Embodiment Construction

[0010] Combined with the above figure 1 To attach Figure 4 Specific embodiments of the present invention will be described.

[0011] This lithium-ion cell four-channel paired tester includes a test box 10 and a test frame 20 docked with the test box 10, and the test frame 20 is provided with a battery cell slot 21 that can accommodate at least four batteries under test. The side wall of the cell slot is provided with at least four test sockets 22, and the test box 10 is provided with test interfaces 11 equal in number to the test sockets 22, and the test sockets 22 are docked with the test interfaces 11 one by one. It also includes a detection circuit 30 disposed in the test box 20 and a power supply 50 connected to the detection circuit 30 , the at least four test interfaces 11 are connected to the detection circuit 30 . On the other side wall of the cell slot 21 opposite to the side wall where the test socket 22 is installed, a mobile pressing mechanism 23 is also provid...

Abstract

A four-channel matching tester for a lithium ion battery cell comprises a testing jig (20) and a test box (10) in butt joint with the testing jig (20). A battery core groove (21) and test sockets (22) are formed in the testing jig (20). The test box (10) comprises at least four test interfaces (31), and the test interfaces (31) are correspondingly connected with the test sockets (22). The lithium ion battery core four-channel matching tester further comprises a detection circuit (30) arranged in the a control circuit (50) for controlling the detection circuit (30). The test interfaces (31) are respectively connected with the detection circuit (30) and the control circuit (50). Four products can be tested simultaneously, so that personnel need not to turn on sub-switches to meet corresponding test requirements during testing, and testing speed is greatly increased by eight times of that of single manual tests, personnel fatigue is reduced by 80%, and cost for production is greatly saved.

Description

technical field [0001] The invention relates to detection technology, in particular to automatic testing of lithium-ion electric core pairing. Background technique [0002] Nowadays, many lithium-ion batteries use two or more lithium-ion cells in series to meet the output voltage requirements. In order to ensure the service life, the parameters of two or more lithium-ion cells are required to be consistent. Usually, a multimeter with more than four and a half digits is used to measure the voltage first, and then an internal resistance meter is used to measure the internal resistance, and the cells with the same voltage and internal resistance are separated to form a pair. memory error. Contents of the invention [0003] The invention provides a four-channel paired tester for lithium-ion batteries, which can test four lithium-ion batteries at the same time, and the test steps are completed in one step, so as to solve the technical problem of low test efficiency in the prio...
