Battery parameter remote collection system

Abstract

The invention discloses a battery parameter remote collection system, which comprises a charging module, a discharging module, a circuit breaking module and a control module, the device further comprises a storage module, a current sampling module, a current comparison module, a first abnormal alarm module, a data display module, a wireless communication module, a temperature detection module, a temperature comparison module, a second abnormal alarm module, a heat dissipation module, an electric leakage monitoring module and a short circuit monitoring module. According to the invention, through the current sampling module and the current comparison module, a real-time current value of constant-current discharge of the discharge module is monitored in real time, and the accuracy of a lithium battery test result is ensured; moreover, once the real-time current value is found not to be matched with the preset current value, the first abnormal alarm module gives out a current abnormal alarm to remind maintenance personnel in time, so that relatively large loss is avoided.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a remote collection system for battery parameters. Background technique [0002] With the progress of society, shared electric vehicles are becoming more and more popular, so the charging cabinets for lithium batteries used by shared electric vehicles are put into various regions to facilitate users to replace the lithium batteries of shared electric vehicles in time. After many times of charging and discharging of lithium battery, its battery capacity will decay, so it is necessary to test the battery capacity of lithium battery regularly. At present, the traditional charging cabinet only has a charging function, no discharging function, and cannot test the battery capacity of a lithium battery. Therefore, when testing the battery capacity of the lithium battery, the traditional method is to recycle the lithium battery from the charging cabinet to the manufacturer or ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, for example: in the prior art, the discharge status of its discharge module is unknown, when the discharge module discharges with a constant current, failure or abnormality will directly lead to inaccurate lithium battery test results, It affects the subsequent normal use and maintenance of the lithium battery; and the parameters of the discharge module failure or abnormality cannot be known, and the staff need to conduct detailed investigations after knowing the failure or abnormality, which will waste a lot of unnecessary time
