Problems solved by technology

[0003] At present, most of the instruments and tools for battery testing are desktop instruments or meters. It is inconvenient to carry the desktop testing instruments during the daily inspection of power equipment, and the battery cannot be removed from the automation equipment for testing.
The portable instrument is mainly developed for the large-capacity power starting battery, and this instrument needs an external load when testing the internal resistance of the battery, which is not very convenient for the daily inspection of the backup battery of the power equipment

Abstract

The invention relates to a battery inspection device. The battery inspection device comprises a load module used for consuming electric energy when the load module is connected to the output end of a battery; the voltage acquisition module is connected with the output end of the battery and used for acquiring load voltage when the load module is connected to the output end of the battery and also used for acquiring no-load voltage of the battery; the current acquisition module is used for acquiring load current when the load module is connected to the output end of the battery; and the processing module is used for determining the internal resistance of the battery according to the no-load voltage, the load voltage and the load current. According to the battery inspection device, the internal resistance of the standby battery can be detected more conveniently by connecting the load module in the battery inspection device, so that the daily inspection efficiency of the standby battery is improved.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a battery inspection device. Background technique [0002] With the development of communication technology, the automatic switching of power equipment is also vigorously promoted. Through a powerful communication network, various switchgears, ring network cabinets and other equipment are connected through the network, and these power equipment can be remotely controlled through the background control system. In daily use, the power supply of electrical equipment is converted from AC voltage to required DC voltage after rectification and filtering, and then used by these electrical equipment. When there is a power outage or overhaul due to line failure, there is no external power supply to use, and the backup battery built in the cabinet will be used as a power supply for power equipment. Due to the influence of product quality, use environment and other issues, the b...
