Abstract

The invention discloses a pole piece resistance measuring instrument, a pole piece resistance measuring system and a pole piece resistance measuring method. The pole piece resistance measuring instrument comprises a control box, a base arranged on the control box, a lower pressing head arranged on the base, a pressure applying device mounted on the base, and a pressure sensor arranged on the pressure applying device, wherein the pressure applying device has an upper pressing head arranged opposite to the lower pressing head, and applies variable pressure to a pole piece resistor to be measured, which is placed on the lower pressing head, by means of the upper pressing head; the pressure sensor is arranged on the pressure applying device, and is used for acquiring the pressure applied to the pole piece resistor to be measured; the control box comprises a control main board, and a resistance measuring main board, a gas pressure regulating valve and a liquid crystal display screen which are electrically connected with the control main board; the resistance measuring main board is connected with the upper pressing head and the lower pressing head; and the gas pressure regulating valveis communicated with the pressure applying device. Based on the pole piece resistance measuring instrument, the pole piece resistance measuring system and the pole piece resistance measuring method, the variation relationship of pressure, extension and resistance is established, a measuring device which is more convenient to operate is provided, and the research of the relevant pole piece is completed.

Description

technical field [0001] The invention relates to a detection device, in particular to a pole piece resistance measuring instrument, system and method. Background technique [0002] As an energy source, the battery can obtain stable voltage, stable current, stable power supply for a long time, and a current that is little affected by the outside world, and the battery structure is simple, easy to carry, easy to charge and discharge, and is not affected by the external climate and temperature. , stable and reliable performance, play a great role in all aspects of modern social life. Since the performance of the pole piece directly affects the internal resistance of the finished battery, engineers need to test the resistance of the pole piece during the battery development and production process. [0003] The existing pole piece resistance tester can apply variable pressure to the battery pole piece, and measure the pressure value, the pole piece resistance value and the thickn...

Problems solved by technology

[0003] The existing pole piece resistance tester can apply variable pressure to the battery pole piece, and measure the pressure value, the pole piece resistance value and the thickness change value in real time, and establish the pressure, extension and resistance of the secondary battery pole piece. However, the calculation and display of other parameters of the resistance in the prior art are not intuitive enough, lack of practicability and structure with safe operation and protection, so the present invention provides a Electrode sheet resistance measuring instrument, system and method of software
