Description

Technical Field

[0001] The present invention relates to the technical field of thickness measurement and charge-discharge testing, and in particular to a multi-station multi-channel thickness measurement and charge-discharge testing device for soft-pack batteries. Background Art

[0002] Battery testing usually tests the battery's current, voltage, capacity, internal resistance, charging, discharging temperature, battery cycle life and other performance information.

[0003] When testing batteries in existing battery test boxes, the battery is usually directly clamped by a test fixture of the test box for testing. Since the test fixture is connected by wires and placed outside the box, the battery can be tested at any time, which is more convenient.

[0004] However, this testing method has great disadvantages. On the one hand, because there are often many staff members at the testing site, it is easy to accidentally touch the test fixture, resulting in unstable clamping and inaccurate test information. On the other hand, because the test fixture is only connected by wires, it is easy to be damaged over time under the weight of batteries of different models. In addition, because the connecting wires are soft, the battery will sag when clamped by the fixture, and heavier batteries may fall off. Summary of the invention

The thickness measurement adopts an electric servo motor + high-precision pressure sensor closed-loop combination test, with fast response speed and pressure regulation speed. The equipment can achieve fast one-button model change speed, thereby ensuring high-efficiency thickness measurement and OCV measurement.
