Problems solved by technology
In this way, not only the detection efficiency is low, but also time-consuming and labor-intensive
In addition, since the detected points are arbitrarily selected by the measurement personnel, it is difficult to evaluate the quality of the paint film with a uniform standard

Abstract
The invention relates to a measuring apparatus and a measuring method for measuring the paint film thickness of a battery cell. The measuring equipment comprises a measuring table, the bottom surface of a measured battery unit is placed on a measuring plane of the measuring table, and the measuring table is provided with the following components: a baffle plate which is fixedly arranged on the measuring table, wherein during measurement, the battery unit is in contact with the abutting surface of the baffle plate so as to limit the position of the battery unit in the direction perpendicular to the abutting surface of the baffle plate; a limiting component tightly pressing the side surface of the battery unit during measurement so as to limit the position of the battery unit in the direction vertical to the side surface of the battery unit; a sliding module capable of moving in a sliding direction parallel to the measurement plane so as to be in contact with a side surface of the measured battery cell to measure a paint film thickness of the side surface in contact with the measured battery cell; and a plurality of sensors for simultaneously measuring paint film thicknesses of a plurality of surfaces of the battery cell at a plurality of measurement points.
Description
technical field [0001] The invention relates to a measuring device and a measuring method for measuring the paint film thickness of a battery cell. In particular, the present invention relates to a measuring device and a measuring method for measuring the paint film thickness of battery cells of a high-voltage battery module. Background technique [0002] So far, battery modules have been widely used. For example, the G38 high-voltage battery module powers the BMW 5 Series plug-in hybrid. A battery module includes a plurality of battery cells connected together. The surface of the battery cell is coated with a paint film. The paint film has good adhesion, sealing and insulating functions, and strong waterproof and rust resistance, and the paint film can effectively prolong the service life of the battery. In order to obtain these characteristics of the paint film, the paint film should be compact and neat, not cracked, not swelled, not peeled off. Among them, the thickn...
