Problems solved by technology

Due to the problems of less test functions, longer test cycle and complicated test process in the test tooling in the related technology
In order to comprehensively judge the performance of battery components with NFC, it is necessary to refer to the test results of multiple test systems at the same time, and the test tooling in the related art cannot meet the simultaneous testing of various performances of battery components with NFC
If the solution of testing the battery and NFC separately is adopted, after the test is completed and the battery and NFC are assembled together, system abnormalities are prone to occur

Embodiment Construction

[0047] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0048] Refer below Figure 1-Figure 7 The test fixture 100 for the battery assembly 122 with NFC according to the embodiment of the present invention will be described in detail. It should be noted that NFC1223 (Near Field Communication, Near Field Communication) is a short-range high-frequency radio technology that operates at a frequency of 13.56MHz within a distance of 20 cm. Its transmission speed has three kinds: 106Kbit / sec, 212Kbit / sec or 424Kbit / sec. At present, NFC has passed the ISO / IEC IS 18092 international standard, ECMA-340 standard and ETSI TS 102190 standard. NFC near-field communication technology is evolved from the integration of non-contact...

Abstract

The present invention discloses a testing tool and testing method of a battery component with NFC. The testing tool comprises a working table whose upper end face is provided with an X-axis cylinder and a Y-axis screw rod, a Y-axis platform which is arranged on a Y-axis screw rod, the battery component with NFC arranged on the Y-axis platform, a testing component which is arranged on the working table and comprises a voltage and current transmitter for testing the battery, an NFC chip for testing NFC, and two pairs of spring contacts, and a controller, wherein one pair of spring contacts is connected to the voltage and current transmitter, and the other pair of spring contacts is connected to the NFC chip. According to the testing tool of the invention, the battery component with NFC is arranged on the Y-axis platform, thus the testing component tests the battery and NFC of the battery component with the NFC, thus the testing tool has the functions of battery testing and NFC, the battery component with NFC can complete the tests of different projects in one testing tool, and the testing cycle is shortened.

Description

technical field [0001] The invention relates to a test tool and a test method for a battery assembly with NFC. Background technique [0002] In related technologies, the battery test system mainly uses a voltmeter and an ammeter to test the output voltage and internal resistance of the battery, and the NFC antenna test is divided into three parts, a distance test system, a radio frequency parameter test system such as RLC, and an NFC communication protocol test system. Because the test tooling in the related art has the problems of few test functions, a long test cycle and a complicated test process. In order to comprehensively judge the performance of battery components with NFC, it is necessary to refer to the test results of multiple test systems at the same time, and the test tooling in the related art cannot meet the simultaneous testing of various performances of battery components with NFC. If the solution of testing the battery and NFC separately is adopted, after t...
