vehicle (the traction battery pack is composed of multiple single cells connected in series), but it does not have the function of detecting the connection status of the traction battery, so It is impossible to effectively prevent the local heating or even fire of the traction battery pack caused by the loose connection of a single battery. Contents of the invention [0003] In view of this, the present invention provides a traction battery connection state detection method, device, management system and eng...
