Problems solved by technology

[0004] What the present invention aims to solve is that the existing monitoring device can only measure and monitor some faults of the storage battery, such as failures such as excessive internal resistance, temperature runaway and abnormal voltage, but cannot directly observe and remotely monitor the failure of the battery electrolyte loss of water problems, including batteries newly manufactured by manufacturers and running on-line

Embodiment 1

[0044] Example 1: On-site direct inspection of battery electrolyte dehydration faults

[0045] Such as figure 1 and figure 2 as shown, figure 1 Shown is a schematic structural diagram of a single battery 7 with the function of directly checking on-site the failure of the electrolyte loss of the battery pack in this embodiment.

[0046] Each of the detection probes in this embodiment is as figure 1 As shown, each detection probe includes two metal probes 1 insulated from each other. The rear end of 1 is respectively connected to the current detection module 4 installed on the surface of the battery casing through the signal connection line 3, and the positive and negative electrodes of the battery supply power to the current detection module through the power supply lines 2 and 5.

[0047] Each of the current detection modules 4 in this embodiment is as figure 1 As shown, the two metal probes 1 protruding into the same electrolyte chamber are connected or disconnected thr...

Embodiment 2

[0053] Example 2: Remote monitoring of battery electrolyte dehydration failure

[0054] The difference between the second embodiment and the first embodiment is that in the second embodiment, not only the fault information of the electrolyte dehydration in the battery 7 can be checked on site, but also the fault information of the electrolyte dehydration of the battery can be monitored through the remote maintenance terminal and the mobile terminal.

[0055] figure 2 Shown is a schematic diagram of the network topology of the remote monitoring system device for electrolyte dehydration fault of the battery 7 in this embodiment. The monitoring system for the electrolyte dehydration fault of the single battery 7 includes: an electrolyte cavity extending into the corresponding battery 7 The detection probe (the specific structure is as described in Embodiment 1), the single current detection module 4, the whole set of data collectors 8, the host computer 9 of multiple battery pac...

Embodiment 3

[0063] Embodiment 3: Detecting the dehydration degree of the electrolyte according to the change of the current in the current detection module

[0064] The difference from Embodiments 1 and 2 is that as the degree of dehydration of the electrolyte of the storage battery 7 increases, not only the liquid level of the electrolyte will drop, but the concentration of the electrolyte itself will also change. In this way, the detected current signal will change to a certain extent, and the maintenance personnel can use the first display screen on the current detection module 4 or the second display screen on the entire group of data collectors 8 or the upper position of the plurality of battery packs. The machine 9 or the maintenance terminal 10 observes the change of the current signal to judge and analyze the degree of dehydration of the electrolyte in the storage battery 7 . Of course, the lengths of the two metal probes 1 protruding into the electrolyte cavity can be set as requ...

Abstract

The invention relates to the technical field of storage battery monitoring, and discloses an onsite observation and remote monitoring system device of water loss faults of the electrolyte of a storagebattery. The device comprises a detection probe, a current detection module, a whole-group data acquirer and multiple groups of storage battery hosts. The front end of the detection probe stretches into the interior of an outer housing of the storage battery to reach the appropriate height of the electrolyte. A first display screen is arranged on the current detection module. A second display isarranged on the whole-group data acquirer. The storage battery hosts send multiple groups of whole-group storage battery electrolyte water loss fault signals which are acquired by the whole-group dataacquirer to a maintenance terminal and a mobile terminal, and timely carry out monitoring and troubleshooting on faults and hidden safety hazards caused by water loss of the electrolyte of the storage battery According to the invention, the whole-group data acquirer can be omitted in the storage battery in a small machine room, or even the hosts can be omitted, and the water loss faults of the single storage battery are directly sent to the mobile terminal of a maintainer.

Description

technical field [0001] The invention relates to the technical field of storage battery monitoring, in particular to a remote monitoring system device for battery electrolyte loss of water faults. Background technique [0002] As a chemical battery, a battery is usually filled with an electrolyte, such as an aqueous solution of sulfuric acid, and its plates are usually made of lead and lead oxides. In order to improve the service life of batteries, maintenance-free batteries are mostly used at this stage, such as valve-regulated sealed lead-acid batteries and lithium iron phosphate batteries. The original design intention of this type of battery is that it is not necessary to open the battery case during the use stage. Therefore, the entire case of this type of battery is completely cured together by casting technology, and the case is mostly made of 7-10mm thick high-strength dark opaque Made of flame-retardant plastic, it has high mechanical strength, corrosion resistance,...
